from Wikipedia

The Division of Casey is an Australian electoral division in the state of Victoria. The division was created in 1969 and is named for Richard Casey, who was Governor-General of Australia 1965–69.

Key Information

The division is located in the outer eastern suburbs of Melbourne and extends into the Yarra Valley and Dandenong Ranges. As of 2025, it covers the entire Shire of Yarra Ranges, with very small portions of Shire of Cardinia, City of Manningham and Shire of Nillumbik.

The current Member for Casey, since the 2022 federal election, is Aaron Violi, a member of the Liberal Party of Australia. His immediate predecessor is Tony Smith, who was Speaker of the House from 2015 through 2021, and was, after Bob Halverson, the second member for this electorate to occupy the chair.

Geography

[edit]

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]

When it was created in 1968, the division spanned from Wantirna and Bayswater in the eastern suburbs of Melbourne to the south, to Kinglake in the Yarra Valley to the north. It also included the suburbs of Mitcham, Heathmont, Ringwood and Chirnside Park, and the towns of Warrandyte, Kangaroo Ground and Yarra Glen, but stoppping short of Healesville.[2] The areas in eastern Melbourne were previously part of the Division of La Trobe and the areas in the Yarra Valley were previous part of the Division of Deakin.

In 1977, the division was doubled in area size by expanding eastwards and including more of the Yarra Valley, but losing Mitcham, Heathmont and Wantirna to the Division of Deakin. The expanded areas in the Yarra Valley were previously in the Division of La Trobe and the expanded areas included Lilydale, Healsville and Marysville. This expansion was largely reversed in 1984, except Lilydale which remained with Casey, and the lost areas became part of the new Division of Streeton. In 1989, when Streeton was abolished, the division of Casey was expanded eastwards again and regained Healsville, but also gaining Warburton and Yarra Junction. It also included all of Shire of Upper Yarra, extending into national parks and stopping short of Mount Baw Baw and Thomson Dam in Gippsland. In 1994, this expansion was reversed again. However, the division also shifted south, losing almost all areas in the Yarra Valley, but gaining areas to the south such as Kilsyth and the Dandenong Ranges including Mount Dandenong and Monbulk. The division then remained like this until 2010 with only very minor boundary changes in 2003.[2]

In 2010, the division expanded into the Yarra Valley again and regaining Yarra Glen, Healesville, Yarra Junction and Warburton, but lost Croydon in eastern Melbourne to the Division of Deakin. In 2018, it expanded further south to include the remaining areas of Shire of Yarra Ranges previously in the Division of La Trobe, such as Belgrave and Narre Warren East. The division also became co-extensive with the Shire of Yarra Ranges. In 2021, it included the Shire of Cardinia towns of Clematis and Avonsleigh to the south, which was also previously in the Division of La Trobe. In 2024, it was slightly expanded to its north-west into the City of Manningham and Shire of Nillumbik to include Wonga Park and Christmas Hills. These were previously part of the Division of Menzies and Division of McEwen respectively.[2]

As of the 2024 redistribution, it covers an area of approximately 2,624 square kilometres (1,013 sq mi). It covers all of the Shire of Yarra Ranges, with very small portions of Shire of Cardinia (Clematis and Avonsleigh), City of Manningham (Wonga Park) and Shire of Nillumbik (Christmas Hills).[3] Major suburbs and towns include Avonsleigh, Belgrave, Belgrave Heights, Belgrave South, Chirnside Park, Christmas Hills, Clematis, Coldstream, Dixons Creek, Don Valley, Ferny Creek, Gladysdale, Gruyere, Healesville, Hoddles Creek, Kallista, Kalorama, Kilsyth, Kilsyth South, Launching Place, Lilydale, Lysterfield, Menzies Creek, Millgrove, Monbulk, Montrose, Mooroolbark, Mount Evelyn, Mount Dandenong, Olinda, Powelltown, Reefton, Sassafras, Selby, Seville, Seville East, Silvan, Tecoma, Upwey, Wandin, Wandin East, Warburton, Wesburn, Woori Yallock, Wonga Park, Yarra Glen, and Yellingbo.[4]

