Habitat context and functional growth traits explain alien plant invader impacts on native vegetation communities

Examining context-dependency of ecological impacts of alien plant invasions is critical to further understand the mechanisms driving impacts. We examined how different regional and local habitat contexts influence the abundance-impact associations of an invasive ground-creeper, Tradescantia fluminensis, in native forests across eastern New South Wales (NSW), Australia. Invader impacts were assessed using surveys of resident vegetation at 97 monitoring plots (5 m × 2 m) located at 14 sites, representing a gradient of T. fluminensis abundance. We modelled the association of T. fluminensis invasion with native species richness (number per plot) and foliage cover across two different habitat types (remnant vs replanted forests), two vegetation community types (wet sclerophyll vs river oak forests), and two regions (northern vs. southern NSW). We also modelled variation in native species responses amongst different functional growth forms. The negative associations of T. fluminensis and native species communities was more strongly explained by local site variables (i.e., habitat type, community type, plant growth form) than regional scales. Native richness reduced with invasion in river oak but not wet sclerophyll forest. Native richness also declined in remnant forest, although no effect of invasion was observed in replanted forest. Surprisingly, native species growth forms most like T. fluminensis (ground layer herbs, ferns) were more resistant to reductions in native richness compared to divergent forms (shrub, tree and woody vine recruits). This study highlights the need to explicitly consider local community and habitat context and functional representation of resident species when considering invader impacts and site-level management plans.

Economic costs of responders for responding to residential fire incidents in new south wales, Australia

One in five fire incidents in Australia is residential fire. There is a paucity of data on the economic costs of responding to residential fires. The limited research has centred on fire services without due recognition of the involvement of other agencies. This study aims to determine the economic costs of all first responders for responding to New South Wales (NSW) residential fires. This was conducted using Fire and Rescue NSW administrative data from 44,623 residential fire incidents between January 2005 and March 2015, together with other publicly available information. Costs were expressed in terms of constant 2022 Australian dollars. Fire and Rescue NSW personnel spent an average of 130 min per residential fire, involving eight personnel. The total economic costs to all responders, including personnel and resources, for responding to residential fires, averaged AU$ 9.5 million per annum and AU$ 2200 per incident. Both the total economic costs and costs per incident increased significantly by 1.4 % and 2.8 %, respectively, over a decade. This pioneering study sheds light on the costs of first responders for residential fires, providing valuable insights for policymakers to enhance preparedness for residential fires and associated consequences, recognising the broader economic impact extending beyond the primary agency.

Challenging the monolingual mindset: language teachers’ pushback and enactment of critical multilingual language awareness in Australian schools

ABSTRACT This study critically interrogates dominant discourses and practices in school settings, which reveal the legitimisation and perpetuation of a monolingual mindset. Through the lens of ‘Critical Multilingual Language Awareness’ (CMLA), this research unpacked the experiences and practices of language teachers who implement the New South Wales (NSW) mandated language curriculum and, where possible, create opportunities for adjustments to language syllabi for greater awareness of diversity and plurilingualism. Data was gathered through in-depth semi-structured interviews with four high-school language teachers at independent schools in NSW, Australia. The interview addressed teachers’ proficiency and knowledge of subject matter, their views of the (im)possibilities of the NSW language curriculum for developing plurilingual learners, and perceived challenges that appear to prevent multi/plurilingualism from being at the forefront of Australian language education. Findings revealed that despite teachers’ strong commitment to languages education, they feel discouraged about the limited focus at national and State government levels on consistent and systematic multilingual education. This not only diminishes every effort made by teachers to transform pedagogies for pedagogies for multilingualism but also legitimises a dominant underlying rhetoric of monolingualism that does not adhere to the principles of educating for democratic citizenship.

