The audit reviewed the National Aboriginal Health Strategy (NAHS) component of the Aboriginal and Torres Strait Islander Commission's (ATSIC) Community Housing Infrastructure Program (CHIP). A major NAHS objective is to improve environmental health in indigenous communities through the construction and housing and the provision of water, sewerage and related systems. The objective of the performance audit was to form an opinion on ATSIC's management of the National Aboriginal Health Strategy program in providing housing and related infrastructure to Aboriginal and Torres Strait Islander communities, and to identify areas where program administration could be improved.
