Federal electoral division boundaries in Australia are 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]
The seat was notionally held by the Labor Party on a 0.6% margin over the Greens, when compared to the result for Batman at the 2016 federal election.[3] At the 2019 election incumbent Ged Kearney received a swing of over 13% making the seat once again safe for the ALP.
