Geography

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]

As a result of a periodical boundary redistribution, from the 2025 Australian federal election, Dunkley’s boundaries will move north to include the suburbs of Carrum, Bonbeach, Patterson Lakes, Chelsea (part) and Chelsea Heights (part), while losing the southern part of Mount Eliza to neighbouring Flinders.^[2]

History

The division was created in 1984 and is named for Louisa Margaret Dunkley, a trade unionist and campaigner for equal pay for women.

It was held by the Liberal Party from 1996 to 2019, however a 2018 boundary redistribution that favoured Labor, along with Labor's increased statewide strength in Victoria resulted in Peta Murphy winning the seat for the Labor Party at the 2019 Australian federal election.^[3]
