Llandilo

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

As per AreaSearch's analysis of ABS population updates and new addresses validated since the 2021 Census, the suburb of Llandilo had an estimated population of around 1,645 as of May 2026. This figure represents a rise of 27 individuals (1.7%) from the 2021 Census count of 1,618 residents. The increase is inferred from AreaSearch's estimation of the resident population based on the latest ERP data release by the ABS in June 2025 and an additional 8 validated new addresses since the Census date. This results in a population density ratio of 127 persons per square kilometer, indicating significant space per person and potential room for further development. Natural growth was the primary driver of population growth in the suburb, contributing approximately 43.0% of overall population gains during recent periods.

However, all factors including interstate migration and overseas migration were positive contributors. AreaSearch is adopting 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 where applicable, released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for the years 2032 to 2041. According to aggregated SA2-level projections, the suburb is forecasted to experience a significant population increase in the top quartile of statistical areas analysed by AreaSearch. By 2041, the area is expected to have increased by 582 persons, reflecting an overall increase of 35.4% over the 16-year period.

The level of residential development activity in Llandilo is very low in comparison to the average area assessed nationally by AreaSearch

AreaSearch analysis of ABS building approval numbers shows Llandilo has received around 1 dwelling approval per year on average over the past five financial years, totalling approximately five homes. No approvals have been recorded so far in FY26. The population decline in recent years has resulted in adequate development activity relative to population size, which is positive for buyers.

Commercial approvals registered this financial year amount to $163,000, indicating a predominantly residential focus. Compared to Greater Sydney, Llandilo shows significantly reduced construction (90.0% below regional average per person), which typically strengthens demand and prices for existing properties. This activity is also lower than the national average, suggesting market maturity and possible development constraints. All new constructions have been attached dwellings, offering affordable entry pathways and attracting downsizers, investors, and first-time purchasers. This shift marks a significant departure from current housing patterns (99.0% houses), indicating diminishing developable land availability and responding to evolving lifestyle preferences and housing affordability needs. The estimated population per dwelling approval is 3288 people, reflecting the area's quiet, low activity development environment. Population forecasts indicate Llandilo will gain 582 residents by 2041 (AreaSearch quarterly estimate).

If current construction levels persist, housing supply may lag population growth, potentially intensifying buyer competition and supporting price growth.

This contrasts with Greater Sydney, where employment rose by 2.2%. Jobs and Skills Australia's national employment forecasts from May-25 project national employment growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Llandilo's employment mix suggests local employment should increase by 5.6% over five years and 11.7% over ten years, though these are simple weighted extrapolations for illustrative purposes and do not account for localised population projections.
