[1] For the 2025 Australian federal election, Labor has announced Susan Templeman will run again, and the Liberals candidate will be Mike Creed.

Voting patterns within the electorate vary significantly between the Blue Mountains and the Hawkesbury region.

For most of the first seven decades after Federation, it was a hybrid urban-rural seat that stretched from the outer western suburbs of Sydney to the Central Tablelands, including Penrith and St Marys in Sydney and Bathurst, Lithgow, Portland and Oberon in the Central Tablelands.

However, in 1977, the Central Tablelands were replaced by the Hawkesbury towns, and a 1984 redistribution carved the new seat of Lindsay out of much of its share of Sydney.

The division has changed hands many times during its long history, but in elections previous to 2007 Kerry Bartlett consolidated his 1996 win to make the electorate a fairly safe Liberal seat.

The Hawkesbury towns moved to Greenway while Macquarie was pushed some distance into the Central Tablelands, as far west as Bathurst.
