This project (the Cross Sector project) mapped ten major systems of income support in Australia. The systems are variously regulated by state, territory and commonwealth government authorities. The approach to system governance and benefit delivery varies substantially. A diverse mix of public, for-profit private and not-for-profit entities are involved in case management, administering  income support payments and service provision. While musculoskeletal and mental health conditions are the most common, individuals may enter these systems with a wide range of health conditions ranging from mild temporary illness to serious acquired disability. The duration of benefit provision also varies markedly, ranging from days to decades.
