Aboriginal and Torres Strait Islander peoples are the traditional owners of Australia. It has been predicted that they have been the custodians of these lands for at least 60,000 years. Their traditional lands are inextricably linked to their languages, cultural practices and spiritual being. As the custodians they have used their traditional Indigenous knowledge to care for the land – its plants, animals and waterways, protecting unique ecosystems and maintaining sustainability. In fact, their traditional understanding reflects what has been described in the literature as a sustainable mindset. We come together as non-Aboriginal and Aboriginal educators to explore how environmental threats within the epoc of Anthropocene may be addressed using such a sustainable mindset – one reflecting both indigeneity and posthumanism perspectives. We describe three case studies showing how the use of traditional knowledge held by local Indigenous communities (IPLCs) can be used with non-Indigenous knowledge to address human induced planetary changes to protect important animal species and the land on which they live. We draw on written and oral reports from our Indigenous co-authors and data obtained informally from them by way of ‘yarning’. We describe how in the north-west of Western Australia areas of significant ecological and cultural value are being negatively affected by human-induced change threatening different animal species and ecosystems. We outline the effects of light pollution in Port Hedland and how this is disrupting the life cycle of the flatback sea turtle - culturally significant sea animals. As a point of comparison, we next describe how green back turtle and Dugong populations are being protected and sustained on the Dampier Peninsula using traditional knowledge more recently supplemented through the work of the Bardi Jawi Rangers. Finally, we examine how the Fitzroy River catchment area is increasingly under threat from water extraction and mining, but how a sustainable mindset can be used to obviate these environmental risks.
