VIC 3023 Census 2021 + Live DA Data

Cairnlea

Vietnamese ancestry at 3,009 residents is the largest single group in Cairnlea, ahead of Chinese (1,244) and Filipino (696), producing a suburb where 53.2% were born overseas, 31.6 percentage points above the national baseline. Despite this, household income sits at the 77.2 percentile nationally, well above the median, yet SEIFA places Cairnlea at IRSAD decile 4, creating an unusual disconnect between earnings and overall advantage. The explanation lies in the IRSD decile 3 reading, indicating pockets of relative disadvantage beneath the income surface. Prices have grown at 5.6% CAGR over 14 years, reaching $1,027,500 in mid-2024, a 114.1% gain from $480,000 in 2013. The suburb experienced a COVID population dip of 3.0% from which it has not fully recovered, one of the few Melbourne suburbs in that position.

The $1,027,500 median sits 5.7% below a peak of $1,090,000 in early 2024, representing a price correction that may offer entry opportunities. Detached houses at 88.6% dominate, and 64.6% of dwellings have four or more bedrooms, the second highest proportion in this batch, reflecting a housing fabric built for large households. Average household size of 3.4 is 0.9 above the national figure, consistent with multi-generational family living. The median monthly mortgage of $1,883 produces a mortgage-to-income ratio of just 21.1%, remarkably low given the $1,027,500 median, and well below the 30% stress threshold. This ratio suggests many current mortgage holders purchased at lower price points. Vacancy at 3.6% is tight, meaning resale demand is healthy. The suburb has minimal public transport access at 3.5% usage.

For Buyers

The $1,027,500 median sits 5.7% below a peak of $1,090,000 in early 2024, representing a price correction that may offer entry opportunities. Detached houses at 88.6% dominate, and 64.6% of dwellings have four or more bedrooms, the second highest proportion in this batch, reflecting a housing fabric built for large households. Average household size of 3.4 is 0.9 above the national figure, consistent with multi-generational family living. The median monthly mortgage of $1,883 produces a mortgage-to-income ratio of just 21.1%, remarkably low given the $1,027,500 median, and well below the 30% stress threshold. This ratio suggests many current mortgage holders purchased at lower price points. Vacancy at 3.6% is tight, meaning resale demand is healthy. The suburb has minimal public transport access at 3.5% usage.

For Investors

Renters account for only 15.4% of households, well below the national average, reflecting the strong owner-occupier preference in this family-oriented suburb. Median weekly rent of $400 against the $1,027,500 median would deliver a gross yield of approximately 2.0%, below Melbourne averages. The 3.6% vacancy rate is the tightest in this batch, suggesting strong tenant demand despite the low renter share. Zero development applications were lodged in 12 months, meaning no new supply pipeline. The COVID population dip from 10,452 pre-COVID to a low of 10,142, with only partial recovery to 10,035 by 2025, creates uncertainty about future growth. Net internal migration is sharply negative at 216 per year, offset partly by overseas inflows of 129 per year.

Demographics

Vietnamese (3,009), Chinese (1,244) and Filipino (696) ancestries dominate, with English at just 644 residents, making this one of Melbourne's most Asian-influenced suburbs. The 53.2% overseas-born rate is 31.6 percentage points above national. Cantonese (208 speakers), Macedonian (125), Punjabi (89), Arabic (84) and Urdu (80) lead the non-English languages, but Vietnamese itself is likely the largest language group given the 3,009 ancestry count. Buddhism (1,953) is the second largest religion behind Christianity (4,024), with Islam at 983, reflecting the Asian and Middle Eastern heritage mix. Average household size of 3.4 sits 0.9 above the national figure, and 14.3% of families are couples without children, the lowest share in this batch, confirming multi-generational family structures.

Mortgage holders at 50.8% form the majority, well above outright owners at 33.8% and renters at 15.4%, a profile where over half the suburb is carrying debt. The price record shows strong appreciation: from $480,000 in 2013 to a peak of $1,090,000 in early 2024, a 114.1% gain. The latest median of $1,027,500 represents a 5.7% pullback from that peak. Four-plus bedroom homes at 64.6% and three-bedroom at 30.5% account for 95.1% of stock, leaving almost no small-format options. The 21.1% mortgage-to-income ratio is among the lowest in this batch, indicating existing mortgage holders are well-positioned despite rate rises. SEIFA IER decile 8 confirms strong economic resources, while IEO decile 5 places education and occupation at the national midpoint, a reversal of the typical migrant-suburb pattern where education leads income.

Economy & Employment

Healthcare leads at 16.9% (462 workers), followed by Retail at 8.9%, Construction at 8.4%, Education at 8.4% and Transport at 8.3%. The employment distribution is more dispersed than typical, with no single industry exceeding 17%. Professionals (853) lead occupations, but Clerical/Admin (693), Labourers (583) and Machinery/Drivers (581) collectively form a large blue-collar contingent. The 7.1% unemployment rate exceeds the national average, and real income has declined 3.6% over the decade, meaning wages have fallen behind inflation. SEIFA IER decile 8 vs IEO decile 5 reveals an unusual pattern: economic resources are strong but education and occupation indicators sit at the national midpoint, suggesting wealth has been built through property and multi-income households rather than professional advancement.

Population Forecast

+1.72%/yr

(+173 people/yr)

Established

The trend rate of 1.72% per year projects 173 additional persons annually, but the reality has been more turbulent. Cairnlea experienced a COVID dip of 3.0% from a pre-COVID population of 10,452, falling to 10,142, and by 2025 has only recovered to 10,035, still 1.3% below the pre-pandemic level. Medium projections suggest recovery to 11,820 by 2031, but this assumes overseas migration at 129 per year continues. Net internal migration is strongly negative at 216 per year, indicating that residents who can move domestically are choosing to leave. The ageing trajectory shows senior share rising 6.4 percentage points and young share falling 5.4 points over the decade. Gentrification score of 0 confirms no signs of demographic upgrading.

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.
