Lilli Pilli
Household income in the 99.2nd percentile nationally sets the tone for Lilli Pilli, a compact 0.61 km2 suburb in Sydney's southern reaches where median house prices sit at $2,080,000. What makes the profile stand out is the ownership structure: 51.1% of residents own their home outright, meaning the majority carry no mortgage at all, a ratio far above typical Australian suburbs. University qualifications reach 47.6%, some 17.5 percentage points above the national average, and the median age of 44 is 4 years older than the national figure, pointing to an established, high-income, owner-occupier community with very low transience.

At $2,080,000, the median house price places Lilli Pilli well above Sydney's broader median. The price moved from $1,670,000 in 2024 to $2,315,000 in 2025, a 38.6% rise in a single year, though this figure reflects a small market and should be read with care. Separate houses dominate at 94.8% of dwellings, with 72.7% having four or more bedrooms, reflecting large family homes rather than apartment stock. Monthly mortgage repayments average $4,000, and the mortgage-to-income ratio sits at 25.5%, below the 30% stress threshold despite the high entry price. Only 4.7% of residents rent, which means buyers are rarely competing with investor-driven churn.

For Investors
The investment case for Lilli Pilli is constrained by thin rental demand. Just 4.7% of dwellings are rented, compared to the national renter share of around 30%, and weekly rent averages $900. Against a $2,080,000 median, that implies a gross yield near 2.3%, which is low relative to the capital required. The vacancy rate of 2.7% is moderate. Development activity recorded 27 applications over 12 months, including secondary dwellings and alterations, suggesting the suburb is slowly adding supply at the margins. With 82.5% of residents remaining at the same address over five years, turnover is extremely low, meaning opportunities to purchase arise infrequently.

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.
