Peter Donald Shack (born 20 June 1953) is a former Australian politician who served as a member of the House of Representatives from 1977 to 1983 and from 1984 to 1993.
He was a member of the Liberal Party and represented the Division of Tangney in Western Australia.
[1] Shack was educated at Wesley College, Perth and the University of Western Australia before becoming a company director and political advisor.
In 1977, aged 24, Shack was elected to the House of Representatives as the Liberal member for Tangney.
However, a redistribution for the 1984 election made Tangney notionally Liberal, forcing Gear to transfer to nearby Canning.
