Held by Labor for all but 10 years of its history, Batman traditionally had been a safe Labor seat. However, the Greens made the seat a contest beginning with the 2010 election, where they reduced Labor from a 26.0% margin to a 7.9% margin. Though Labor increased their margin against the Greens to 10.6% in 2013, the Greens reduced Labor's margin to just 1.0% in 2016. At the 2018 Batman by-election however, Labor increased their margin to 4.4% against the Greens.[2]
When it was created it covered the inner suburbs of Carlton and Fitzroy, but successive boundary changes moved it steadily northwards, ending with it including Northcote, Preston, Reservoir and Thornbury.
Located in Labor's traditional heartland of north Melbourne, Batman had been in Labor hands for all but two terms since 1910, and without interruption since 1969. It was held by Brian Howe from 1977 to 1996, a senior minister in the Hawke and Keating governments, and also Deputy Prime Minister 1991–95. Howe was succeeded at the 1996 election by Martin Ferguson, moving to Parliament after six years as President of the ACTU. Ferguson served as a senior Labor frontbencher, and a minister in the Rudd and Gillard governments, before resigning from the ministry in March 2013 after the failed challenge to Gillard's leadership. He was succeeded at the 2013 election by former SenatorDavid Feeney, who had been a parliamentary secretary in the Rudd and Gillard governments.[4]
