PS Enterprise is an 1878 Australian paddle steamer, currently owned by the National Museum of Australia in Canberra.

[3] It has a shallow draft of 75 centimetres (30 in),[1] allowing it to cope with the low water levels of the Australian rivers, and a maximum speed of 5 knots (9 km/h; 6 mph).

It changed hands several times over the years, and has been used as a cargo ship (towing barges[4][5]), a store, a fishing boat and a houseboat, operating on the Murray, Darling and Murrumbidgee Rivers.

From 1919 until 1945 it was owned by Augustus Creager, who, with his wife Hilda, raised a family of five children living on board.

[2][6] In 1973, amidst a general renewed interests in steamboats, Enterprise was restored by enthusiast Graeme Niehus and his father, and subsequently raced against other paddle boats.
