Syd Jackson

David Sydney "Syd" Jackson (6 June 1889 – 28 February 1941) was an Australian politician. He was a Nationalist Party member of the Australian House of Representatives from 1919 to 1929, representing the electorate of Bass.

Jackson was born in Launceston, Tasmania, and educated at Charles Street and Wellington Square state schools. He went into his father's manufacturing locksmith business, Launceston-based Jackson Lock and Brass Works Pty Ltd, at 13, and was taken into partnership at 21. He became secretary of the men's division of the Liberal League 1910, and was an elected warden of the Launceston Marine Board from 1916 to 1921. He was active in local sporting circles, and won the Tasmanian singles championship in lawn bowls in 1911.

In 1919, he was elected to the Australian House of Representatives as the Nationalist member for Bass, defeating Nationalist-turned-independent MP Jens Jensen. He was a member of the Standing Committee on Public Works for seven years, and was the only member of the House appointed to travel Central Australia in 1921 for the North-South Railway Enquiry. He held the seat until his defeat in 1929 by Labor candidate Allan Guy.
