The Division of Hindmarsh is an Australian Electoral Division in South Australia covering the western suburbs of Adelaide. The division was one of the seven established when the former Division of South Australia was split on 2 October 1903, and was first contested at the 1903 election, though on vastly different boundaries. The Division is named after Sir John Hindmarsh, who was Governor of South Australia from 1836 to 1838. The 78 km² seat extends from the coast in the west to South Road in the east, covering the suburbs of Ascot Park, Brooklyn Park, Edwardstown, Fulham, Glenelg, Grange, Henley Beach, Kidman Park, Kurralta Park, Morphettville, Plympton, Richmond, Semaphore Park, Torrensville, West Beach and West Lakes. The Adelaide International Airport is centrally located in the electorate, making noise pollution a prominent local issue, besides the aged care needs of the relatively elderly population − the seat has one of Australia's highest proportions of citizens over the age of 65. Progressive boundary redistributions over many decades transformed Hindmarsh from a safe Labor seat in to a marginal seat often won by the government of the day.
Geography
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.
Though initially based on the greater Port Adelaide area to the north of the present boundary, now represented by the Division of Port Adelaide, Hindmarsh has long been dominated by working-class families and aged pensioners. Redistributions from the late 1940s onward have moved Hindmarsh clear of its initial boundaries over time to include increasingly wealthy seaside suburbs in and around Glenelg and the Holdfast Bay area to the south.
With only the two additional seats of Adelaide and Boothby covering the metropolitan area until 1949, the south-east state border rural seat of Barker was then considered a "hybrid urban-rural" seat, stretching all the way from the southern tip of South Australia at least as far as Glenelg and the Holdfast Bay area, and at times even stretched as far as the western metropolitan suburbs of Keswick and Henley Beach. After 1949 some of the area had variously been covered by Boothby, Kingston and now-abolished Hawker. The present Hindmarsh has changed little geographically since neighbouring Hawker was abolished in 1993, though the north-western coastal strip was added from 2004.
Though now a marginal seat, for nearly a century it had been one of the safest Labor seats in the country, and was in Labor hands for all but three years from the 1903 election to the 1993 election. As a measure of the strength of Labor support at the time, it was the only seat in the state won by Labor in the massive United Australia Party landslide of 1931. One of the few times that Labor's hold on the seat was seriously threatened in this time came in 1966, when the Labor margin was pared down to 1.7 percent. Even then, sitting member Clyde Cameron still won enough primary votes to retain the seat outright.
Prominent members
Prominent members for the electorate have included Norman Makin, who was Speaker in the Scullin government, and a cabinet minister in the Curtin and Chifley governments, and Clyde Cameron, who was a cabinet minister in the Whitlam government.
Later years
A redistribution ahead of the 1984 election made Hindmarsh far less safe for Labor. From then on, successive redistributions gradually gave it a voting pattern similar to mortgage belt seats, which tend to be fairly marginal.
Labor's hold on the seat became even more tenuous in the redistribution prior to the 1993 election when it absorbed most of the area around Holdfast Bay that had previously been in abolished Hawker. This reduced Labor's two-party margin from an already marginal 5.3 percent to a paper-thin one percent. Combined with state-level anger at the time stemming from the State Bank Collapse, this was enough for Liberal Chris Gallus, previously the member for Hawker, to win the seat in 1993 with a one percent two-party margin from a two percent two-party swing, becoming only the second non-Labor MP ever to win it. She seemingly consolidated her hold on the seat at the 1996 election amid her party's large victory that year, increasing her margin to 8.1 percent – easily the strongest result for a non-Labor candidate in the seat's history.
