Largs Bay

A $1,070,000 median house price in a suburb that sits at SEIFA IRSAD decile 5 tells you something unusual is happening at Largs Bay.

Population is 4,104 across just 2.08 km2, giving a density of 1,976 per km2. The resident base is aging, with a median age of 46, which is 6 years above the national figure, and 83.9% of residents stayed put between census periods, signalling deep attachment to the location.

The median house price reached $1,070,000 in 1Q 2026, up from $850,250 a year earlier, a 25.8% gain in 12 months. Separate houses dominate at 82.6% of stock, with apartments at only 10.8% and semi-detached at 6.4%, so buyers face a tight detached-house market. Three-bedroom dwellings account for 51.8% of homes, with 4-plus bedrooms at 23.9%, suiting families rather than smaller households. Monthly mortgage repayments average $1,800, giving a mortgage-to-income ratio of 22.0%, below the 30% stress threshold, which means buyers at median income can service median debt without strain. Outright owners at 35.0% and mortgage holders at 44.0% together make up nearly 80% of residents, indicating an owner-occupier dominated market with relatively low renter turnover.

For Buyers

The median house price reached $1,070,000 in 1Q 2026, up from $850,250 a year earlier, a 25.8% gain in 12 months. Separate houses dominate at 82.6% of stock, with apartments at only 10.8% and semi-detached at 6.4%, so buyers face a tight detached-house market. Three-bedroom dwellings account for 51.8% of homes, with 4-plus bedrooms at 23.9%, suiting families rather than smaller households. Monthly mortgage repayments average $1,800, giving a mortgage-to-income ratio of 22.0%, below the 30% stress threshold, which means buyers at median income can service median debt without strain. Outright owners at 35.0% and mortgage holders at 44.0% together make up nearly 80% of residents, indicating an owner-occupier dominated market with relatively low renter turnover.

For Investors

The renter share is 20.9%, below state and national averages, which limits the available tenant pool relative to the purchase price of $1,070,000. Weekly rent of $315 implies a gross yield of approximately 1.5%, low for a mid-decile SA suburb. Vacancy sits at 8.0%, elevated compared to Adelaide metro norms, suggesting some softness in rental demand or seasonal holiday letting patterns given the coastal location. Development activity is active with 62 applications in the past 12 months, covering dwelling additions, pools and one industrial replacement, reflecting an established suburb where renovation rather than new supply drives activity. Net overseas migration of 145 per year is the primary population driver, which supports long-term housing demand, though the 0.46% annual growth rate is slow compared to greenfield corridors.

Tenure splits show 35.0% own outright, 44.0% carry a mortgage and 20.9% rent, an owner-occupier weighting that is higher than national norms. The 8.0% vacancy rate is elevated and worth watching for investors. Stock is overwhelmingly detached at 82.6%, with apartments at 10.8% and semi-detached at 6.4%. Bedroom distribution centres on three-bedroom homes (51.8%), with 4-plus at 23.9% and two-bedroom at 21.5%. The price moved from $850,250 in 1Q 2025 to $1,070,000 in 1Q 2026, a 25.8% rise in one year, which is exceptional compared to SA state-wide price trends. Rent-to-income at 16.7% and mortgage-to-income at 22.0% both sit below stress thresholds, indicating the existing resident base is financially stable relative to housing costs.

Transport to Work

Car dependence is high at 84.4% of commuters driving, above national averages, while only 7.4% use public transport and 3.0% walk or cycle. This reflects the suburban coastal layout and limited transit options compared to inner Adelaide. The IRSAD decile of 5 places the suburb at the national median on the combined advantage-disadvantage index, while the IEO decile of 6 for education and occupation is modestly above average. Crime totals 282 incidents, giving a rate of 68.7 per 1,000 residents, which requires comparison against SA state averages to contextualise accurately; no granular category breakdown is available. No schools are recorded inside the suburb boundary, so families rely on nearby institutions. The 18.3% volunteering rate and stable 83.9% residential retention suggest strong community cohesion.

Population Forecast

+0.46%/yr

(+72 people/yr)

Established

Population growth tracks at 0.46% annually, adding roughly 72 people per year to the current 4,104. The 10-year change was 2.1%, placing Largs Bay among slow-growth established suburbs rather than growth corridors. Medium forecasts for the broader SA2 area project gradual increases to 2031. Overseas migration is the primary driver at 145 net arrivals per year, above internal migration of 66, reflecting Adelaide's growing international intake. The gentrification score is 19 (not gentrifying), which makes sense for a suburb already with a $1,070,000 median, suggesting prices reflect location value rather than a transitional upgrade cycle. Rent grew 23.1% over the period and real income grew 15.7%, meaning rents are outpacing wages, a tension for future affordability.

Is Largs Bay safe?

Recorded crime totals 282 incidents, giving a rate of 68.7 per 1,000 residents. No category breakdown is available to compare against SA state averages. Indirectly, the 83.9% residential retention rate and 18.3% volunteering rate suggest a stable and engaged community, which tends to correlate with lower crime risk.

Is Largs Bay good for property investment?

The 25.8% price gain from $850,250 to $1,070,000 in one year is strong capital growth. However, the rental yield is low at approximately 1.5% on a $315 weekly rent, and the 8.0% vacancy rate is elevated compared to metro Adelaide norms. Renter share of 20.9% is below average, limiting the tenant pool. Overseas migration of 145 per year supports long-term demand.

How is Largs Bay's population changing?

Population grows at 0.46% per year, adding about 72 residents annually to the current 4,104. The 10-year change was 2.1%, classifying Largs Bay as a slow-growth established suburb. Overseas migration at 145 net arrivals per year is the primary driver. The profile is aging, with the senior share up 4.7 points over the decade.

How much development is happening in Largs Bay?

There were 62 development applications lodged in the past 12 months. Approvals include dwelling additions, pool and safety fence installations, and one industrial tank replacement, consistent with an established suburb where owners improve rather than redevelop. No new residential unit supply is evident in recent approvals.

How to read these comparisons

Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.

Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.

Data sources: ABS 2021 Census (demographics, income, tenure), state Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
