Llandilo

An assessment of population growth drivers in Llandilo reveals an overall ranking slightly below national averages considering recent, and medium term trends

As of Feb 2026, the estimated population of the suburb of Llandilo is around 1,644. This figure reflects a growth of 26 people since the 2021 Census, which reported a population of 1,618. The increase is inferred from AreaSearch's resident population estimate of 1,636 in Jun 2024, along with validation of seven new addresses since the Census date. This results in a population density ratio of 127 persons per square kilometer. Natural growth contributed approximately 43.0% to overall population gains during recent periods, while other factors such as interstate and overseas migration also played positive roles.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022, and NSW State Government's SA2 level projections for areas not covered by this data, released in 2022 with a base year of 2021. Applying growth rates from these aggregations to all areas, forecasts indicate a significant population increase in the top quartile of statistical areas analysed by AreaSearch. By 2041, the suburb of Llandilo is expected to increase its population by 674 persons, reflecting an overall increase of 40.5% over the 17 years.

Residential development activity is lower than average in Llandilo according to AreaSearch's national comparison of local real estate markets

AreaSearch analysis of ABS building approval numbers shows Llandilo has had approximately 1 dwelling receiving development approval per year over the past five financial years, totalling an estimated 5 homes. No approvals have been recorded so far in FY-26. This results in around 118.4 people moving to the area for each dwelling built annually between FY-21 and FY-25, indicating supply is significantly lagging demand. There have been $163,000 in commercial approvals registered this financial year, suggesting a predominantly residential focus.

Compared to Greater Sydney, Llandilo shows substantially reduced construction, with 90.0% below the regional average per person. This scarcity of new dwellings typically strengthens demand and prices for existing properties. The activity is also lower than nationally, reflecting market maturity and possible development constraints. All new construction has been comprised of attached dwellings, marking a significant departure from existing housing patterns which are currently 99.0% houses. This suggests diminishing developable land availability and responds to evolving lifestyle preferences and housing affordability needs. The estimated count of 3824 people in the area per dwelling approval reflects its quiet, low activity development environment. Population forecasts indicate Llandilo will gain 666 residents through to 2041.

Should current construction levels persist, housing supply could lag population growth, likely intensifying buyer competition and underpinning price growth.
