Historic Shipwrecks Act 1976

The Historic Shipwrecks Act 1976 was an Act of the Parliament of Australia which legally protected historic shipwrecks and any relics or artefacts from those wrecks. == The Act == The Act automatically affects all shipwrecks that meet the "historic" criteria (generally defined as vessels more than 75 years old, although newer ships with historic value may be placed under the Act) and are in Australian Commonwealth waters (between the low-tide mark and the edge of the continental shelf): complementary state and territory legislation protects shipwrecks in state and territory waters including rivers and bays.
