NSW 2526 Census 2021 + Live DA Data

Unanderra

An $878,000 median house price paired with household income in just the 25.9th percentile nationally is what defines Unanderra, and the gap drives its housing stress. The Wollongong suburb skews detached, with 78.3% separate houses against only 11.9% apartments, and leans Anglo, led by English ancestry (1,861). University qualifications reach 22.0%, which is 8.1 points below the national figure, while the median age of 42 sits 2.0 years above national. The mortgage-to-income ratio of 37.2% sits well above the 30% stress line, the direct result of premium prices meeting below-median local earnings.

Buyers face an $878,000 median house price against household income in the 25.9th percentile, a mismatch that pushes the mortgage-to-income ratio to 37.2%, above the 30% stress threshold. Prices barely moved over the period, rising 1.6% from $865,000 in 2024 to $879,000 in 2025, so this is a stable rather than fast-appreciating market. The stock favours families: 78.3% are separate houses and three-bedroom dwellings dominate at 51.8%, with four-plus bedrooms at 20.0% and apartments only 11.9%. Average monthly mortgage repayments run about $1,950. Owners are split, with 29.1% holding outright and 26.5% carrying a mortgage, so just over half the suburb is owner-occupied, below the renter share of 44.4%.

For Investors

Renters make up 44.4% of households, a deep tenant pool well above the owner-occupier base, and weekly rent of $285 against the $878,000 median implies a gross yield near 1.7%, low by regional standards. The 4.7% vacancy rate is soft, pointing to adequate supply rather than scarcity. Demand support comes from overseas migration, the primary driver adding a net 63 residents a year, while internal migration removes 14. Rent has grown strongly, up 61.4% over the period, which is the main reason the investment case rests on rental escalation rather than yield or capital growth. Development is modest at 46 applications in 12 months, including secondary dwellings and light industrial change-of-use, so new housing supply is limited and unlikely to dilute rents.

Demographics

The median age of 42 is 2.0 years above the national figure, and the trajectory is aging: the senior share rose 5.1 points while the young share fell 2.8 points over the decade. Overseas-born residents reach 22.0%, marginally above national by 0.4 points, so this is a predominantly Australian-born suburb. Ancestry leans Anglo, led by English (1,861), Scottish (478) and Irish (477), and the top non-English languages are Arabic (52), Italian (40) and Croatian (36), reflecting a longstanding southern European and Balkan presence. University qualifications at 22.0% run 8.1 points below national, consistent with a working trades base. Average household size is 2.4, just 0.1 below national, and couples with children (1,303) outnumber couples without children (1,084).

Tenure tilts toward renting: 44.4% rent, 29.1% own outright and 26.5% carry a mortgage, so renters outnumber either owner group. The stock is overwhelmingly detached at 78.3% separate houses, with apartments at only 11.9% and semi-detached at 9.5%, a family-oriented profile reinforced by three-bedroom homes making up 51.8% of dwellings. The median house price rose just 1.6% from $865,000 to $879,000 across 2024-2025, flat in real terms. The strain shows in repayments: mortgage-to-income at 37.2% is well above the 30% stress threshold, while rent-to-income at 23.5% stays manageable, a divergence that reflects how steep purchase prices are relative to below-median local incomes in the 25.9th percentile.

Economy & Employment

The workforce is anchored in essential services rather than knowledge sectors: Healthcare leads at 24.8% (325 workers), Education follows at 11.0% (144) and Construction at 10.6% (138), with Professional/Tech at 6.9% and Public Admin at 6.4%. By occupation, Professionals (374) lead but Community/Personal (278), Clerical (241) and Labourers (239) together outweigh them, a blue-collar and care-sector mix. This aligns with SEIFA scores clustered mid-range: IRSAD decile 6, IRSD decile 5, IEO decile 6 and IER decile 7, all near the national midpoint. Unemployment reads 7.3%, above the national rate, and participation is low at 41.0% because 2,155 residents are not in the labour force, consistent with the aging profile. Real incomes still grew 19.1% over the decade.

Transport to Work

Unanderra is a car-dependent suburb: 87.1% of commuters drive, while just 2.7% take public transport and 2.7% walk or cycle, both well below what denser suburbs record. No schools are recorded inside the 6.5 km2 boundary in this dataset, so families rely on institutions in neighbouring Wollongong suburbs. On disadvantage, the suburb scores IRSD decile 5, near the national midpoint, and IRSAD decile 6, so most residents sit in the middle band rather than at either extreme. Volunteering runs at 10.4% and 14.2% of residents (737 people) need daily assistance, a higher share that fits the older median age of 42 and the 5.1-point rise in the senior cohort over the decade.

Population Forecast

(-50 people/yr)

Established

Unanderra is contracting slightly: the population is falling at 0.32% a year, roughly 50 people, and the 10-year change is essentially flat at -0.3%, marking it as an established, slow-growth area. Medium forecasts continue the downward trend rather than expansion. The only positive driver is overseas migration, adding a net 63 residents a year, offset by net internal outflow of 14. Despite the static headcount, the gentrification stage reads active with a shift score of 47, signalling change beneath the surface: rent rose 61.4% and real incomes climbed 19.1% over the decade, even as affordability worsened from 42.2% in 2011 to 46.5% in 2021. The suburb recovered fully from a 2.6% COVID dip.

It is detached and family-oriented, with 78.3% separate houses and a median age of 42. The main trade-off is affordability: the $878,000 median meets household income in only the 25.9th percentile.

What schools are in Unanderra?

No schools are recorded inside the 6.5 km2 Unanderra boundary in this dataset, so families rely on schools in neighbouring Wollongong suburbs. The local profile is family-oriented, with three-bedroom homes at 51.8% of dwellings and couples with children numbering 1,303.

Is Unanderra safe?

Detailed crime statistics are not available for Unanderra in this dataset. As an indirect indicator, the suburb scores IRSD decile 5 on relative disadvantage, near the national midpoint, and 14.2% of its residents need daily assistance, a profile consistent with a settled, mid-band area.

Is Unanderra good for property investment?

Rent of $285 a week against an $878,000 median gives a gross yield near 1.7%, low for the region, and the 4.7% vacancy rate is soft. Renters make up 44.4% of households, a deep pool, and rent grew 61.4% over the period, so returns lean on rental escalation more than yield.

How is Unanderra's population changing?

The population is declining at about 0.32% a year, roughly 50 people, and the 10-year change is essentially flat at -0.3%. Overseas migration adds a net 63 residents annually, partly offsetting an internal outflow of 14, while the senior share rose 5.1 points over the decade.

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.
