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 Llandilo is around 1,644. This reflects an increase from the 2021 Census figure of 1,618 people, a rise of 26 individuals (1.6%). The current resident population estimate of 1,636 by AreaSearch, based on the latest ERP data release by the ABS in June 2024 and validated new addresses since the Census date, indicates this growth. This results in a density ratio of 127 persons per square kilometer. Over the past decade, Llandilo has shown resilient growth with a compound annual growth rate of 12.5%, outpacing its SA3 area. Natural growth contributed approximately 43.0% to overall population gains during recent periods, with all drivers including interstate and overseas migration being positive factors.

AreaSearch is using 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 released in 2022 with a base year of 2021 for areas not covered. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. By 2041, the suburb of Llandilo is forecasted to increase its population by 779 persons based on aggregated SA2-level projections, reflecting a total increase of 66.8% over the 17-year period.

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

Based on AreaSearch analysis of ABS building approval numbers allocated from statistical area data, Llandilo has experienced approximately one dwelling receiving development approval per year over the past five financial years up to FY-25. This totals an estimated five homes. So far in FY-26, zero approvals have been recorded. On average, 119.2 people have moved to the area annually for each dwelling built between FY-21 and FY-25, indicating substantial demand outstripping supply.

This has led to heightened buyer competition and pricing pressures. Commercial approvals registered this financial year amount to $163,000, suggesting a predominantly residential focus in Llandilo's development activity. Compared to Greater Sydney, Llandilo shows significantly reduced construction levels, with 89.0% below the regional average per person. This scarcity of new dwellings typically strengthens demand and prices for existing properties. Furthermore, this activity is lower than national averages, reflecting market maturity and potential development constraints. All new construction in Llandilo has comprised attached dwellings since FY-21, marking a significant departure from its existing housing patterns (currently 99.0% houses). This shift suggests diminishing developable land availability and responds to evolving lifestyle preferences and housing affordability needs.

The estimated population count per dwelling approval in Llandilo is 3815 people, reflecting its quiet, low activity development environment. According to AreaSearch's latest quarterly estimate, the area will gain 1,098 residents by 2041. If current construction levels persist, housing supply could lag population growth, likely intensifying buyer competition and underpinning price growth in Llandilo.
