In Australia, public lands without a specific tenure (e.g. National Park or State Forest) are referred to as Crown land or State Land, which is described as being held in the 'right of the Crown' of either an individual State or the Commonwealth of Australia; there is not a single 'Crown' (as a legal governmental entity) in Australia (see The Crown). Most Crown lands in Australia are held by the Crown in the right of a State. The only land held by the Commonwealth consists of land in the Northern Territory (surrendered by South Australia), the Australian Capital Territory, Jervis Bay Territory, and small areas acquired for airports, defence and other government purposes.
