2024-2025 (PSI derived)
The median house price is $835,000 based on the 2024-2025 PSI-derived data, with prices moving from $820,000 in 2024 to $852,500 in 2025, a 4.0% gain over one year. Monthly mortgage repayments average $1,800, and the mortgage-to-income ratio of 27.8% sits below the 30% stress threshold, so buyers are not stretched by national standards. Stock is almost entirely separate houses at 96.7%, with 4-plus bedroom homes making up 44.5% of dwellings and 3-bedroom at 40.1%, reflecting a family-oriented layout. Outright owners account for 36.7% compared to 43.5% on mortgages, suggesting a mix of long-standing residents and more recent buyers who have not yet paid down debt.

For Investors
Renters make up 19.8% of the market, lower than the national average, and weekly rent sits at $385. The 10.9% vacancy rate is notably elevated, signalling that rental demand does not fully absorb available stock, which creates downside risk for landlords. Net internal migration averages 98 arrivals per year, the primary driver of population growth at 1.47% annually, which is above the NSW average and provides a steady tenant pipeline. Development activity recorded 25 applications in the past 12 months, mostly alterations and pool additions rather than new dwelling supply. Rent grew 46.3% over the decade, well above typical income growth, which supports the long-term case for holding rental property here despite the current vacancy pressure.

Demographics
The median age of 42 is 2.0 years above the national figure, and the aging trajectory is clear: the senior share rose 3.3 points while the working-age share fell 1.1 points over the decade. Overseas-born residents account for only 10.3%, which is 11.3 percentage points below the national average, making this one of the more Anglo-Celtic suburban communities in NSW. Ancestry data confirms this: English (1,643), Irish (485) and Scottish (369) are the three largest groups. University qualifications reach 14.9%, which is 15.2 percentage points below the national figure, consistent with the IEO decile 1 score for education and occupational access.

Tenure
Tenure splits 36.7% outright owners, 43.5% on mortgages and 19.8% renting, a higher mortgage-to-ownership ratio than is typical for an established suburb where median age is 42. The near-total dominance of separate houses at 96.7% leaves apartments at 1.4% and semi-detached at 1.9%, so buyers here are essentially always purchasing standalone homes. The 4-plus bedroom segment at 44.5% is the single largest bedroom category, above the 3-bedroom share of 40.1%, which reflects large family blocks rather than compact or downsizer product. Prices rose from $820,000 in 2024 to $852,500 in 2025, a CAGR of 4.0% over one year. Rent-to-income at 25.8% is comfortable, below the 30% stress level, even at a $835,000 median.

Economy & Employment
Healthcare leads employment at 20.8% of workers (221 people), followed by Construction at 17.2% (182), Public Administration at 7.7%, Retail at 7.6% and Education at 7.1%. The construction share is notably high compared to the NSW state average, consistent with the suburb's continued residential development activity and the nearby Central Coast growth corridor. By occupation, Clerical/Admin (244) and Community/Personal service (243) are the two largest groups, ahead of Labourers (195) and Professionals (190), which aligns with the IEO decile 1 profile. The unemployment rate is 5.0%, slightly above the national average, and the participation rate of 49.7% is low because 1,220 residents are not in the labour force, partly explained by the older median age.

Transport to Work
Car dependency is high at 94.6% driving to work, with only 1.1% walking or cycling and no public transport figure recorded, which is typical for a Central Coast suburb without heavy rail access. IRSAD decile 3 places Gwandalan in the lower-advantage tier nationally, with income at the 46.6th household income percentile and education access ranking in decile 1. No schools are recorded inside the 2.87 km2 boundary, so families rely on schools in nearby suburbs. The need-assistance rate of 7.4% (267 people) is moderate, consistent with the older demographic profile. Volunteering at 10.1% reflects reasonable community engagement. Mortgage stress is absent at 27.8% of income and rent stress is absent at 25.8%, making day-to-day costs manageable relative to household earnings.

What schools are in Gwandalan?

Is Gwandalan safe?
Crime statistics are not available for Gwandalan in this dataset. As a proxy, the suburb scores IRSD decile 4, placing it in the lower-middle range nationally for relative disadvantage. The 7.4% need-assistance rate (267 people) is moderate and consistent with an aging, established coastal community.
Is Gwandalan good for property investment?
The 10.9% vacancy rate is elevated and presents downside risk for rental investors, even though rent grew 46.3% over the decade. The 19.8% renter share is below the national average, limiting the tenant pool. Against those negatives, net internal migration of 98 people per year and 1.47% annual population growth provide steady demand, and prices rose 4.0% from 2024 to 2025.

The suburb grew from 6,756 in 2023 to 7,094 in 2025 and is forecast to reach 7,599 by 2031 under medium projections. Internal migration of 98 net arrivals per year is the primary driver, reflecting Central Coast affordability compared to Sydney.
How much development is happening in Gwandalan?
There were 25 development applications lodged in the past 12 months.

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.
