Commercial or consulting archaeology (also termed cultural heritage management) only developed in earnest in Australia from the 1970s, with the advent of various state legislation requiring approvals for damage or disturbance to archaeological relics, such as the Aboriginal and Archaeological Relics Preservation Act 1972, in Victoria. The Victoria Archaeological Survey was established from the Relics Office in 1975. Historical Archaeology is generally protected by separate legislation, such as the New South Wales Heritage Act 1977, and the various other state counterparts.
