Western Australia—Legislative Assembly
The district was located east of Perth.
First created fo the 1974 state election, the district's first member was Labor's James Moiler, who had at that stage already served one term as the member for Toodyay. The district switched parties at the 1977 state election with the election of Liberal candidate Tom Herzfeld. Herzfeld served two terms in parliament before being defeated by just 16 votes by Labor candidate Gavan Troy at the 1983 state election. The result was challenged in the Court of Disputed Returns and the election was declared void, but Troy won the resulting by-election by a larger margin, and went on to serve as a minister in the Burke, Dowding and Lawrence governments from 1986 until 1991.
