Llandilo
A $2,503,000 median house price in a suburb of just 1,618 people tells you something unusual is happening at Llandilo. Sitting in the outer-western edge of Greater Sydney, this low-density pocket scores IRSD decile 8 and IRSAD decile 8, placing it above average nationally on both disadvantage and advantage indexes. Household income sits at the 70.2nd percentile nationally, and the average household size of 3.4 is 0.9 above the national figure, pointing to large family-oriented properties on generous lots. With 99.3% of dwellings being separate houses and 67.4% having four or more bedrooms, Llandilo is one of the most exclusively detached, large-home suburbs anywhere in NSW.

The median house price of $2,503,000 reflects demand for large residential lots in a suburb where 99.3% of dwellings are separate houses. Four-plus bedroom homes account for 67.4% of the stock, and three-bedroom homes a further 25.3%, meaning small dwellings are almost nonexistent compared to state norms. Price data shows the median held stable at $2,505,000 in 2024 versus $2,503,000 in 2025, a flat 0.1% movement that signals the premium end is consolidating rather than retreating. Monthly mortgage repayments average $2,550, and the mortgage-to-income ratio of 31.3% exceeds the 30% stress threshold, so buyers at this price point are stretching even at a 70th-percentile income. Outright ownership at 49.8% is high, suggesting many properties are held by established owners with no debt.

For Investors
The investment case at Llandilo requires careful reading. Weekly rent of $500 against a $2,503,000 median implies a gross yield below 1.1%, which is well below typical investment benchmarks. The vacancy rate of 4.8% is elevated, suggesting limited rental demand relative to stock, because renters account for only 27.2% of households. Development activity is thin at 9 applications in 12 months, mostly sheds and dual occupancies, which limits near-term supply pressure but also signals a slow-moving market. Population growth at 5.39% annually across the broader SA2 area and net overseas migration averaging 122 per year provide a long-term demand backdrop. The investment case leans heavily on land-value appreciation in a supply-constrained, large-lot suburb rather than rental yield.

Tenure
Llandilo is one of Sydney's most uniformly detached suburbs: 99.3% of dwellings are separate houses, a share that is extremely high compared to metropolitan norms. The stock skews large, with 67.4% of homes having four or more bedrooms. Outright owners at 49.8% outnumber both mortgage holders (23.0%) and renters (27.2%), an ownership structure that reflects long-established residents on freehold lots. The median house price held near $2,503,000 in 2025, essentially flat from $2,505,000 in 2024. Monthly mortgage repayments of $2,550 against household income produce a mortgage-to-income ratio of 31.3%, above the 30% stress threshold. Because the suburb is almost entirely detached houses on large lots, buyers compete for scarce supply in a land-constrained segment.

Economy & Employment
Construction is the dominant industry at 25.3% of employed residents, a share substantially higher than state averages, which fits the suburb's large-lot, owner-builder character.

By occupation, Clerical and Admin workers lead (121), followed by Managers (104) and Machinery and Drivers (93), the last reflecting proximity to logistics and trade corridors. Unemployment is low at 3.4% and full-time employment rate reaches 59.3%.

Transport to Work
Car dependency is high at 88.8% using a car to get to work, above state averages, which is expected for a low-density suburb 12.89 km2 in area with limited public transport infrastructure. Walking and cycling accounts for 3.4% of commuters. Llandilo scores IRSAD decile 8, placing it in the top 30% nationally for combined advantage and disadvantage, while the IER decile of 10 confirms very high economic resources. The housing stress picture is mixed: rent-to-income at 26.6% stays below the 30% stress threshold, but mortgage-to-income at 31.3% exceeds it. No schools are recorded within the suburb boundary in this dataset, so families rely on institutions in neighbouring suburbs. The volunteering rate of 7.1% is modest and 6.9% of residents need daily assistance.

High GrowthPopulation growth across the Llandilo SA2 area runs at 5.39% annually, with the SA2 population rising from 14,805 in 2023 to 15,589 in 2025. Medium forecasts project the SA2 population reaching 20,929 by 2031, adding over 5,000 residents. Migration is balanced, with net internal migration averaging 153 per year and net overseas migration 122 per year. The 10-year population change of 735.7% marks Llandilo as one of the fastest-growing areas in NSW, driven by greenfield land release. The gentrification stage is classified as new development rather than gentrification, which is consistent with the suburb being in early establishment. Real income growth of 67.5% over the decade and rent growth of 51.4% both run above typical national benchmarks.

How to read these comparisons
Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.
Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.
Data sources: ABS 2021 Census (demographics, income, tenure), state Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
