Colyton
Machinery and transport drivers are the single largest occupational group in Colyton (603 people), ahead of professionals (396), a reversal of the typical Sydney pattern. Yet house prices climbed to a $940,000 median, driven by Sydney's westward price pressure rather than local income growth (household income sits in just the 49th percentile). The SEIFA IRSAD decile of 2 and university attainment of 19.6% (10.5 points below national) confirm a working-class suburb where 95.1% detached housing provides family-sized homes at below-Sydney-average pricing.

At $940,000, Colyton sits below Sydney's metro median but prices rose 8.8% from $910,000 in 2024 to $990,000 in 2025. Three-bedroom homes dominate at 58.8%, with 29.5% having 4+ bedrooms.

Bennett Road Public School (ICSEA 912, 646 students) is the only local school, scoring 88 points below the national benchmark. With 72 development applications in 12 months, including secondary dwellings, densification is active.

For Investors
A 4.1% vacancy rate is near equilibrium, and 33.9% of residents rent, providing a solid tenant pool. Weekly rent at $380 against a $940,000 median gives a gross yield of around 2.1%, low even by Sydney standards. Population growth of 1.2% annually (167 people/year) is modest, driven by overseas migration (+134/year) offsetting internal outflow (-93/year). The 72 development applications in 12 months, dominated by secondary dwellings and semi-detached constructions, signal dual-occupancy subdivision activity. Rent grew 30% over the decade.

Frequently Asked Questions
Is Colyton a good suburb to live in?
Colyton sits in the 2nd SEIFA IRSAD decile (bottom 20%) with limited public transport (2.4% usage) and one local school scoring below the national average (ICSEA 912). However, the $940,000 median is below Sydney's metro figure, mortgage stress at 29.3% stays under the threshold, and the 82.8% stability rate signals a settled community.
What is the median house price in Colyton?
The median is $940,000 (PSI derived for 2024-2025), up 8.8% from $910,000 in 2024 to $990,000 in 2025. Mortgage stress at 29.3% of household income is close to the 30% threshold, because household income sits in just the 49th percentile nationally.
What schools are in Colyton?
Bennett Road Public School (Government primary, ICSEA 912, 646 students) is the only school within the suburb. It scores 88 points below the national ICSEA average of 1000. Families seeking secondary education or higher-performing primaries need to look in adjacent suburbs.
Is Colyton safe?
No suburb-level crime data is available. The SEIFA IRSD decile of 2 (bottom 20% for disadvantage) and 7.2% unemployment are factors typically associated with above-average crime. The 82.8% residential stability and 66.1% home ownership rate (outright plus mortgage) are mitigating indicators.
Is Colyton good for property investment?
The 4.1% vacancy rate is near equilibrium, and 33.9% of residents rent. However, the 2.1% gross yield ($380 rent vs $940,000 median) is low for Sydney. The 72 development applications in 12 months, including secondary dwellings, indicate active subdivision that could add rental supply.
How is Colyton's population changing?
Population grows at 1.2% annually (167 people/year), driven by overseas migration (+134/year). Growth is classified as 'all ages' with early gentrification signs (score 23), accelerating from 5% to 17%. Real income grew 14.2% over the decade, and 72 development applications signal active densification.
What recent development is happening in Colyton?
There were 72 development applications in 12 months, dominated by secondary dwellings and semi-detached constructions. This dual-occupancy subdivision activity is converting single-lot detached homes into higher-density configurations, consistent with broader western Sydney infill trends.
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.
