Collinswood
With a median house price of $1,850,000 and a university qualification rate of 55.3%, Collinswood packs significant demographic weight into just 0.52 square kilometres. Household income sits at the 72.1st percentile nationally, yet 43% of residents rent rather than own, an unusually high share for a premium suburb. The workforce is dominated by Professionals (290 workers) and skews heavily toward Healthcare (25.6%) and Education (12.1%). At 32.8% overseas-born, the suburb sits 11.2 percentage points above the national figure, making it one of inner Adelaide's more internationally mixed pockets.

Median 1Q 2026
The $1,850,000 median house price in 1Q 2026 represents a 12.6% fall from the $2,116,250 peak in 1Q 2025, giving buyers a notable entry point below recent highs. Housing stock is more varied than most premium suburbs: 46.6% are separate houses, 31.0% semi-detached and 22.4% apartments. Two-bedroom dwellings dominate at 43.8%, with three-bedroom at 30.1% and four-plus at 19.9%. Monthly mortgage repayments average $2,077, producing a mortgage-to-income ratio of 24.9%, below the 30% stress threshold despite household incomes at the 72.1st percentile nationally. Only 26.5% own outright, compared to the typical owner-occupier suburb, signalling that many residents are in the earlier stages of wealth accumulation.

Only 26.5% own outright, compared to the typical owner-occupier suburb, signalling that many residents are in the earlier stages of wealth accumulation.
For Investors
A 43.0% renter share gives landlords a broad tenant pool, and weekly rent of $300 reflects the stock's two-bedroom-dominant profile. Vacancy sits at 7.6%, above the 3% equilibrium level, suggesting current oversupply in the rental market relative to demand. Development activity is steady at 22 applications in the past 12 months, including multi-dwelling projects such as three two-storey detached dwellings approved in 1Q 2026. The 12.6% price correction from peak means yields have improved compared to mid-2025, though the absolute $300 weekly rent against the $1,850,000 median still implies a gross yield below 1%. Rental demand is supported by the high overseas-born share at 32.8% and the suburb's proximity to inner-Adelaide employment hubs.

Tenure
Tenure divides unevenly: 43.0% rent, 30.6% carry a mortgage and only 26.5% own outright, a pattern consistent with a younger, mobile population in a high-priced market. The stock splits across 46.6% separate houses, 31.0% semi-detached and 22.4% apartments, offering more variety than comparable premium suburbs. Two-bedroom dwellings make up 43.8% of stock, the largest segment, with three-bedroom at 30.1% and four-plus at 19.9%. The median house price fell from $2,116,250 in 1Q 2025 to $1,850,000 in 1Q 2026, a 12.6% decline. Rent-to-income at 15.6% remains well below stress levels, and mortgage-to-income at 24.9% stays below the 30% threshold, so financial pressure on residents is currently limited despite the premium price point.

Transport to Work
Car dependence is high at 81.4% of commuters, above the inner-Adelaide average, with public transport at 8.8% and walking or cycling at 4.4%. No schools are recorded within the 0.52 square kilometre boundary, so families access institutions in neighbouring suburbs. The crime rate of 28.7 incidents per 1,000 residents covers 43 total recorded offences, a relatively low absolute count for an inner suburb. Rent-to-income at 15.6% and mortgage-to-income at 24.9% both sit comfortably below stress thresholds, so financial liveability is strong compared to many premium markets. Need-for-assistance rates are low at 4.5% (64 residents), and the 18.0% volunteering rate reflects an engaged, professionally employed population concentrated in Healthcare and Education sectors.

Is Collinswood good for property investment?
The 43.0% renter share is well above the national average, providing a deep tenant pool. However, the 7.6% vacancy rate is above equilibrium, and gross yield against the $1,850,000 median at $300 weekly rent is below 1%. The 12.6% price correction from peak may offer a more attractive entry point compared to 2025 levels.
How is Collinswood's population changing?
Collinswood's 1,496 residents occupy just 0.52 square kilometres at a density of 2,856 per km2, leaving little room for expansion. The 20.6% turnover rate and 79.4% residential stability rate suggest the population is largely settled, with growth constrained to infill development such as the 22 applications lodged in the past 12 months.

How much development is happening in Collinswood?
There were 22 development applications lodged in the past 12 months, including a performance-assessed approval for 3 two-storey detached dwellings in 1Q 2026. Activity reflects infill densification within a 0.52 square kilometre footprint rather than new greenfield supply.
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.
