The Division of Lyne is an Australian electoral division in the state of New South Wales. It was set up in 1949, and named for Sir William Lyne, Premier of New South Wales at the time of Federation and a minister in early Australian governments. Lyne was asked by the first Governor-General, Lord Hopetoun to form the first Federal Government. Lyne did not have the support of other politicians, and so Edmund Barton became the first Prime Minister of Australia.