The New South Wales Mouse Plague 2020-2021: A One Health description

A mouse plague occurred in Eastern Australia from spring 2020 to winter 2021, impacting an area of around 180,000 km2. It harmed human physical and psychological health, damaged the natural and built environment, and endangered farmed, domestic and native animals. However, the mouse plague was overshadowed by the COVID-19 pandemic, especially as the end of the plague coincided with the arrival and surge of the COVID-19 delta strain in rural New South Wales (NSW). In this article, we systematically overview the multiple impacts of the plague and highlight their complex interactions. Using a One Health framework, we comprehensively review the i) human, ii) animal and iii) environmental impacts including economic dimensions. Given the damage that the mouse plague caused to infrastructure, we consider the environment from two perspectives: the natural and the built environment. This One Health description of the 2020–2021 mouse plague identifies priorities for preparedness, response and recovery at local, regional land levels to inform response and management of future mouse plague events in Australia. It also highlights the need for ongoing collaboration between researchers and practitioners in the human, animal and environmental health sectors.

Indigenous Water Engineering and Aquaculture Systems in Australia: The Budj Bim Cultural Landscape and Baiame’s Ngunnhu (the Brewarrina Aboriginal Fish Traps)

In Australia, First Peoples have practiced sustainable forms of water management for millennia. They have done so by respectfully caring for Country through their use of engineering and maintenance processes, including sophisticated fish and eel trapping structures and weir systems. Some of the largest continuing sites of water engineering and aquaculture in the world are still visible and used by local Aboriginal groups – the Budj Bim in Victoria and Baiame’s Ngunnhu (Brewarrina Aboriginal fish traps) in New South Wales (NSW). Recent scholarship and successful heritage listings, including the World Heritage listing of the Budj Bim Cultural Landscape and work by and with traditional custodians in these river systems, are starting to bring into public discourse and knowledge these sophisticated and important places of global cultural significance. The principles used in the design of these systems, and the social and environmental contexts of their maintenance and convening power over millennia, are particularly important as we navigate new technologically mediated forms of water management today and into the future. These management challenges include communities in Australia and globally working on the importance of significant places, values, rights, justice and voice for Indigenous peoples in building sustainable futures, including through innovation and safe, sustainable and responsible cybernetic approaches to water governance and the SDGs.

Knowledge and attitudes towards eating disorders: A survey of psychiatrists and psychiatry trainees in New South Wales.

To evaluate New South Wales (NSW) psychiatrists' and psychiatry trainees' knowledge and attitudes towards eating disorders (EDs). A total of 1781 psychiatrists and trainees in NSW were invited to complete an anonymous questionnaire assessing ED confidence, knowledge and attitudes. A total of 51 doctors responded to the survey, with 38 completing all items. Significant knowledge gaps were revealed. Respondents expressed a desire for more ED training. Enhanced ED training in psychiatry education and incorporating the lived experience voice to improve attitudes appear necessary.

Evaluation of precipitation extremes in ERA5 reanalysis driven regional climate simulations over the CORDEX-Australasia domain

Reanalysis-driven regional climate simulations using the Weather Research and Forecasting (WRF) model in New South Wales (NSW) and Australian Regional Climate Modelling (NARCliM) Version 2.0 are assessed for capturing precipitation extreme indices. Seven configurations of the WRF model driven by ECMWF (European Centre for Medium-Range Weather Forecasts) Reanalysis v5 (ERA5) for Australia from 1979 to 2020 at 20 km resolution are evaluated. We assess the spatiotemporal patterns of six selected Expert Team on Sector-Specific Climate Indices (ET-SCI) precipitation extremes by comparing regional climate model (RCM) simulations against gridded observations. The RCMs evaluated have varying levels of accuracy in simulating precipitation extremes. While they capture climatology and coefficient of variation of precipitation extremes relatively well, temporal correlation and trend reproduction present challenges. Some RCMs perform more effectively for specific extreme indices, while others encounter challenges in accurately replicating them. No single RCM excels in all aspects, highlighting the need to consider specific strengths when selecting RCMs for global climate model (GCM) driven simulations.

