DemographicsPopulation Growth in Lake Illawarra

Table Chart PROFILE FAQ

Lake Illawarra has an estimated 3,412 residents, up from 3,288 at the 2021 Census — a change of 124 people, or 3.8%. Growth has averaged 0.5% a year over five years. That puts 2,043 residents on each square kilometre. Population is estimated from ABS Estimated Resident Population releases and GNAF address data, re-based from the 2021 Census and updated annually.

Detail

Lake Illawarra's population is calculated to be approximately 3,412 as of May 2026, a figure determined by examining geographic demographic updates from the ABS alongside recent addresses verified by AreaSearch since the Census. Since the 2021 Census recorded 3,288 residents, this represents an addition of 124 individuals (3.8%). This variation is derived from an Estimated Resident Population of 3,408 calculated by AreaSearch using the June 2025 ABS ERP data release, combined with an additional 75 validated new addresses identified after the Census date. With this population level, the density stands at 2,043 persons per square kilometer, exceeding the typical ratio for national locations monitored by AreaSearch.

The suburb's post-Census growth of 3.8% trails the Rest of NSW (4.9%) by 1.1 percentage points, indicating competitive local growth drivers. Demographic expansion in recent times was mostly supported by overseas migration, which accounted for roughly 56.99999999999999% of the overall population rise. Projections developed by the ABS and Geoscience Australia, issued in 2024 with a 2022 baseline, are utilized for each SA2 region. In instances where SA2 regions lack this data, projections from the NSW State Government's 2022 release with a 2021 baseline are applied instead. Age cohort growth rates from these compilations are also projected forward for the years 2032 to 2041. Based on these demographic methods, the total number of residents is projected to decrease over this period, shrinking by 21 persons by 2041. Conversely, expansion is expected within particular age groups, most notably the 25 to 34 cohort, which is projected to grow by 83 people. See the age section for more details.

Approvals are currently running at an annualised 28, broadly in line with that longer-run average.

Detail

According to building approval figures from the ABS allocated to local statistical boundaries, the suburb of Lake Illawarra averaged approximately 23 new residential approvals per year, summing to an estimated 118 homes approved during the past 5 financial years (between FY-21 and FY-25) and 26 during FY-26 so far. With an average of only 0.7 new residents arriving per new home over the past 5 financial years (between FY-21 and FY-25), construction volume is meeting or outpacing demand, offering buyers more options while paving the way for potential population growth beyond current projections, with new builds averaging $386,000 in value.

Furthermore, commercial approvals totaling $835,000 were logged this financial year, which highlights a mainly residential focus. In comparison to the Rest of NSW, the rate of new home approvals per resident in Lake Illawarra is approximately three-quarters, placing it in the 88th percentile of all national areas evaluated, even though building activity has recently accelerated. Approved development consists of 25.0% detached houses and 75.0% attached dwellings. This shift toward higher-density options offers more affordable entry points and suits downsizers, investors, and first-time buyers. This represents a major change from the current housing stock (where houses make up 50.0%), pointing to a decrease in available development land and reflecting shifting lifestyle choices and housing costs. Averaging roughly 92 people per residential approval, Lake Illawarra displays typical low-density traits. As the population is projected to stabilize or decrease, housing demand in Lake Illawarra should ease, potentially opening up opportunities for home buyers.

How the numbers are built

Population

The Census provides the small-area baseline, aggregated from mesh blocks to this boundary. It is then re-based to the ABS Estimated Resident Population (June 2025 release), and new dwellings built since Census night are counted from address data — 75 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (3,288 at the 2021 Census → 3,412 now). Annual growth rates are compound (CAGR), not simple averages.

Age profile

Cohort shares are not raw Census counts. Every cohort is held as a pair — the Census baseline and a current estimate — and the split is re-based using ERP and state population projections, current to May 2026. Median age is the Census median plus modelled change since. Charts that show both are labelled "2021 Census vs Current Estimate".

Property sales

Sourced from the state valuation authority's sales register — current, not Census, and refreshed weekly. Medians are calculated from settled transactions in the period shown; periods with very low transaction counts are flagged or suppressed, because a handful of sales can move a median substantially.

Rents

Derived from state rental bond lodgement data, by dwelling type and bedroom count. Bonds are lodged at the start of a new tenancy, so this reflects new lettings, not the whole rented stock.

Development & infrastructure

Building approvals come from current ABS releases; development applications are collected from council and state planning portals; the infrastructure pipeline is compiled from Infrastructure Australia and local government sources. Applications are matched to this boundary by address or coordinates, so very recent lodgements may not yet appear.

Employment & income

Industry and occupation structure comes from the Census, but the headline labour-market indicators do not. Unemployment and labour force are derived from ABS Small Area Labour Markets (quarterly). The employment outlook applies Department of Employment forecasts for all 19 industry divisions to this area's own industry mix (the agency is now Jobs and Skills Australia), as does the Internet Vacancy Index used for job demand. Because it is weighted on industry composition alone, that outlook carries no allowance for local population growth — in fast-growing areas the real rise in local jobs will typically be higher. Income combines Census household income with ATO taxable-income statistics for FY 2023, indexed forward using the Wage Price Index.

Education, transport & amenities

School enrolments, ICSEA and performance come from ACARA's current release, not the Census. Public transport stops and service frequency are derived from GTFS timetable feeds published by state transport departments. Services and amenities are proximity and count scores built from provider directories, refreshed on their own cycle. The Census contributes only the travel-to-work and qualification measures.

Rankings and benchmarks. Where we rank this area, the comparison set is every area of the same boundary type — suburbs against suburbs, SA2s against SA2s. Benchmarks compare this area against its greater capital city region and the national figure for the same measure and period.

Limits worth knowing. Small areas carry larger error margins, and the ABS introduces small random adjustments to Census counts to protect confidentiality — so totals may not sum exactly. Estimates re-based from regional data describe the area's expected trajectory, not a direct count of it. Figures are indicative for research and are not financial, planning or valuation advice.

Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (SAL12259). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.

Common questions about this page

How do Lake Illawarra suburb boundaries differ from Statistical Areas?
This page uses Suburbs and Localities (SAL) boundaries (suburb-style geography). SAL represents commonly-known suburb names used in addresses, while Statistical Areas (SA2) are designed for census/statistical reporting. Even when sharing the same name, SAL and SA2 boundaries often cover different geographic areas with different populations.
Where does the data on this Lake Illawarra page come from?
AreaSearch compiles this page from official and industry sources — including ABS, Geoscience Australia, Valuer General, Provider directories, DEWR, JSA, State Transport Departments and ACARA — then aggregates them to the boundary shown and calculates the rankings, growth rates and benchmarks itself. Property sales come from the state valuation authority, rents from state rental bond lodgements, development applications from council and state planning portals, school data from ACARA, and public transport from state transport departments.
Is the Lake Illawarra data on this page just from the 2021 Census?
No. Most of this page is maintained well beyond the Census. Sourced entirely from current releases: development & approvals (Jun 2026), property sales & rents (Aug 2026), infrastructure projects (May 2026) and services & amenities (Jul 2026). Built on a Census baseline but carrying newer measures on top: population (to May 2026), age profile (to May 2026), employment (to Mar 2026), income (to FY 2023), education (to Aug 2026), transport (to Jul 2026) and health (to 2024). Population and age cohorts in particular are re-based to the latest ABS Estimated Resident Population rather than left at 2021 counts. Only housing, households and cultural diversity remain wholly Census-based, because no more current small-area dataset exists for those measures.
