Mildura Engine Origins:
The Mildura steam engine is typical of many steam engines used to pump water from the inland river systems of Victoria and New South Wales (NSW) for irrigation purposes during the 19th and early 20th century. This was started by George Chaffey who left Los Angeles in 1886 to set up Australia's first large irrigation project at Mildura.
