Carss Park
At a median house price of $2,159,000 on just 0.63 square kilometres, Carss Park packs serious wealth into a small footprint. Household income sits at the 87.9th percentile nationally, yet the suburb holds only 1,265 residents, making it one of the most thinly populated premium addresses on the southern shores of Sydney. The median age of 46 is 6 years above the national figure, and 41.9% of dwellings are owned outright, a pattern that reflects long-term residents holding onto high-value assets rather than cycling through the market. With 86% of residents staying put year to year and 81% living in separate houses, the suburb signals stability and low supply turnover.

2024-2025 (PSI derived)
The median house price was $1,850,000 in 2024 and rose to $2,450,000 in 2025, a 32.4% jump that outpaces most comparable Sydney markets over the same period. The current PSI-derived median sits at $2,159,000. Stock composition strongly favours detached homes, which make up 81% of dwellings, well above the state average for suburban areas. Over half of all dwellings (50.3%) have 4 or more bedrooms, suited to families rather than downsizers. Monthly mortgage repayments average $3,000, but the mortgage-to-income ratio reaches 30.2%, above the standard stress threshold, meaning buyers at the median are stretching even with household incomes in the top 12% nationally. Outright ownership at 41.9% exceeds mortgage holders at 39.4%, pointing to an established owner base rather than recent entrants.

For Investors
The rental market here is thin: only 18.8% of dwellings are rented, well below the national average, and weekly rent sits at $288, low relative to the $2,159,000 median, implying a gross yield under 1%. The vacancy rate of 5.1% suggests modest demand for rentals, consistent with a suburb where most residents own their home. Development activity is modest at 13 applications in 12 months, including dual occupancy and subdivision CDCs, which signals some incremental supply growth but not a pipeline that will dilute existing stock quickly. The 32.4% price increase from 2024 to 2025 is the primary investment case, though one-year price spikes can revert. The 14% annual turnover rate means fewer than 1 in 7 properties change hands each year, limiting transaction opportunities.

Tenure
Separate houses dominate at 81%, with semi-detached at 17.2% and apartments a minimal 1.8%, making this an almost exclusively low-density residential area. Four-plus bedroom dwellings account for 50.3% of stock, compared to three-bedroom homes at 31%, signalling family-sized accommodation rather than entry-level housing. Prices moved from $1,850,000 in 2024 to $2,450,000 in 2025, a 32.4% increase over one year. Tenure divides into 41.9% owned outright, 39.4% with a mortgage and 18.8% renting. The mortgage-to-income ratio of 30.2% exceeds the 30% stress threshold despite household income at the 87.9th percentile, a signal of how high purchase prices are relative even to above-average earnings. Renters face below-market rents of $288 per week against the backdrop of limited rental supply.

Economy & Employment
The local workforce skews toward high-income professional sectors. Professional/Tech leads at 18.3% of employed residents (75 workers), ahead of Healthcare at 13.2% (54) and Construction at 9.8% (40), which is notably elevated compared to inner-city Sydney. Education (9.5%) and Finance (8.5%) round out the top five. By occupation, Professionals (181) and Managers (126) are the two largest groups, consistent with a suburb where 53% hold university qualifications, 22.9 points above national. The unemployment rate is 3.4% and full-time employment accounts for 62.6% of jobs. The participation rate of 48.1% is lower than expected for household incomes at the 87.9th percentile, which reflects the older median age of 46 pulling more residents out of the labour force.

Car dependence is high in Carss Park: 87.4% of residents drive to work, well above the national average, and only 4.3% use public transport, consistent with a suburb not well connected to rapid rail.

Only 6.2% of residents (76 people) require daily assistance, low for a suburb with a median age of 46, and the volunteering rate of 13.7% reflects moderate community participation.

Frequently Asked Questions
Is Carss Park a good suburb to live in?
Carss Park appeals to established families and long-term owner-occupiers. Household income sits at the 87.9th percentile nationally, 81% of dwellings are separate houses, and 86% of residents stay year to year.

Is Carss Park good for property investment?
The price growth case is strong: a 32.4% increase from $1,850,000 in 2024 to $2,450,000 in 2025. However, weekly rent of $288 against a $2,159,000 median implies a gross yield below 1%, and the vacancy rate of 5.1% reflects limited rental demand. Only 18.8% of dwellings are rented, so investors compete for a thin tenant pool.
How is Carss Park's population changing?
Carss Park has a small population of 1,265 residents within a 0.63 square kilometre area. The residential retention rate is high at 86%, meaning only 14% of residents move each year. No population forecast data is available for this suburb, but the modest 13 development applications in 12 months suggest slow, incremental growth.
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.
