Where People Are Moving To In South Australia In 2026

South Australia's population growth is increasingly concentrated on the edges of Adelaide and in a handful of fast-growing regional centres. In the latest Australian Bureau of Statistics estimates, covering the 2024-25 financial year, Greater Adelaide added 18,600 people, while the rest of South Australia added another 1,900. Yet Adelaide itself recorded a net internal migration loss of 2,425 people, showing that population growth is not the same thing as attracting residents from elsewhere in Australia. The clearest movement is toward new housing corridors on Adelaide's northern fringe, with additional growth in the Adelaide Hills and regional centres connected to the capital by major roads. Munno Para West-Angle Vale recorded a net internal migration gain of about 2,000 people in 2024-25, the largest in South Australia. Longer-term state projections point in the same direction. The Outer North is projected to be Greater Adelaide's fastest-growing sub-region through 2041, while Mount Barker, Murray Bridge, and the Fleurieu are also expected to expand.

Munno Para West-Angle Vale

This suburb is the strongest example of South Australians moving toward a new outer-suburban growth corridor. Its population increased by about 2,400 people in 2024-25, an 11% increase. More importantly for a migration-focused story, the area recorded a net internal migration gain of approximately 2,000 people, alongside a natural increase of 390. That makes internal movement the dominant identifiable component of its growth, rather than population gains being explained primarily by overseas migration.

The area sits within Adelaide's expanding northern development belt, where new greenfield housing is providing an alternative to established suburbs with less available land. PlanSA's longer-term projections reinforce the scale of the shift. Munno Para West-Angle Vale is projected to record the largest population increase of any South Australian SA2 between 2021 and 2041, with more than 35,000 additional residents under the medium projection.

The physical change is substantial. New residential estates are extending toward Angle Vale and surrounding communities, while transport investment is being planned around the area's rapid growth. The Curtis Road level-crossing project is one example of infrastructure being upgraded to accommodate the expanding northern population.

Virginia-Waterloo Corner

This region had South Australia's fastest population growth rate in 2024-25. Its population increased by about 1,300 residents, equivalent to 17% growth in a single year. That placed it ahead of Munno Para West-Angle Vale and Mount Barker on percentage growth, although its smaller population means its absolute increase was lower.

Its importance to the migration story comes from its position inside Adelaide's northern expansion zone. The area includes the corridor around Virginia, Waterloo Corner, and the broader Northern Plains, where residential development is occurring alongside an established agricultural and food-production economy. PlanSA's local projections specifically identify the Virginia-Waterloo Corner SA2 as one of the state's major future growth areas, with the Riverlea development included in its boundaries.

The area's growth is therefore closely tied to the availability of new housing rather than the redevelopment of an established inner suburb. Riverlea alone is planned as a major new community, while surrounding Two Wells and Roseworthy are also expected to accommodate additional residents. PlanSA's projections show that Adelaide's Outer North is expected to grow by roughly 90,000 people between 2021 and 2041, an average annual increase of more than 3%.

Mount Barker

This city added about 1,200 residents in 2024-25, giving it the third-largest population increase among South Australia's individual SA2 areas after Munno Para West-Angle Vale and Virginia-Waterloo Corner. The area's population grew by roughly 3.2% during the year, continuing a longer pattern of expansion in the Adelaide Hills.

The migration story here is tied to the area's role as a major growth centre outside Adelaide's established metropolitan footprint. New housing supply has allowed people to move into the Hills while remaining within commuting distance of Adelaide. PlanSA projects the Adelaide Hills sub-region to grow from about 80,500 people in 2021 to more than 108,000 by 2041, an average annual growth rate of 1.73%. Mount Barker SA2 itself is projected to add just over 20,000 residents over the same period, making it the second-largest projected-growing SA2 in the state.

That expansion is visible in the town's development pattern. New residential areas are spreading around Greater Mount Barker while the town centre is being expanded to serve a substantially larger population. The result is a place absorbing both people relocating from elsewhere in South Australia and families moving into newly constructed housing.

