Largest suburbs in South Australia

1. 1

   Mount Gambier, SA

   Population 25,591 · Median income $1,197/wk · SEIFA 887

   Mount Gambier is the largest city in regional South Australia, built on the slopes of a dormant volcano about 450 kilometres south-east of Adelaide and close to the Victorian border. It is famous for the crater lakes that fill its old volcanic vents — above all the Blue Lake, which turns an intense cobalt each summer — together with limestone caves and the terraced gardens of the Umpherston Sinkhole. The surrounding Limestone Coast supports forestry, farming and a steady tourist trade. The area is the Country of the Boandik (Bungandidj) people, who know the mountain as Berrin and the Blue Lake as Warwar; the European name honours the British admiral Lord Gambier, after the peak was sighted from the sea in 1800.

   Morphett Vale, SA

   Population 24,002 · Median income $1,199/wk · SEIFA 894

   Morphett Vale is a southern suburb of Adelaide within the City of Onkaparinga, and is the most populous suburb in South Australia. It is bordered roughly by Sheriffs and Pimpala Roads, Panalatinga Road, Doctors and Beach Roads and the Southern Expressway. Often described as the first major town south of Adelaide, it grew from a subdivision laid out in October 1840 under the name Dublin, and was later named after John Morphett, an early colonist and parliamentarian. The young town soon had churches and chapels, a brewery, a wind-powered flour mill, a court house and a police station, while the surrounding land carried cereal crops, mixed farms and vineyards; a visitor in 1866 noted its neat residences and fine vineyards. A district council was formed in 1852 and merged with Noarlunga in 1932, and during the Second World War the area was a notable producer of flax. The Willunga railway line ran through the town until 1969 and its route now serves as a walking and cycling path. Extensive subdivision through the 1960s turned the district from farmland into a metropolitan suburb, though the heritage-listed old court house and early churches in William Street still recall its colonial beginnings.

3. 3

   Parafield Gardens, SA

   Population 18,467 · Median income $1,384/wk · SEIFA 884

   Parafield Gardens is a largely residential suburb of Adelaide, with a small pocket of industrial land in its south-west corner and a couple of modest shopping centres. It began as a colonial subdivision in the Hundred of Yatala, on land south of the Little Para River. A government plan to place a general cemetery here in the 1880s was abandoned, and the land was instead worked as an experimental farm and then, from 1911, as a poultry enterprise known as Parafield Farm. Residential blocks were first offered in 1958, and from the 1970s the South Australian Housing Trust built widely across the area, with the name Parafield Gardens formally adopted over the following decades and the Pine Lakes Estate added in the early 2000s. The suburb is well supplied with schools — six in all, among them Parafield Gardens High School, which opened in 1976 — and sits within easy reach of the Salisbury Highway.

4. 4

   Mount Barker (SA), SA

   Population 18,330 · Median income $1,624/wk · SEIFA 988

   Mount Barker is a fast-growing town in the Adelaide Hills, about 33 kilometres south-east of Adelaide and named after the peak beside it. That hill honours Captain Collet Barker, who surveyed the area in 1831; the township was laid out in 1839 and farming took hold through the 1840s. The surrounding ranges are the country of the Peramangk people, and the mountain's summit holds particular significance in the region's Aboriginal heritage. Once a quiet farming centre — and the place where the agricultural value of subterranean clover was first recognised — Mount Barker is now among the fastest-growing parts of the state. Heritage steam trains still run on the SteamRanger line, and the Ukaria Cultural Centre draws audiences for chamber music.

5. 5

   Adelaide, SA

   Population 18,202 · Median income $1,365/wk · SEIFA 1045

   Adelaide's city centre occupies the Kaurna lands on the plains between the Mount Lofty Ranges and Gulf St Vincent. The Kaurna people know the area around the centre and Park Lands as Tarndanya, often translated as male red kangaroo rock. Laid out from 1836 by Colonel William Light, the square-mile grid is wrapped entirely in parklands and was the heart of a colony settled by free migrants rather than convicts. South Australia's capital is nicknamed the City of Churches and is famous for the Adelaide Fringe, among the largest arts festivals in the world. North Terrace lines up the state's major museums and galleries, while the Central Market anchors its food culture.

6. 6

   Paralowie, SA

   Population 17,504 · Median income $1,479/wk · SEIFA 880

   Paralowie is a largely residential suburb in Adelaide's northern reaches. It was officially named in 1980, the name said to combine words from Aboriginal languages — 'para', thought to mean river, and 'owie', taken to mean water. European settlement dates from the late nineteenth century, when the land was given over mainly to market gardens and farms; significant growth did not arrive until after the Second World War, with the suburb expanding rapidly from the 1980s through the mid-1990s. Among its heritage landmarks is Paralowie House, a villa on Waterloo Corner Road built in 1894 and listed on the South Australian Heritage Register. It survives as a reminder of the era before Salisbury North was absorbed into metropolitan Adelaide, when the district was still a semi-rural landscape of larger estates. The former farmhouse known as Judd's Homestead, tied to the Burdett family and their cattle stud, is likewise recognised for its heritage value.

