John Duncombe Fischer (born 3 June 1947) is a former Australian politician. Born in Fremantle, Western Australia, he was a business proprietor before entering politics. In 2001, he was elected to the Western Australian Legislative Council for Mining and Pastoral, representing One Nation. After the resignation of Paddy Embry, he and Frank Hough were the party's only MPs in Western Australia. In June 2004, he and Hough both resigned from the party to sit as independents. Fischer, unlike Embry and Hough, did not join the New Country Party and was defeated as an independent in 2005.[1] He has subsequently contested elections affiliated with Graeme Campbell, a former Labor MP and founder of the Australia First Party.