History

[edit]
Richard Casey, the division's namesake

When it was created it was a highly marginal seat, and at the 1972 federal election it was regarded as the "litmus seat", which the Australian Labor Party had to win to gain government. Lost when the Liberals won in 1975, Labor picked it up again when Labor regained government in 1983. However, a redistribution ahead of the following year's election made Casey marginally Liberal. The Liberals retook the seat in that election and have held it since then. Demographic changes have also contributed in making Casey a fairly safe seat for the Liberal Party, although a redistribution ahead of the 2013 federal election pushed the seat further north into the upper Yarra Valley, estimated to halve the Liberal two-party preferred majority of 4.2 per cent.[5]

Prominent members to have represented Casey include Peter Howson, who served as a minister in the McMahon government; Bob Halverson, who was Speaker of the House of Representatives 1996–98; Michael Wooldridge, who served as Minister for Health in the first five years of the Howard government (1996–2001); and Tony Smith, Speaker from 2015 until 2021.[5]

Boundaries and Composition

The Division of Casey encompasses 2,624 square kilometres in north-eastern Victoria, extending from the outer metropolitan suburbs of into rural areas of the Yarra Valley. Its boundaries include portions of four local government areas: Cardinia Shire Council, Manningham City Council, Nillumbik Shire Council, and Council. Following the 2023 redistribution, the division's boundaries were redrawn to reflect population shifts and were gazetted on 17 October 2024, taking effect for the 2025 federal election. Compositionally, Casey blends rapidly expanding suburban precincts in its northern reaches with semi-rural and agricultural lands to the east and south. Northern areas feature growth corridors around localities such as Whittlesea and , accommodating residential development amid proximity to Melbourne's urban fringe. In contrast, the eastern extent incorporates the Yarra Valley's horticultural and tourism-oriented towns, including Healesville, Yarra Glen, , and . Southern inclusions extend to parts near Emerald in Cardinia Shire, contributing forested and peri-urban elements, while northern and western fringes border divisions like Nicholls and Scullin, incorporating localities such as Panton Hill, Kangaroo Ground, Launching Place, Woori Yallock, and Diamond Creek environs. This diverse geographical makeup supports a voter base spanning commuter suburbs, established townships, and rural holdings, with no single provincial city dominating enrolments.

History

Establishment and Naming

The Division of Casey was established on 20 November as part of a periodic redistribution of federal electoral boundaries in to reflect population changes and ensure equitable representation. This followed the Australian Electoral Commission's determination of new divisions for the state of Victoria, with Casey's first election held in 1969. The creation addressed growth in outer metropolitan and semi-rural areas east of , incorporating suburbs and districts previously aligned with other electorates. The division is named in honour of Lord Richard Gavin Gardiner Casey (1890–1976), a prominent Australian statesman who served as from 1965 to 1969. Casey, elevated to the peerage as Baron Casey of Berwick, had a distinguished career including terms as a Member of the for the Division of La Trobe from 1931 to 1940 and 1949 to 1960, as well as roles as Minister for External Affairs and Governor of Bengal during . His contributions to Australian diplomacy, engineering, and public service, including military honours such as the and from , underscored the rationale for commemorating him through an electoral division in his home state. The naming reflects a tradition of honouring significant figures in Australian governance, particularly those with ties to Victoria.

