NSW 2251 Census 2021 + Live DA Data

Kincumber

A median age of 48 (8 years above the national figure) and 55.8% of the labour force not participating reveal Kincumber as a retirement-leaning Central Coast suburb where house prices have softened 3.8% from $1,057,500 to $1,017,500 over the past year. Despite median incomes at just the 33rd percentile, 38.9% own outright, the financial signature of retirees who bought decades ago. Rents grew 50.9% over the prior decade, yet mortgage stress has hit 36.5% of income, well above the 30% threshold, squeezing newer buyers entering at current prices.

The median house price of $1,041,000 has declined 3.8% from its $1,057,500 peak in 2024 to $1,017,500 in 2025. Monthly mortgage payments of $2,085 consume 36.5% of household income, flagging mortgage stress. Stock is 65.6% detached, but 30.0% semi-detached provides a meaningful townhouse alternative. Bedrooms distribute broadly: 37% have 3 bedrooms, 33% have 4+, and 26.3% have 2. With only 44.2% labour force participation and incomes at the 33rd percentile, new buyers on typical local salaries face affordability challenges that existing retirees do not.

For Buyers

The median house price of $1,041,000 has declined 3.8% from its $1,057,500 peak in 2024 to $1,017,500 in 2025. Monthly mortgage payments of $2,085 consume 36.5% of household income, flagging mortgage stress. Stock is 65.6% detached, but 30.0% semi-detached provides a meaningful townhouse alternative. Bedrooms distribute broadly: 37% have 3 bedrooms, 33% have 4+, and 26.3% have 2. With only 44.2% labour force participation and incomes at the 33rd percentile, new buyers on typical local salaries face affordability challenges that existing retirees do not.

For Investors

Weekly rent of $400 against $1,041,000 median implies a gross yield of only 2.0%, among the lowest on the Central Coast. The 21.7% rental share offers a moderate tenant base, and vacancy at 5.5% sits above the balanced benchmark. Rent-to-income at 30.3% already crosses the stress threshold for tenants. With 59 DAs lodged in 12 months (including subdivisions and new dwellings), the supply pipeline is active. The aging-trajectory signal and 0.2% annual population growth suggest demand will not outpace this supply.

Detached houses make up 65.6% of stock, with a substantial 30.0% semi-detached component and 4.3% apartments. Outright owners (38.9%) and mortgage holders (39.4%) nearly match, while renters sit at 21.7%.

Both mortgage stress (36.5%) and rent stress (30.3%) exceed the 30% threshold, unusual for a suburb where nearly 4 in 10 own outright.

Population is forecast to reach 7,728 by 2031, growing at only 0.2% per year (15 persons/year), well below the national growth rate.

Net overseas migration adds just 38 people per year, while net internal migration runs at -25, meaning the suburb is slowly losing residents to other areas. Gentrification score of 49 (active) during the prior decade has stalled, with prices now declining 3.8%.

Frequently Asked Questions

Is Kincumber a good suburb to live in?

Kincumber suits retirees and established homeowners (38.9% own outright) with 3 schools scoring above ICSEA 1,000 and low 3.5% unemployment. However, new buyers face mortgage stress at 36.5% of income, and population growth of 0.2%/year indicates a static community. IRSAD decile 5 places it at the national midpoint.

What is the median house price in Kincumber?

The median house price is $1,041,000, declining 3.8% from $1,057,500 in 2024 to $1,017,500 in 2025. Monthly mortgage repayments of $2,085 are significant against household incomes at the 33rd percentile nationally, pushing mortgage-to-income to 36.5%.

What schools are in Kincumber?

Kincumber has 3 schools: Holy Cross Catholic Primary (ICSEA 1,081, 285 students), Kincumber High School (Government, ICSEA 1,045, 1,002 students), and Kincumber Public School (Government, ICSEA 1,004, 364 students). All exceed the national ICSEA benchmark of 1,000.

Is Kincumber safe?

Suburb-level crime data is not available. SEIFA IRSD decile of 6 indicates moderate relative advantage. The low 3.5% unemployment, 38.9% outright ownership, and 80.4% residential stability suggest a settled community profile typically associated with below-average crime rates.

Is Kincumber good for property investment?

Gross yield of 2.0% ($400/week on $1,041,000) is poor, and prices fell 3.8% in the past year. Vacancy at 5.5% exceeds the 3% benchmark, while 59 DAs in 12 months add supply. Rent stress at 30.3% limits scope for rent increases. Capital and income returns are both under pressure.

How is Kincumber's population changing?

Population is forecast to grow just 0.2% annually (15 people/year) to 7,728 by 2031. The median age of 48 sits 8 years above the national figure, and the senior share grew 4.6pp over the decade. Net internal migration is -25/year, meaning the suburb gradually loses residents to other areas.

How much development is happening in Kincumber?

59 development applications were lodged in the past 12 months, including new dwellings, subdivisions, and commercial signage. For a suburb of 7,398 people, this is substantial activity, roughly 8 DAs per 1,000 residents, above the Central Coast average and likely driven by lot splitting on larger blocks.

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.