Visualising Daily PM10 Pollution in an Open-Cut Mining Valley of New South Wales, Australia—Part I: Identification of Spatial and Temporal Variation Patterns

The Upper Hunter Valley is a major coal mining area containing approximately 40% of the currently identified total coal reserves in New South Wales (NSW), Australia. Due to the ongoing increase in mining activities, PM10 (airborne particles with an aerodynamic diameter of less than 10 micrometres) pollution has become a major air quality concern in local communities. This paper summarises the spatial and temporal variability modes of PM10 pollution in the region, based on long-term multi-site monitoring data and the application of the rotated principal component analysis (RPCA) and wavelet analysis techniques. RPCA identified two distinct air quality clusters/subregions in the valley: one in the west/northwest and the other in the southeast. Wavelet analysis revealed the annual cycle to be the most persistent temporal mode of PM10 variability in both subregions, with intermittent signals also observed at time scales of around 120, 30~90, and under 30 days. How these variation modes are related to the effects of local PM10 emissions and the influence of meteorology at different time scales deserves further attention in future work. The findings will be used in air quality reporting and forecasting in NSW. The methodology and results can also be useful for air quality research in similar regions elsewhere.

School-Based Integrated Care Within Sydney Local Health District: A Qualitative Study About Partnerships Between the Education and Health Sectors.

The unmet physical and mental health needs of school-aged children (5-18 years) in New South Wales (NSW), stemming from poor access and engagement with healthcare, can be addressed by school-based integrated care (SBIC) models.This research aims to understand why and how partnerships between the health and education sector, in SBIC models, are important in providing care for children, and to identify the facilitating factors and barriers for implementation. A qualitative study was conducted using semi-structured interviews and thematic analysis. The principles of the 'Integrated People-Centred Health Service (IPCHS)' framework and Looman et al's (2021) implementation strategies for integrated care were considered. Themes within IPCHS framework: Strategy 1: Engaging and empowering people and communities - community-driven models, improved access to healthcare, positive outcomes for children and families, 'connection', and service provision for marginalised populations; Strategy 2: Strengthening governance and accountability - system integration and developing evidence base; Strategy 3: Reorienting the model of care - shifting healthcare to schools reduces inequity and provides culturally safe practice; Strategy 4: Coordinating services within and across sectors - integrating care and stable workforce; Strategy 5: Creating an enabling environment: leadership, stakeholder commitment, and adequate resourcing. Potential strategies for implementing SBIC models across NSW include community consultation and co-design; building multidisciplinary teams with new competencies and roles e.g. linkers and coordinators; collaborative and shared leadership; and alignment of operational systems while maintaining a balance between structure and flexibility. SBIC models require high-level collaboration across sectors and with communities to provide a shift towards child and family centred care that improves engagement, access and outcomes in health delivery.

Kalgal Burnbona: An Integrated Model of Care Between the Health and Education Sector.

Kalgal Burnbona is a framework developed for applying school-based integrated care (SBIC) across Sydney Local Health District (SLHD). Kalgal Burnbona is an innovative and integrative framework developed to provide holistic, integrated, multidisciplinary child and family centred care to school-aged children from priority populations within SLHD, such as those belonging to the Aboriginal community. The expected outcomes include improved health, behavioural, education and social outcomes. This article contextualises the development of the Kalgal Burnbona framework from its beginnings as a pilot site called Ngaramadhi Space (NS) within the Healthy Homes and Neighbourhoods (HHAN) initiative, through to its evolution to an integrated partnership between the New South Wales (NSW) health and education sector. An example of how the framework can be implemented in other settings within SLHD is described. A tiered approach to integrated care across SLHD is postulated based on evidence from a mixed methods evaluation of NS and in line with the Rainbow Model of Integrated Care (RMIC). Kalgal Burnbona is an example of a community-driven response through collaborative partnerships to improve health, education and social outcomes. The framework described provides structure for multisector teams to work within, recognising that each community and school has its own history and needs. The Kalgal Burnbona model can be scaled up to serve a wider network of students across SLHD. The initial successes of the model, which include improving access and engagement for children with unmet physical health, mental health and social needs while being accepted by communities provide evidence for policy changes and advocacy that centre on collaborative cross-sector partnerships.