7. 7

   Murray Bridge, SA

   Population 15,043 · Median income $1,005/wk · SEIFA 830

   Murray Bridge is the largest river town in South Australia, set on the Murray about an hour east of Adelaide. It is the country of the Ngarrindjeri people, who know the place as Pomberuk. The town grew up around the crossing of the river: a long road bridge opened here in 1879, the first of its kind across the Murray in the colony, and the settlement that gathered at its western end took the bridge's name. Rail, river trade and irrigated farming built the town, and paddle-steamers once worked the wharves. Today Murray Bridge is a busy regional centre, a base for houseboating and fishing on the river, with a riverside precinct, gallery and the long-running speedway.

8. 8

   Prospect (SA), SA

   Population 14,584 · Median income $2,001/wk · SEIFA 1056

   Prospect is an established inner-northern suburb of Adelaide, about five kilometres from the city centre and the seat of the City of Prospect. Its name reaches back to the colony's earliest days: when John Bradford took up a land grant here in 1838 and began dividing it into eight-acre allotments, the gently rising, well-timbered ground gave such a fine outlook over the Adelaide Plains that Colonel William Light is said to have dubbed the fledgling settlement Prospect Village. The council was established in 1872, and in 1944 it formally adopted the same name for the suburb at its heart. Today Prospect is generously supplied with green space, among it the Prospect Oval, the Soldier's Memorial Gardens and the rose-planted St Helens Park.

9. 9

   Port Lincoln, SA

   Population 14,458 · Median income $1,243/wk · SEIFA 915

   Port Lincoln looks out over the broad, sheltered waters of Boston Bay on the Lower Eyre Peninsula, a long drive but short flight west of Adelaide. The Barngarla people are acknowledged as its traditional owners and know the place as Galinyala, said to mean a place of sweet water. Matthew Flinders charted the bay in 1802 and named it after Lincoln in his native English county. Today the city calls itself Australia's seafood capital, home to one of the country's largest fishing fleets and a tuna and aquaculture industry that farms kingfish, abalone, and mussels. Visitors come for the bay, the seafood, shark-cage diving, and the wild coast of nearby Lincoln and Coffin Bay national parks.

10. 10

    Mawson Lakes, SA

    Population 13,794 · Median income $1,940/wk · SEIFA 1029

    Mawson Lakes is a planned northern suburb of Adelaide, about twelve kilometres from the city, built from the late 1990s on the site of a nineteenth-century sheep-breeding run known as 'The Levels'. This is Kaurna country, part of the Adelaide Plains across which the Kaurna people moved their camps with the seasons. The suburb was laid out around two man-made lakes and named after Sir Douglas Mawson, the geologist and Antarctic explorer; the seven-hectare Sir Douglas Mawson Lake is its centrepiece. From 1998 a partnership between the developer Delfin, the State Government and the City of Salisbury shaped a self-contained, mixed-use community of housing, shops and schools, wrapped around a University of South Australia campus and Technology Park Adelaide — opened in 1982 as Australia's first science park.

11. 11

    Hallett Cove, SA

    Population 12,512 · Median income $1,871/wk · SEIFA 1025

    Hallett Cove is a coastal suburb of Adelaide in the City of Marion, about 21 km south of the city centre, set around a small rocky beach where the Field River meets the sea. It is best known for the Hallett Cove Conservation Park, whose clifftops carry glacial striations — scratches worn into the rock that are among Australia's clearest evidence of the Permian glaciation, when this land lay within the ancient supercontinent of Gondwana. The park also holds deep archaeological significance and great cultural significance for the Kaurna people. The suburb takes its name from John Hallett, who is said to have come upon the cove in 1837 while searching for missing stock. Today it is a quiet residential area valued for its coastal walks and remarkable geology.

12. 12

    Happy Valley (SA), SA

    Population 11,420 · Median income $1,573/wk · SEIFA 997

    Happy Valley is a metropolitan suburb in Adelaide's south, about twenty kilometres from the city centre, best known for the Happy Valley Reservoir and the large water-treatment plant beside it, which supplies much of metropolitan Adelaide. Despite being ringed by suburbs, it keeps a semi-rural feel thanks to the native vegetation, parklands and golf courses around the reservoir. The area was originally known by the Kaurna name Warekila, said to mean place of changing winds. Its English name is attributed to Edward Burgess, a Methodist settler who arrived at Holdfast Bay in 1837 and made his home here over the following years; by 1866 Happy Valley was described as a small agricultural settlement, with wheat farming soon joined by wine-grape growing. When the reservoir was built, the original township, school and cemetery were relocated to make way for the water. The name was applied to a subdivision from the late 1950s, and steady growth followed as the metropolitan area expanded southward.