Lewiston-Two Wells

This region recorded 5% population growth in 2024-25, placing it among the fastest-growing SA2s in South Australia. While its increase was smaller in absolute terms than Munno Para West-Angle Vale or Virginia-Waterloo Corner, the rate is significant for a comparatively small community and fits the broader movement toward Adelaide's northern fringe.

The area's appeal is fundamentally connected to housing supply and proximity to Adelaide. Two Wells is positioned north of the metropolitan area but remains connected to Adelaide through the major road network, while large areas of developable land are available for new residential communities. The town is also part of the wider northern growth system that includes Virginia, Angle Vale and Roseworthy.

PlanSA's projections identify the Northern Plains & Barossa as one of South Australia's faster-growing planning regions, with the region projected to rise from about 38,800 residents in 2021 to nearly 50,900 by 2041.

The significance of Lewiston-Two Wells is that it illustrates how population growth is spreading beyond Adelaide's formal metropolitan core. Instead of concentrating entirely in established suburbs, new residents are being accommodated in smaller communities where greenfield land can support detached housing and larger development.

Adelaide Plains

This region stands out as one of South Australia's strongest regional growth areas in the latest data. Its population increased from about 11,307 in 2024 to 11,736 in 2025, a 3.8% increase. That was the sixth-fastest growth rate among Australia's regional local government areas in the latest Regional Australia Institute analysis of ABS population data.

The area also fits the broader internal-migration pattern. The Regional Movers Index continues to identify Adelaide Plains among the South Australian regional destinations receiving people moving beyond the capital-city footprint. The area's position immediately north of Adelaide gives it a different migration profile from remote regional towns. Residents can trade some metropolitan density for more housing space while remaining connected to the capital.

Housing development is an important part of the equation. Two Wells and nearby communities are receiving new residential investment, while the Northern Plains remain a major employment area for agricultural, food production, and related industries. The combination of available land, proximity to Adelaide and continued infrastructure investment gives the region room to absorb additional residents.

Murray Bridge

This region is one of the strongest longer-term growth stories outside metropolitan Adelaide. PlanSA projects the Murray Bridge sub-region to increase from 22,689 residents in 2021 to 31,935 by 2041, an increase of more than 9,200 people. That represents an average annual growth rate of 2.04%, considerably faster than the projected 0.48% annual growth rate for Country South Australia overall.

Internal migration has been an important part of Murray Bridge's recent growth story. The Regional Movers Index has previously identified the city as a significant destination for people moving from capital cities and other regional areas, while its position on the South Eastern Freeway makes it one of the regional centres most closely connected to Adelaide.

The housing pipeline is unusually large for a regional South Australian centre. The proposed Gifford Hill development is planned as a major master-planned community south of Murray Bridge, while state planning documents identify the wider Murray Bridge area for substantial future housing growth. That development capacity is important because it gives the city a mechanism for absorbing newcomers rather than relying only on turnover in existing housing.

The Shape of South Australia's Growth

South Australia's 2026 population story is less about people abandoning Adelaide than about where within and around the Adelaide region new residents are settling. Adelaide's overall population continues to grow, but its negative internal-migration balance shows that some residents are moving elsewhere while overseas migration supplies much of the capital's increase. The strongest internal-growth signal is on the northern edge, particularly Munno Para West-Angle Vale, Virginia-Waterloo Corner, Two Wells and the wider Adelaide Plains, with Mount Barker and Murray Bridge providing major alternatives outside the established metropolitan area.

That pattern has consequences for South Australians already living in these communities. More residents mean greater demand for roads, schools, utilities, and housing, while the areas with the biggest land releases will continue to experience the fastest physical change. PlanSA's projections suggest the shift is not a short-term blip. The Outer North is expected to be South Australia's fastest-growing Adelaide sub-region through 2041, with continued expansion also projected around Mount Barker, Murray Bridge, and the Fleurieu.