IntroductionRadiologist shortages threaten the sustainability of breast cancer screening programmes. Artificial intelligence (AI) products that can interpret mammograms could mitigate this risk. While previous studies have suggested this technology has...

FITNESS FOR RECOVERY- FEASABILITY AND IMPACT OF AN EXERCISE PROGRAM DURING RESIDENTIAL REHABILITATION

INTRODUCTION AND AIMS Opioid use disorder has the lowest quality of life (QOL) and highest disease burden of all substance use disorders (SUD). While opioid treatment does improve QOL, it remains below that of the general population. Previous reviews have indicated that exercise offers benefits for QOL, however the evidence in an opioid treatment population is lacking. This study investigates the feasibility and impact of a 10-week exercise intervention on QOL and mood in a residential rehabilitation program. METHODS Participants admitted to an opioid substitution program within the We Help Ourselves (WHOS) rehabilitation service in Sydney, NSW Australia were invited to participate in a 10-week exercise intervention. Participants completed baseline screening assessing QOL, mood, exercise habits, and a fitness assessment. Willing participants then completed a twice weekly program delivered as part of the group therapy program. Sessions typically consisted of bodyweight exercises such as squats and push ups, and boxing. Following the completion of the training program assessments were repeated. Within group pre-post measures for QOL and mood outcomes were analysed using two-way ANOVA. This clinical trial was registered with Australia New Zealand clinical trial registry (ACTRN12622000213741). RESULTS 45 Participants completed baseline assessments with nine participants completing the intervention and follow up assessment. Significant improvements were seen in QOL (p=0.005), Psychological distress (p<.001), and PCL-5 scores (p=.011). Participants performed well in grip strength, but below norms in all other exercise assessments. Exercise capacity improved following the intervention. CONCLUSIONS Exercise programs are both feasible and beneficial when run as part of SUD improving a range of QOL and mood outcomes. Exercise capacity was generally poor, however improved through the course of the study, often nearing population norms. Exercise should be integrated widely as an adjunct therapy for SUD.

Client and staff perceptions of acceptability of MyCheck: a direct-to-pathology telehealth and e-testing service for comprehensive bloodborne virus and sexually transmissible infection screening.

Background Sydney Sexual Health Centre (SSHC) is the largest sexual health clinic in New South Wales (NSW), servicing clients at high risk of sexually transmissible infections and bloodborne viruses. SSHC piloted a direct-to-pathology pathway that facilitated bloodborne virus/sexually transmissible infection testing at one of the ~500 participating pathology collection centres located across NSW. This qualitative study sought to understand SSHC client and provider perspectives of acceptability of the MyCheck intervention. Methods Semi-structured in-depth interviews were conducted with 11 clients who underwent testing via the MyCheck pathway and eight staff members involved in implementing MyCheck. The seven components of Sekhon's Theoretical Framework of Acceptability informed this analysis. Results Participants broadly conveyed 'affective attitude' toward the MyCheck pathway. The telehealth intervention reduced client 'burden' and 'opportunity cost' through enabling greater testing convenience at a location suitable to them and provided timely results. Issues of 'ethicality' were raised by clients and staff as pathology centre staff were, on a few occasions, regarded as being judgmental of SSHC clients. 'Intervention coherence' issues were largely attributed to pathology centre personnel being unfamiliar with the intervention, with billing issues being a recurrent concern. Participants perceived MyCheck as an 'effective' testing pathway. SSHC staff were able to offer the intervention with ease through seamless IT integration ('self-efficacy'). Conclusion The MyCheck intervention was perceived by both SSHC clients and staff as an acceptable bloodborne virus/sexually transmissible infection testing pathway. However, further work is required to address stigma experienced by some clients when attending pathology collection centres.

Prevalence and factors associated with mental health status in Parkinson's disease: Data from the 45 and Up Study.

