Since 1984, federal electoral division boundaries in Australia have been determined at redistributions by a redistribution committee appointed by the Australian Electoral Commission. Redistributions occur for the boundaries of divisions in a particular state, and they occur every seven years, or sooner if a state's representation entitlement changes or when divisions of a state are malapportioned.[1]
History
It is one of two original divisions in Victoria to have never elected a Labor-endorsed member, the other being Kooyong. It has been held by the National Party and its predecessor, the Country Party, since 1922: it is the only seat the party has held continuously since its creation. On its new boundaries, however, it takes in most of the industrial Latrobe Valley.
Then-sitting MP Peter McGauran announced his resignation in April 2008, sparking a June 2008 by-election, with the three major parties all contesting the election. The Nationals retained the seat on an increased margin, electing Darren Chester.
