Sales Detail
Thirlmere has an estimated 5,650 residents, up from 4,986 at the 2021 Census — a change of 664 people, or 13.3%. Growth has averaged 2.1% a year over five years, faster than 81% of areas nationally. 275 new addresses have been validated here since Census night. Interstate and internal migration accounts for 65.0% of that increase. That puts 172 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
According to research on ABS population data updates covering the surrounding region and recent residential locations validated by AreaSearch since the Census, the population of the suburb of Thirlmere is calculated to be approximately 5,650 as of May 2026. This represents an addition of 664 people (13.3%) since the Census in 2021, when the recorded population stood at 4,986 people. This shift is derived from a resident headcount of 5,355, estimated by AreaSearch using the most recent ABS ERP figures from June 2025 alongside a further 275 validated new addresses since the Census.
Such a population count corresponds to a density of 172 persons per square kilometer, which offers considerable room for each inhabitant and potential capacity for subsequent housing expansion. The 13.3% rate of growth in the suburb of Thirlmere since the 2021 census was higher than the state average of 7.1% and the Greater Sydney region, indicating its status as a leading growth area. This expansion was driven mostly by arrivals from other states, which accounted for roughly 65.0% of the total demographic increase, though natural increase and overseas migration also registered positive results. Projections published in 2024 using 2022 as a starting point by the ABS and Geoscience Australia for every SA2 region are being utilized by AreaSearch. In instances where an SA2 area is omitted, AreaSearch relies on the NSW State Government's projections released in 2022 with a 2021 baseline. Age category growth trends from these datasets are applied to all locations for the period from 2032 to 2041. Looking forward, the suburb of Thirlmere is expected to experience population expansion that sits above the median for national statistical zones, with an anticipated increase of 987 individuals by 2041 based on these combined SA2 projections, representing an overall expansion of 12.2% across the 16 years.
Frequently Asked Questions - Population
479 new dwellings have been approved in Thirlmere over the past five years, an average of 95 a year. That places the area in the 79th percentile for residential development activity nationally, about 17 approvals per 1,000 residents a year. Of the 103 dwellings approved in the latest reporting year, 68% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 63, well below that longer-run average. Figures come from ABS building approvals aggregated to this Suburb (SAL) boundary and are updated monthly as the ABS releases them.
Detail
Evaluations of ABS building consent statistics compiled by AreaSearch for the local area show that the suburb of Thirlmere averages roughly 95 residential approvals annually, amounting to approximately 479 homes during the last 5 financial years. Thus far in FY-26, 58 consents have been registered. Given that an average of 1.1 people relocated to the suburb of Thirlmere per completed dwelling over the last 5 financial years (from FY-21 to FY-25), the balance between housing demand and supply is stable, supporting steady market conditions, with new homes showing an average construction value of $335,000.
Furthermore, commercial building approvals worth $4.7 million have been registered during this financial year, which highlights the suburb's residential focus. In comparison to Greater Sydney, building activity in the suburb of Thirlmere is slightly more elevated (sitting 23.0% higher than the regional average per capita over the 5 year period), which helps maintain choices for buyers while supporting local real estate demand, even though construction has slowed down of late. This rate is far higher than the national benchmark, showing robust developer interest. Recent building consents consist of 68.0% standalone houses and 32.0% townhouses or semi-detached units, displaying a growing proportion of attached properties that provide options at different price levels, ranging from larger family residences to compact layouts. This indicates a clear departure from current housing stock (which is 90.0% houses), reflecting a reduction in vacant land suitable for development, shifting lifestyle patterns, and the demand for more varied, budget-friendly properties. The ratio of residents to each building approval is roughly 70, showing a growing market. Demographic projections indicate the suburb of Thirlmere is set to add 692 residents by 2041, based on the latest quarterly calculations by AreaSearch. If current building rates persist, the supply of new dwellings should easily satisfy this demand, offering favorable conditions for purchasers and potentially accommodating growth beyond current forecasts.

2,820 residents of Thirlmere are employed, from a labour force of 2,924. Unemployment sits at 3.6%, with participation at 68.3%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.1% nationally over five years. That reflects industry composition only and makes no allowance for local population growth, so in an area growing as fast as this one it understates the likely rise in local jobs. The working-day population is estimated at 4,869, about 86% of the resident population, so more people leave the area for work than travel in. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.
Detail
The suburb of Thirlmere contains a diverse workforce consisting of both white-collar and blue-collar workers, with construction workers particularly well represented. The unemployment rate is only 3.6%, and the local job market grew by 3.2% over the last year, according to AreaSearch data compiled for the area. As of March 2026, 2,820 residents are employed. This unemployment level is 0.6% below the 4.1% rate recorded across Greater Sydney, while workforce participation is very close to the Greater Sydney average of 69.1%. Census records indicate that 25.8% of workers performed their duties from home, though this figure may have been influenced by pandemic containment measures.
The primary employment sectors for local citizens are construction, health care & social assistance, and retail trade. Construction shows a particularly heavy concentration, with local jobs in this field appearing at 2.0 times the regional average. On the other hand, professional & technical roles are scarce, accounting for just 3.8% of the workforce compared to 11.5% across the wider region. There appears to be a shortage of local jobs, as seen by comparing the number of employed residents to those working within the area during the Census. Based on AreaSearch calculations of SALM and ABS statistics for the broader area, the 12-month period recorded a 3.2% rise in employment alongside a 3.8% increase in the labor force, which pushed the unemployment rate up by 0.6 percentage points. In contrast, Greater Sydney saw employment rise by 1.9%, the labor force grow by 1.9%, and unemployment drop slightly. National employment projections from May-25 by Jobs and Skills Australia help clarify potential future trends in the suburb of Thirlmere. These five and ten-year forecasts have been applied to the local workforce structure to model future growth. Nationally, employment is predicted to grow by 6.6% over five years and 13.7% over ten years, though these rates vary significantly by sector. Applying these industry trends to the suburb of Thirlmere suggests employment among residents should grow by 6.1% over five years and 12.8% over ten years, assuming a basic weighted model that does not incorporate local population forecasts.

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 — 275 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (4,986 at the 2021 Census → 5,650 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 (SAL13863). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.