Parkinson's disease (PD) is associated with a range of non-motor symptomologies such as anxiety and depression. The purpose of this research was to investigate the prevalence and factors associated with mental health status in persons with PD. This retrospective data linkage study analysed a subset of data from the Sax Institute's 45 and Up Study based in the population of the state of New South Wales (NSW), Australia. Data was analysed between 2005-2009 of persons who self-identified with PD. Secure data access was provided through the Sax Institute's Secure Unified Research Environment (SURE). Participants were aged 45+ years of age and living in NSW, Australia. Regression analysis was performed on psychological distress (K10), previous diagnosis of anxiety, and/or depression, with independent variables for locality, demographic, health, medical, and sociocultural factors. A total of 1676 persons self-identified with PD from the 45 and Up Study Wave 1 baseline and were linked to the 2010 Social, Economic and Environmental Factors (SEEF) survey dataset. Mental health manifestations are common in PD with 29% and 32% reporting a previous medical diagnosis of anxiety and depression, respectively. Rural locality was associated with an increased likelihood of psychological distress, anxiety, and depression compared to metropolitan locality. Mental health status in PD was associated with living in rural areas, medical service access, female gender, ageing, physical mobility, Australian born, social interactions, and in a coupled relationship. Further research is required on the longitudinal impact of these associations on mental health in PD.

Bystander cardiopulmonary resuscitation differences by sex – The role of arrest recognition

PurposeTo assess whether bystander cardiopulmonary resuscitation (CPR) differed by patient sex among bystander-witnessed out-of-hospital cardiac arrests (OHCA). MethodsThis study is a retrospective analysis of paramedic-attended OHCA in New South Wales (NSW) between January 2017 to December 2019 (restricted to bystander-witnessed cases). Exclusions included OHCA in aged care, medical facilities, with advance care directives, from non-medical causes. Multivariate logistic regression examined the association of patient sex with bystander CPR. Secondary outcomes were OHCA recognition, bystander AED application, initial shockable rhythm, and survival outcomes. ResultsOf 4,491cases, females were less likely to receive bystander CPR in private residential (Adjusted Odds ratio [AOR]: 0.82, 95%CI: 0.70–0.95) and public locations (AOR: 0.58, 95%CI:0.39–0.88). OHCA recognition during the emergency call was lower for females arresting in public locations (84.6% vs 91.6%, p = 0.002) and this partially explained the association of sex with bystander CPR (∼44%). This difference in recognition was not observed in private residential locations (p = 0.2). Bystander AED use was lower for females (4.8% vs 9.6%, p < 0.001); however, after adjustment for location and other covariates, this relationship was no longer significant (AOR: 0.83, 95%CI: 0.60–1.12). Females were less likely to be in an initial shockable rhythm (AOR: 0.52, 95%CI: 0.44–0.61), but more likely to survive the event (AOR: 1.34, 95%CI: 1.15–1.56). There was no sex difference in survival to hospital discharge (AOR: 0.96, 95%CI: 0.77–1.19). ConclusionOHCA recognition and bystander CPR differ by patient sex in NSW. Research is needed to understand why this difference occurs and to raise public awareness of this issue.

Sexually transmitted infections: Prevalence and clinical outcomes among pregnant women in Western Sydney.

