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]
The Division of Macnamara was created in 2018 after the Australian Electoral Commission oversaw a mandatory redistribution of divisions in Victoria.[2] Macnamara is located in most of what was previously the Division of Melbourne Ports, which it replaced in the redistribution.[3] The division is located in Melbourne's south around the eastern shores of Port Phillip Bay and takes in the suburbs of Port Melbourne, Albert Park, Balaclava, Caulfield, Elwood, Middle Park, Ripponlea, Southbank, South Melbourne and St Kilda, as well as parts of Glen Huntly and Elsternwick.[4] It also includes the suburb of Windsor, which had previously been located in the neighbouring division of Higgins.[3]
The seat was notionally held by the Labor Party on a 1.3% margin over the Liberal Party.[3] Its predecessor, Melbourne Ports, had been held by Labor without interruption since 1906, and for over 80 years had been one of Labor's safest seats. However, Labor's hold on the seat became increasingly tenuous after a 1990 redistribution added some wealthier territory around Caulfield. Further analysis identified that the margin between the Labor Party and the Greens had narrowed to less than 0.3% as a result of recent boundary adjustments.[5]
The last member for Melbourne Ports, Michael Danby, opted not to contest the election for the new Macnamara.
The 2022 election in Macnamara was a close race between Labor's new candidate Josh Burns and the Greens' candidate Steph Hodgins-May. After several days of counting, Josh Burns narrowly won the seat, securing Labor a majority in the House of Representatives.
