Social and financial remittances from the Australian Seasonal Worker Programme (SWP) have transformed the livelihood capabilities of participating households from Timor-Leste. Timorese workers generally participate in SWP for a six-month period, with many returning for subsequent seasons. Qualitative, multi-sited research investigated the livelihood strategies of 50 Timorese worker households over a three-year period. Their net earnings averaged between 4000 and 8000 USD per season, varying with the type of employment, living costs and their ability to save. Remittances assist in strengthening livelihoods by consolidating financial, physical, social, natural and human capital, improving the quality of life for returning workers, their households and communities. Remittances maintain and consolidate social relationships, and enable investments in entrepreneurial activities, education and house building. Migrant workers exhibited a strong preference for developing social capital, with many investments in other livelihood assets underpinned by a desire to strengthen social relationships, reflecting beliefs that this enhances livelihood resilience. While remittances have made greater direct contributions to livelihoods than economic production within Timor-Leste, at least for participating households and their immediate networks, this expenditure on social capital also suggests the broader structural limitations of using remittances in a ‘productive’ way (through capital accumulation) within labour-sending countries.