We report the prevalence, characteristics and clinical outcomes of women with sexually transmitted infections (STIs) in pregnancy in the Western Sydney Local Health District (WSLHD) serving a large culturally and socio-economically diverse community in New South Wales (NSW), Australia, over the last 10 years. A retrospective cohort study of all pregnant women booked for antenatal care at three hospitals in WSLHD between September 2012 and August 2022 inclusive. Characteristics and birth outcomes associated with STIs diagnosed in pregnancy (chlamydia, gonorrhea, and syphilis) are reported using multivariable logistic regression adjusting for relevant confounders. During 2012-2022, there were 102 905 births and 451 women (0.44%) with an STI diagnosis during pregnancy. The number of women with a history of chlamydia prior to their current pregnancy has increased over the last 10 years (P < 0.001). STIs in pregnancy were more common in younger women aged <20 years (adjusted odds ratio [aOR] 7.30, 95% confidence interval [CI] 5.04-10.57), 20-24 years (aOR 3.12, 95% CI 2.46-3.96), and >40 years (adj OR 1.67, 95% CI 1.07-2.59), in women with body mass index >30 (aOR 1.73, 95%CI 1.37-2.19), and those who smoked (aOR 2.24, 95% CI 1.71-2.94) and consumed alcohol (aOR 3.14, 95% CI 1.88-5.23) and illicit drugs (aOR 2.10, 95% CI 1.31-3.36). STIs in pregnancy were borderline associated with stillbirth (aOR 2.19 95% CI 0.90-5.36) but did not have a significant impact on preterm birth (aOR 1.21, 95% CI 0.87-1.68), admission to neonatal intensive care unit (NICU) (aOR 1.02, 95% CI 0.77-1.34), or having a small-for-gestational-age (SGA) baby (aOR 0.97, 95% CI 0.74-1.27). Sociodemographic factors such as age, weight, smoking, and alcohol and drug use, were associated with the STI incidence in pregnancy. While the latter did not have an impact on preterm birth, NICU admission, and SGA in our cohort, there was a borderline association with stillbirth. Future research should identify barriers and facilitators to testing in a multicultural population and understanding the drivers of higher rates of STIs in certain population groups.

Investigating midwives and nurses reporting of ‘infant feeding at hospital discharge’: an online survey across NSW Australia

BackgroundThe collection of data on ‘infant feeding at hospital discharge’ is used to monitor breastfeeding outcomes, health service benchmarking, and research. While some Australian states have clear definitions of this data collection point, there is no operational definition of ‘infant feeding at hospital discharge’ in the Australian state of New South Wales. Little is known about how midwives interpret the term ‘infant feeding at hospital discharge’, in particular, the timeframe used to calculate these important indicators. The purpose of this study was to explore midwives’ and nurses’ practices of reporting ‘infant feeding at hospital discharge’ in the Australian state of New South Wales.MethodsAn online survey was distributed across public and private maternity hospitals in New South Wales, Australia. The survey asked midwives and nurses their practice of reporting ‘infant feeding at discharge’ from categories offered by the state Mothers and Babies report of either “full breastfeeding”, “any breastfeeding”, and “infant formula only”. The Qualtrics survey was available from December 2021 to May 2022.ResultsThere were 319 completed surveys for analysis and all 15 NSW Health Districts were represented. Some participants reported using the timeframe ‘since birth’ as a reference (39%), however, the majority (54%, n = 173) referenced one of the feeding timeframes within the previous 24 h. Most midwives and nurses (83%, n = 265) recommended 24 h before discharge as the most relevant reference timeframe, and 65% (n = 207) were in favour of recording data on ‘exclusive breastfeeding’ since birth.ConclusionThis study identified multiple practice inconsistencies within New South Wales reporting of ‘infant feeding at hospital discharge’. This has ramifications for key health statistics, state reporting, and national benchmarking. While the Baby Friendly Hospital Initiative accreditation requires hospitals to demonstrate and continuously monitor at least a 75% exclusive breastfeeding rate on discharge, only 11 New South Wales facilities have achieved this accreditation. We recommend introducing an option to collect ‘exclusive breastfeeding’ on discharge’ which is in line with participant recommendations and the Baby Friendly Hospital accreditation. Other important considerations are the updated World Health Organization indicators such as, “Ever breastfed”; “Early initiation of breastfeeding” (first hour); “Exclusively breastfed for the first two days after birth”.

