Australian heritage law

Australian heritage laws exist at the national (Commonwealth) level, and at each of Australian Capital Territory, New South Wales, Northern Territory, Queensland, South Australia, Tasmania, Victoria, Western Australia state and territory levels. Generally there are separate laws governing Aboriginal cultural heritage and sacred sites, and historical (sometimes referred to as post-contact or non-Aboriginal) heritage. State laws also allow heritage to be protected through local government regulations, such as planning schemes, as well.

Overview
The heritage laws seek to protect, preserve, present, and transmit the Australian nation's natural, cultural, and historical heritage.

National heritage
The Aboriginal and Torres Strait Islander Heritage Protection Act 1984 is legislation passed by the parliament of the Commonwealth of Australia to enable the Commonwealth to intervene and, where necessary, preserve and protect areas and objects of particular significance to Australia's Aboriginal or Torres Strait Islander peoples.

The Environment Protection and Biodiversity Conservation Act 1999 protects places of World Heritage, National Heritage and Commonwealth Heritage, The Commonwealth Heritage List includes places such as Federally owned telegraph stations, defence sites, migration centres, customs houses, lighthouses, national institutions such as Parliament and High Court buildings, memorials, islands and marine areas. The Australian National Heritage List is a heritage register, including natural, historic and indigenous places deemed to be of outstanding heritage significance to Australia.

The Natural Heritage Trust (NHT) was set up in 1997 by means of the Natural Heritage Trust of Australia Act 1997, with the main objective of conserving the "natural capital infrastructure" of Australia. Money from the NHT Account must be spent on the environment, sustainable agriculture and natural resources management (NRM). Funding is supplied to community groups and organisations for environmental and natural resource management projects, delivered via a number of different initiatives since 1997, including "Caring for Our Country". , the NHT account is funding a program known as Phase Two of the National Landcare Program.

Other Commonwealth legislation which affects Indigenous cultural heritage includes:
 * Aboriginal Land Rights (Northern Territory) Act 1976
 * Protection of Movable Cultural Heritage Act 1986
 * Native Title Act 1993

New South Wales
The goal of NSW legislation is to conserve and manage the state's cultural and natural heritage of places, objects, and features of cultural, scientific, architectural or social significance, including to the state's Aboriginal peoples, and to promote public appreciation of such places and objects. Its instruments are the National Parks and Wildlife Act 1974 and the National Parks and Wildlife Amendment (Aboriginal Ownership) Act 1996 (No. 142). The latter amends the former to "provide for Aboriginal ownership of land of Aboriginal cultural significance reserved or dedicated under that Act; to amend the Aboriginal Land Rights Act 1983 to provide for the grant of certain land claims subject to lease, and reservation or dedication, of the land under the National Parks and Wildlife Act 1974;..." and other purposes.

The Heritage Act 1977 (NSW) also provides for the conservation of environmental heritage items in New South Wales.

On occasion, damage to the environment and Aboriginal heritage has been considered in the Land and Environment Court of New South Wales, such as when Chinese billionaire Kuizhang Guo built illegal structures, planted exotic species and built a bar inside a heritage-listed Aboriginal rock cave on Crown land.

The State Heritage Inventory is a database of heritage items in New South Wales which includes:
 * declared Aboriginal Places;
 * items listed on the State Heritage Register;
 * listed Interim Heritage Orders;
 * items on State Agency Heritage Registers; and
 * items listed of local heritage significance on a local council's Local Environmental Plan.
