How Australian postcodes work
An Australian postcode such as 2010 has four digits. The first digit gives the state or territory: 2 for New South Wales and the ACT (whose postcodes start with 26 and 29, plus 02 for a few institutions), 3 for Victoria, 4 for Queensland, 5 for South Australia, 6 for Western Australia, 7 for Tasmania and 0 for the Northern Territory (written with its leading zero, as in 0800). A postcode usually covers one suburb or town, often several neighbouring suburbs, and a large suburb can have more than one.