13. 13

    Woodcroft (SA), SA

    Population 11,326 · Median income $1,664/wk · SEIFA 983

    Woodcroft is a residential suburb in Adelaide's southern reaches, about 20 kilometres from the city centre, with Panalatinga Creek threading through it and the Hills Face Zone rising to the east. European settlement dates to 1869, when Robert Wright and his wife Mary built a modest limestone-and-mud cottage on land east of John Reynell's holding at Reynella. In 1897 the vigneron Richard Mostyn Owen established the Mount Hurtle winery and a homestead he called Woodcroft Farm, and it was this property that later gave the suburb its name. The original holdings passed out of family hands in the 1970s and the area was progressively subdivided for housing. Mount Hurtle survives as a boutique winery, and Woodcroft is now a settled suburb of young, home-owning families.

14. 14

    Aberfoyle Park, SA

    Population 11,234 · Median income $1,765/wk · SEIFA 1007

    Aberfoyle Park is a hilly suburb in the Adelaide Hills, within the City of Onkaparinga, about 20 kilometres south of the city centre. In 1845 Christian Sauerbier, a German settler, bought land nearby at Happy Valley, and his family became known for fine stud stock and an orange grove; by 1856 he held eleven sections in the district. During the First World War, as anti-German feeling ran high, his son changed the family name to Aberfoyle, thought to recall the Scottish village where his father had once lived. The farmland was eventually given over to housing, and the suburb of Aberfoyle Park was proclaimed in 1980. It is built around a shopping centre known as The Hub, and is home to Aberfoyle Park High School, one of the largest public secondary schools in South Australia. Several primary schools share a single campus, and the suburb keeps parkland such as Thalassa Park among its hillside streets.

15. 15

    Craigmore, SA

    Population 10,943 · Median income $1,513/wk · SEIFA 906

    Craigmore is a residential suburb on the northern fringe of Adelaide, in the City of Playford near Elizabeth. It lies within the traditional Country of the Kaurna people of the Adelaide Plains. European settlement began in the early 1850s, when the wider district was known as Smithfield after a township established by John Smith. Gavin Scoular took up land here to create Blair Farm, while Thomas Hogarth — later a member of the South Australian Legislative Council — established a neighbouring property called Blair Place around 1850. Many of the district's early settlers came from Scotland, and the suburb's name is thought to combine the Scots words for a rocky hill and for something large. Modern Craigmore took shape from the 1970s with State Housing Trust estates, joined by private developments such as Blair Park from 1975, and successive estates have made it one of Adelaide's longest suburbs from end to end. It is served by Craigmore High School, which opened in 1970, and by Craigmore Park, through which Smith Creek runs.

16. 16

    Seaton (SA), SA

    Population 10,877 · Median income $1,300/wk · SEIFA 938

    Seaton is a residential suburb in Adelaide's west, close to Findon, Grange and West Lakes, and home to the Royal Adelaide Golf Club. The main roads of Tapleys Hill Road and Grange Road run through the area. Before the Second World War the district was largely rural — a patchwork of market gardens, poultry farms and lucerne paddocks bounded to the west by coastal sand dunes. The rapid wartime and post-war expansion of industry nearby, including the munitions works at Hendon and the General Motors-Holden assembly plant at Woodville, prompted the South Australian Housing Trust to build extensive housing for workers across Seaton and its neighbours, and the suburb took on its present settled character. Its first post office opened in 1965, and today Seaton is served by its own primary and high schools.

17. 17

    Salisbury North, SA

    Population 10,683 · Median income $1,068/wk · SEIFA 802

18. 18

    Aldinga Beach, SA

    Population 10,667 · Median income $1,297/wk · SEIFA 925

    Aldinga Beach is an outer southern suburb of Adelaide, lying within the City of Onkaparinga along the coast of the Fleurieu Peninsula. Before British colonisation the area was Country of the Kaurna people, who occupied the Adelaide plains and the western side of the peninsula; the Kaurna name recorded for Aldinga was Ngaltingga. The long sandy beach is a popular spot for swimming, surfing, snorkelling and scuba diving through the summer, and it looks out over the Aldinga Reef Aquatic Reserve, created to protect an unusual nearshore reef formation. Inland, the Aldinga Scrub Conservation Park preserves a remnant of the coastal scrub that once lined this shore, while the nearby Washpool wetland fills with the winter rains to provide important habitat for waterbirds such as the hooded plover. The smaller Silver Sands holiday area adjoins the suburb to the south, and a post office opened here in 1960 as the district settled into a relaxed seaside community.

