Education in Australia encompasses the sectors of early childhood education[8] (preschool) and primary education (primary schools), followed by secondary education (high schools), and finally tertiary education, which includes higher education (universities and other higher education providers) and vocational education (registered training organisations).[9] Regulation and funding of education is primarily the responsibility of the States and territories;[2] however, the Australian Government also plays a funding role.[10] Education in Australia is compulsory between the ages of four, five, or six[11] and fifteen, sixteen or seventeen, depending on the state or territory and the date of birth.[12] For primary and secondary education, government schools educate approximately 60 per cent of Australian students, with approximately 40 per cent in non-government schools.[5] At the tertiary level, the majority of Australia's universities are public, and student fees are subsidised through a student loan program where payment becomes due when debtors reach a certain income level.
