    Division of Casey

    Casey was created in 1969, taking in a stretch of Melbourne's new and fast-growing outer north-eastern suburbs. During the Whitlam years Casey was the classic "litmus" seat, where Whitlam's appeal to suburban voters on issues like schools and sewerage had the greatest impact. Since the 1980s, however, this area has become increasingly wealthy, and voters are more concerned about interest rates - Casey has among the highest levels of traditional families with children, and of people paying mortgages, of any electorate. Casey also has the highest level of people working in manufacturing and construction (35.9%) of any seat in Australia. The Liberals dominate in the more heavily suburban parts of the seat around Lilydale and Mooroolbark, while Labor retains some strength in the Dandenong Ranges part of the seat.

    Tony Smith won Casey for the Liberals in 2001. He was a parliamentary secretary in the last year of the Howard Government, and was on the opposition front bench from 2007 and 2009. In August 2015 he was elected Speaker after the resignation of Bronwyn Bishop, and successfully restored the standing of the speakership after her inglorious departure. Smith retired at the 2022 election.

    The 2018 redistribution removed Croydon, a strongly Liberal suburb, while adding Labor-inclined Belgrave and Upwey. These changes made Casey a more marginal seat, but it would still require a substantial swing to Labor in Victoria for the Liberals to be in danger. The 2024 redistribution has made only minor changes.

    Aaron Violi, Liberal MP for Casey since 2022, was a manager with a food services company and a former staffer to Senator James Patterson before his election. He has an MBA from La Trobe University.
