Outback South Australia is big, about 625,000 square kilometres or about 63% of the State. For comparison, this is an area as big as France and 2½ times bigger than the United Kingdom. But it’s home to only about 4,500 people. Its size makes the idea of traditional ‘local government’ impracticable so the OCA model is a hybrid between local government and community self-management by the 4,500 people who make it their home. The OCA represents - and advocates for - the interests of these people and their families.