19. 19

    Golden Grove, SA

    Population 10,299 · Median income $1,669/wk · SEIFA 1016

    Golden Grove is an outer north-eastern suburb of Adelaide in the City of Tea Tree Gully, known for its hilly ground, generous vegetation and closeness to the Adelaide Hills. Captain Adam Robertson settled here after arriving in South Australia in 1839 and gave the district its name — that of the last ship he had commanded — donating land in 1853 for a local school. Freestone was quarried in the area from the earliest settlement days. The modern suburb was built as one of South Australia's large master-planned communities: from 1983 the state's Urban Land Trust engaged the developer Delfin to lay it out, earthworks began in 1985, and the final allotment sold in 2002, completing a project that ran for two decades. Its three secondary schools share a campus near the Grove shopping centre, and the bushland of the Cobbler Creek Recreation Park lies along its edge. Newer subdivisions have continued to add homes into the 2020s.

20. 20

    Flagstaff Hill, SA

    Population 10,184 · Median income $2,080/wk · SEIFA 1047

    Flagstaff Hill is a leafy residential suburb in Adelaide's south, part of the City of Onkaparinga and built around the Sturt Gorge Recreation Park. It takes its name from the hill itself, where Colonel William Light — the surveyor who laid out Adelaide — is said to have raised a flagstaff during his survey of the region in the late 1830s. The mark served as a survey trig point, and by 1842 the locality was simply known as the Flagstaff. Through the nineteenth century the surrounding land was used for farming and grazing. Suburban development began in the 1960s, when estate companies started buying and subdividing the farmland; the first blocks were released for sale in 1967 and sold quickly. A further stage followed from 1985. Today the suburb is prized for its many parks and reserves and its bushland setting along the Sturt Gorge.

    Greenwith, SA

    Population 10,103 · Median income $2,002/wk · SEIFA 1011

22. 22

    Magill, SA

    Population 9,693 · Median income $1,616/wk · SEIFA 1034

    Magill is a foothills suburb about seven kilometres east of central Adelaide, straddling the City of Burnside and the City of Campbelltown near the base of the Mount Lofty Ranges. The Kaurna people, Traditional Owners of the Adelaide Plains, lived here for thousands of years among an open woodland of widely spaced gums. From 1838 the area grew as the Makgill Estate, taken up by two Scotsmen, Robert Cock and William Ferguson, who had met sailing to the new colony aboard HMS Buffalo and named it for Cock's trustee, David Makgill; the spelling softened to Magill in the late 1940s. Among the first of Adelaide's foothill villages to be subdivided, it became a district of vineyards and orchards strung along Magill Road, and it remains home to the historic Penfolds Magill Estate winery and a University of South Australia campus.

23. 23

    Athelstone, SA

    Population 9,601 · Median income $1,941/wk · SEIFA 1037

    Athelstone is a suburb on the north-eastern edge of Adelaide, about 10 km from the city centre in the City of Campbelltown, where the plains meet the foothills of the Adelaide Hills. The River Torrens borders the suburb, and Gorge Road runs west to east through it before climbing towards Kangaroo Creek Dam. The first Europeans known to have passed through were the explorers John Hill and George Imlay, who camped beside the Torrens in 1838 on their way to the Murray. Drawn by the fertile alluvial soils, settlers soon took up farming, and the suburb's name comes from Athelstone house and mill, built by Charles Dinham in the mid-1840s; a later owner converted the mill for grape crushing in 1855. Long a district of orchards and market gardens, Athelstone was largely absorbed into suburban Adelaide only in the second half of the twentieth century, and it remains bordered by the bushland of Black Hill Conservation Park.

24. 24

    Ingle Farm, SA

    Population 9,543 · Median income $1,286/wk · SEIFA 909

    Ingle Farm is a residential suburb in Adelaide's north-east, at the foot of the Mount Lofty Ranges, about 12 kilometres from the city centre. Its story begins with James Rowe, who settled here to farm in the 1840s; the property gained its name after his grandson married Martha Wright, who came from the town of Inglewood, and so the farm became known as Ingle Farm. In 1959 the South Australian Housing Trust bought the Rowe brothers' land and laid out a housing estate, with the first Trust homes built in the mid-1960s. The Rowe name lives on in Rowe Park, beside Ingle Farm Primary School. The suburb's hub is the Ingle Farm Shopping Centre, and frequent buses connect it to the city along the O-Bahn Busway.