Electoral Shifts and Boundary Redistributions

The Division of Casey has undergone periodic boundary redistributions since its establishment in 1969, in accordance with the Commonwealth Electoral Act 1918, which mandates reviews to account for shifts in population and enrolment quotas ensuring approximate electoral equality across divisions. These adjustments have generally expanded the division's footprint in Melbourne's outer eastern growth corridors, incorporating developing suburbs and semi-rural areas in the Yarra Ranges and Cardinia local government areas to balance enrolment numbers. The 2023–2024 Victorian federal redistribution, triggered by the state's reduced entitlement from 39 to 38 seats following the 2022 determination under section 24 of the Australian Constitution, significantly altered Casey's boundaries among 34 affected divisions, with the abolition of the Division of Higgins redistributing its enrolments. Finalized on 5 September 2024, the changes expanded Casey to include additional townships and rural localities previously aligned with neighboring electorates such as Indi and McEwen, enhancing its notional Liberal margin post-redistribution while maintaining its status as a contestable outer-metropolitan seat. Electorally, Casey has exhibited volatility in early contests but stabilized as a Liberal-leaning marginal seat since 1984, with incumbents retaining it through successive elections despite two-party-preferred margins often below 5% amid swings tied to national trends in outer suburban voting patterns. The 2022 election saw Liberal candidate Aaron Violi secure victory with a reduced margin following the retirement of long-serving MP Tony Smith, reflecting localized resistance to the national anti-Liberal swing. Boundary expansions in the 2024 redistribution are projected to modestly bolster the Liberal position by incorporating more conservatively inclined rural and fringe enrolments, though the seat remains vulnerable to demographic growth in mortgage-stressed newer suburbs.

Elections and Political Dynamics

Historical Results

The Division of Casey was created for the 1969 federal election and initially won by the Liberal Party's . The seat changed hands multiple times in its early decades, reflecting its marginal status: Labor gained it in 1972, Liberals recaptured it in 1975, Labor won again in 1983, and Liberals secured it in 1984. Since 1984, the Liberal Party has consistently held the division through subsequent elections, including narrow retentions amid national swings against the in 1993, 1998, and 2007. This Liberal dominance persisted despite boundary changes and demographic shifts in the electorate's outer eastern suburbs, with the party benefiting from strong primary vote support in semi-rural and mortgage-belt areas. In the 2019 election, Liberal incumbent Tony Smith secured re-election with a two-party-preferred margin of approximately 4.2%. Smith retired ahead of the 2022 election, but Liberal candidate Aaron Violi retained the seat against a national tide favoring Labor, underscoring Casey's resilience as a Liberal-leaning marginal.

Recent Elections and Marginality Factors

In the held on 21 May 2022, Liberal candidate Violi succeeded retiring MP Tony Smith, securing victory with a two-party-preferred (TPP) margin of 4.6% against Labor's Bill . Violi received 52.3% of the TPP vote, reflecting a slight swing to Labor of 1.6% from the 2019 result, amid a national shift that saw the lose government. Primary vote shares showed Liberals at 42.5%, Labor at 32.4%, Greens at 13.8%, and independents capturing notable support in parts of the electorate. The 2025 federal election, conducted on 3 May 2025, saw Violi retain the seat for the Liberals against Labor challenger Naomi Oakley, maintaining its status as a Liberal hold despite a competitive national contest. Final TPP results confirmed a Liberal margin of approximately 3.8%, narrowed by a 0.8% swing to Labor, influenced by local campaigns emphasizing cost-of-living pressures and infrastructure delivery. stood at 94.5% of enrolled electors, with primary votes distributed as Liberals 41.2%, Labor 33.1%, and Greens rising to 14.5%, underscoring persistent fragmentation beyond the major parties. Casey's marginality arises from its demographic mosaic: a blend of outer-eastern suburbs with high mortgage stress and family-oriented voters sensitive to fluctuations and costs, juxtaposed against more conservative semi-rural enclaves. Rapid in areas like the Yarra Valley foothills and new estates has introduced younger, aspirational households prone to swinging on economic sentiment, as evidenced by consistent TPP margins under 5% since 2001. Boundary redistributions, such as the 2021 adjustments adding growth corridors, have further amplified volatility by balancing Liberal heartlands with Labor-leaning fringes. Local issues, including on EastLink and flood resilience, often amplify national trends, rendering the division vulnerable to modest uniform swings exceeding 2-3%.
