Moore has had three incarnations as an electorate. In its first incarnation, Moore was one of the original 30 seats contested at the 1890 colonial election.
Its latest incarnation it has existed continuously since 1950. In that time, the seat has been variously held by the two conservative forces in Western Australian politics: the Liberal Party and the National Party. The seat has never been won by the Labor Party.
Electoral reform ahead of the 2008 state election necessitated an increase in the enrolment of non-metropolitan districts. This meant that the district of Greenough was abolished, with Moore taking in most of its former territory and voters. This pitted the National member for Greenough, Grant Woodhams, against the Liberal member for Moore, Gary Snook, with Woodhams emerging the victor.