Implementation of a simulation free palliative Radiation Therapy pathway: An inter-professional collaborative project

The Western New South Wales Local Health District (WNSWLHD) has a significant footprint within the state of New South Wales (NSW). Due to the significant size of the WNSWLHD, patients residing in the local health district face many barriers to receiving Radiation Therapy. The inter-professional collaboration behind the successful implementation and evaluation of a simulation free pathway for palliative Radiation Therapy in WNSWLHD will be explored within this narrative. The process known in WNSWLHD as Medical Imaging Simulated Radiation Therapy (MISRT) removes the need for a computed tomography (CT) simulation and allows for palliative Radiation Therapy to be planned on previously acquired diagnostic CT imaging. The implementation of MISRT has required significant inter-professional collaboration. This also extends to inter-centre partnership, intra-district cooperation with Medical Imaging and inter-discipline teamwork amongst Radiation Oncologists, Radiation Oncology Medical Physicists, Radiation Oncology Nursing and Radiation Therapists. The impact and involvement of the inter-disciplinary teamwork will be explored. The methods of implementing MISRT will be outlined covering changes to standard workflow, educational requirements and inclusion criteria. The evaluation of the implementation will also be covered with two evaluation surveys being conducted. Inter-professional communication, education, teamwork and collaboration is highlighted to demonstrate improving access to quality care in a rural and regional healthcare setting whilst reducing known barriers to accessing Radiation Oncology.

Restoring Children From Out‐of‐Home Care: Insights From an Aboriginal‐Led Community Forum

ABSTRACTRestoring children from out‐of‐home care (OOHC) to their families is the preferred outcome for all children removed by child protection services, yet little is known about how restoration processes are experienced by families and services supporting them. This paper provides important insights about Aboriginal child restoration from 40 practitioners and stakeholders at a community forum led by Aboriginal Community Controlled Organisations in regional New South Wales (NSW), Australia. This is one component of larger Aboriginal‐led research, which investigates child protection experiences and pathways to successful restoration in NSW and the data source for this paper. The community forum explored the issues for families navigating family preservation, OOHC and restoration within child protection and legal systems. Findings include the need for a continuum of support for families throughout their engagement with child protection systems and crucially following the removal of their children. Barriers to effective restoration practice included a lack of access to meaningful and ongoing preservation services, insufficient cultural care planning and family finding efforts that are often too late, the pressure on services to support families without adequate capabilities or enough resourcing, the lack of transparency and the complexities in navigating the restoration process, and the lack of culturally informed support for children and their families while children are in care. Implications for policy and practice are discussed. This paper contributes to understanding practice, processes and barriers for restoration, particularly focused on the perspectives of Aboriginal families and communities, with potential insights for practice within Australia and internationally.

Characterising continental shelf waves and their drivers for the southeast coast of Australia

Low-lying, developed areas in New South Wales (NSW) are susceptible to extended periods of inundation, which cannot be attributed to tides or local synoptic conditions. This inundation is often associated with relatively small water level anomalies but is persistent enough to damage the built environment. Due to their long duration, continental shelf waves (CSWs) are one of the mechanisms of concern associated with extended coastal inundation. These waves are caused by a range of synoptic disturbances occurring along the mid-latitudes and they travel anticlockwise along the coast (in the southern hemisphere), reaching low latitudes of NSW. This study investigates the characteristics of CSWs that travel along the NSW coast, their generation and propagation mechanisms in relation to local synoptic and oceanic conditions, and their potential modulation by two major large-scale climate modes: the El Niño/Southern Oscillation and the Southern Annular Mode (SAM). We used time series of daily tidal residuals from 1994 to 2015 from nine locations along the NSW coast and used a peak over threshold approach to identify 29 waves which had an average amplitude of 0.3 m, mean period of 15 days (ranging from 8 to 20 days), and a highest occurrence in autumn and winter. The generation of CSWs is tightly coupled to the subpolar jet, the belt of westerlies, and the subtropical ridge, confirming that large-scale atmospheric circulation is a key element in the generation and propagation of CSWs. Through analyses of the inverse barometer, we found that CSWs propagate freely up to the north coast of NSW, independent of local weather conditions. We also found that CSWs are more frequent during the positive phase of SAM combined with La Niña and during neutral SAM combined with El Niño events. This study provides the longest database to date of CSWs for NSW, alongside new insights into their characteristics and timing and frequency of occurrence. Importantly, this information can be used to monitor their occurrence and forecast their impact, including the number of days taken for a wave to reach different locations along the NSW coast.
