Jack Kelvin Paff (born 11 May 1938) is a former Australian politician. Born in Taree, New South Wales, he served in the Citizens Military Force and rose to the position of sergeant. Before entering politics, he was a stationmaster with New South Wales Railways and then served in the Queensland Police Force. In 1998, he was elected to the Queensland Legislative Assembly as a member of Pauline Hanson's One Nation, representing the seat of Ipswich West. He remained in One Nation until December 1999, when he and the other One Nation MPs left the party to form the City Country Alliance under the leadership of Bill Feldman. Paff continued as party whip for the new grouping, and was the spokesperson for Law (Attorney-General), Justice and the Arts, Communication and Information, Local Government and Planning, Regional and Rural Communities, State Development and Trade. He was defeated in 2001 by Labor's Don Livingstone, whom Paff had defeated in 1998.[1]
