In the ACT, NSW, the Northern Territory, Queensland, South Australia, Victoria, and Western Australia, children are legally required to attend school from the age of six years old, until the minimum leaving age. In Tasmania, the compulsory school starting age is 5 years old. However, most children commence the preliminary year of formal schooling, in Pre-Year 1, between four and a half and five and a half years of age, variously called kindergarten (sometimes called Year K), reception, preparation (also abbreviated as "prep") and transition.
