    Division of Aston

    Aston was created in 1984, in Melbourne's eastern suburbs, centred on the fast-growing City of Knox and new wealthy areas such as Wantirna and Lysterfield. It has a very high proportion of families with dependent children and dwellings being purchased, indications of traditional families paying high mortgages. This is a high-income mortgage belt seat, without the high concentration of people in professional occupations that marks wealthy seats closer to the city centre. These factors explain why Aston changed from a marginal seat in the 1980s to the safest Liberal seat in metropolitan Melbourne in 2004. There are still a few Labor-voting areas around Boronia on the north-eastern edge of the seat. The seat's boundaries have not been affected by the 2021 redistribution.

    Aston's first member, John Saunderson (Labor - he had previously been member for Deakin from 1983 to 1984) was defeated in 1990 by Peter Nugent (Liberal), and the seat has got steadily better for the Liberals since. Nugent died in 2001 and was succeeded by Chris Pearce, who easily held the seat until he retired in 2010.

    Alan Tudge, Liberal MP for Aston from 2010 to 2023, was a lawyer, consultant and ministerial adviser (to Alexander Downer) before his election. He became a parliamentary secretary in 2013 and Minister for Minister for Cities, Urban Infrastructure and Population in 2018. He joined the Cabinet in 2019 and became Minister for Education and Youth. In December 2021 he resigned after allegations of domestic violence, which he denied.

    In March 2023 Tudge resigned from Parliament. The subsequent by-election was won by Labor's Mary Doyle, an organiser with the National Tertiary Education Union, with a 7.4% swing to Labor. This was the first time since 1921 that an incumbent government had taken an opposition seat at a by-election. Aston has been only slightly altered by the 2024 redistribution. The Liberal candidate is Manny Cicchiello, a school Deputy Principal and former Mayor of Knox.
