SA 5081 Census 2021 + Live DA Data

Collinswood

The suburb is younger than the national profile at a median age of 36, and university attainment is 25.2 percentage points above the national comparison. Household income sits at the 72.1st percentile, supporting the price bracket, although 41.8% of dwellings are rented. Compared with nearby Prospect and Nailsworth, Collinswood's 46.6% separate-house share alongside 31.0% semi-detached and 22.4% apartment stock gives it a more mixed, compact housing pattern. Its 28.7 crimes per 1,000 residents is a useful low-crime signal, but buyers should still assess each street and property.

Prices were 12.6% lower in 1Q 2026 than the 1Q 2025 peak, so negotiation and recent comparable sales matter more than relying on a single headline. Housing choice is broader than the median suggests, with 46.6% separate houses, 31.0% semi-detached homes and 22.4% apartments. Two-bedroom dwellings account for 43.8%, ahead of three-bedroom homes at 30.1%, which may suit singles, couples and smaller households more than growing families. Mortgage costs represent 24.9% of household income, below the stated stress level, while rent is 15.6%, also below stress levels. Compared with nearby Prospect and Nailsworth, inspect lot size, renovation quality and parking carefully because the compact stock mix can produce large price differences.

For Buyers

Prices were 12.6% lower in 1Q 2026 than the 1Q 2025 peak, so negotiation and recent comparable sales matter more than relying on a single headline. Housing choice is broader than the median suggests, with 46.6% separate houses, 31.0% semi-detached homes and 22.4% apartments. Two-bedroom dwellings account for 43.8%, ahead of three-bedroom homes at 30.1%, which may suit singles, couples and smaller households more than growing families. Mortgage costs represent 24.9% of household income, below the stated stress level, while rent is 15.6%, also below stress levels. Compared with nearby Prospect and Nailsworth, inspect lot size, renovation quality and parking carefully because the compact stock mix can produce large price differences.

For Investors

Investor appeal rests on a 41.8% renting share, a $300 weekly median rent and a 7.6% vacancy rate. The vacancy figure is higher than a tightly constrained rental market would normally suggest, so landlords should allow for leasing competition and test achievable rent by dwelling type. Demand is supported by 798 employed residents, including 503 full-time and 295 part-time workers, while healthcare accounts for 25.6% of industry employment and education 12.1%. Development activity reached 18 applications in 12 months, including a land division from 1 into 2 allotments, indicating some incremental change rather than a large project pipeline. The price point is high relative to the $300 rent, so gross yield should be calculated carefully before purchase. Compared with lower-priced inner-north options, the premium purchase price makes cash flow more sensitive to vacancy and maintenance.

Collinswood's housing market combines premium pricing with a relatively mixed tenure structure. That fall is a notable contrast with a market that may appear stable from its premium address, so buyers should separate suburb-wide movement from the condition and land value of individual sales. Only 25.8% of residents own outright and 29.8% hold a mortgage, while 41.8% rent and 2.6% sit in other tenure categories. Dwellings are split between 46.6% separate houses, 31.0% semi-detached homes and 22.4% apartments. Two-bedroom stock leads at 43.8%, followed by three-bedroom dwellings at 30.1%, while 19.9% have four or more bedrooms. Compared with nearby Prospect and Nailsworth, the semi-detached and apartment shares point to a less uniformly detached market. The $2,077 monthly mortgage figure is 24.9% of household income, below the stated stress level.

Economy & Employment

Collinswood's employment base is tilted towards services and public-facing professions. Healthcare is the largest industry at 25.6% and 162 workers, followed by education at 12.1% and 77, professional and technical services at 10.1% and 64, public administration at 8.5% and 54, and construction at 7.3% and 46. Professionals are the largest occupation group at 290, ahead of managers at 103 and clerical or administrative workers at 102. The labour-force participation rate is 70.0%, with unemployment at 3.7%, while 60.1% of workers are full-time. Household income sits at the 72.1st percentile, higher than the national midpoint, which helps explain the suburb's ability to support premium housing. The 11.1% work-from-home rate is below the 72.4% share driving to work, so transport and access to nearby employment remain important. The mix is more professional than industrial, but construction still provides a material 7.3% base.

Transport to Work

School access in Collinswood is address-sensitive, so families should check the exact enrolment zone and nearby government, Catholic and independent options before buying. The compact 0.52 sq km footprint and 2,856.6 people per sq km can make shops, services and neighbouring facilities easier to reach, but parking and traffic conditions deserve a street-level check. Daily travel is car-led, with 72.4% driving, compared with 7.8% using public transport and 3.9% walking or cycling; 11.1% work from home. Recorded crime is 28.7 incidents per 1,000 residents, a low-crime signal compared with many urban settings, although 43 total incidents means small-area counts can move noticeably. The resident base includes 1,496 people, a median age of 36 and 18.0% volunteering, supporting a socially active profile. Compared with more car-dependent outer suburbs, Collinswood's inner-north position should shorten some trips, but the 7.8% public-transport share shows that many households still rely on cars.

Growth Outlook

Collinswood's near-term growth case should be treated as selective rather than assumed. The suburb recorded 18 development applications over 12 months, including a 1 into 2 land division, a carport extension and a shed, which points to small-lot and property-level change rather than a major supply wave. A forward view should test annual growth, migration direction, gentrification stage and wider-area population change before underwriting a strong uplift. With 41.8% renting, 32.8% born overseas and 55.3% university qualified, demand can remain supported if professional and inner-city households continue to value the location. Compared with nearby Prospect and Nailsworth, Collinswood's 2,856.6 people per sq km makes infill and renovation more relevant than broad outward expansion.

Frequently Asked Questions

Is Collinswood a good suburb to live in?

Collinswood suits residents seeking a premium, compact inner-north suburb with a median age of 36, household income at the 72.1st percentile and recorded crime of 28.7 incidents per 1,000 people. Car use is high at 72.4%, so check parking, traffic and daily transport needs.

What schools are in Collinswood?

School access in Collinswood depends on the exact address and enrolment zone. Check nearby government, Catholic and independent options before buying, because the suburb covers only 0.52 sq km and schools just beyond the boundary may still be practical. Confirm current intake rules and transport arrangements for each property.

Is Collinswood safe?

Collinswood recorded 43 offences, equal to 28.7 incidents per 1,000 residents. That is a low-crime signal compared with many urban areas, but buyers should still inspect street lighting, activity levels and property security. Recent local trends are more useful than relying on one annual count.

How is Collinswood's population changing?

Collinswood has 1,496 residents and appears relatively settled, with 79.4% staying at the same address and turnover of 20.6%. Eighteen development applications in 12 months point to incremental property change. Future population momentum should be checked across the wider area before assuming a particular growth rate.

What languages are spoken in Collinswood?

Collinswood has an overseas-born share of 32.8%, above the national comparison by 11.2 percentage points. Recorded languages include Nepali with 24 speakers, Greek with 21, Punjabi with 20, Mandarin with 14 and Hindi with 14, reflecting a broader cultural mix than ancestry figures alone suggest.

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.
