Hilbert
At a median age of 29, Hilbert is 11 years younger than the national average, one of the starkest demographic gaps in outer Perth. That youth drives the suburb's defining characteristic: 78.2% of dwellings carry a mortgage, one of the highest mortgage-belt concentrations in WA, while only 7.9% are owned outright. The household income sits at the 78th percentile nationally, meaning residents earn comfortably above average even as they shoulder large repayments. With 99.6% detached houses and 59.2% of homes having 4 or more bedrooms, the suburb is built almost entirely for growing families.

Estimated from rent (2025)
The median house price of $462,000, estimated from 2025 rent data, sits well below Perth's broader market, making Hilbert one of the more accessible options in the southeastern corridor. Monthly mortgage repayments average $1,800, producing a mortgage-to-income ratio of 20.1%, which is below the 30% stress threshold despite the high 78.2% mortgage penetration rate. The housing stock is almost entirely detached houses at 99.6%, and the bedroom profile skews large: 59.2% of dwellings have 4 or more bedrooms and 39.6% have 3, so buyers get substantial family-sized homes. At 13.9% renting, there is a modest rental pool, though the suburb is clearly oriented toward owner-occupiers.

For Investors
Weekly rent of $370 against a $462,000 median implies a gross yield near 4.2%, higher than many Perth suburbs closer to the CBD. The 4.4% vacancy rate is slightly elevated compared to the Perth metro average, suggesting modest supply competition, so investors should underwrite conservatively. The 13.9% renter share is low, which means the tenant pool is smaller than average, but the young median age of 29 indicates strong household formation that should sustain demand as the suburb matures. With 36.2% of residents born overseas, above the national figure, demand from newly arrived families provides an additional rental demand driver that is less cyclical than domestic migration.

Overseas-born residents make up 36.2% of the population, which is 14.6 percentage points above the national average, reflecting strong migrant family settlement in this outer corridor.

Economy & Employment
Healthcare is the leading employer at 18.9% of the workforce (276 workers), followed closely by Construction at 9.9% (145) and Education at 9.8% (144). Mining employs 7.3% (107 workers), meaningful for a Perth suburb and consistent with fly-in-fly-out patterns common across WA. The full-time employment rate of 72.8% is above average, and the overall participation rate of 72.0% is healthy, with just 93 unemployed residents, giving an unemployment rate of 4.3%. Household income at the 78th percentile nationally confirms that despite the outer-suburban location, residents earn substantially above the median, likely due to trade and resources sector wages. The top occupation categories are Clerical/Admin (338) and Professionals (310), followed by Community/Personal Service (281) and Machinery/Drivers (260).

Transport to Work
Car dependency is very high at 89.9% of workers commuting by car, well above the national average, and only 3.7% use public transport, reflecting the outer-suburban location with limited rail or bus access from postcode 6112. The 12.0% volunteering rate indicates moderate community engagement. Housing stress indicators are favourable: mortgage-to-income at 20.1% and rent-to-income at 17.8% are both below stress thresholds, meaning most households manage repayments comfortably relative to income. Only 3.1% of residents (124 people) need daily assistance, consistent with the young age profile. No schools are recorded within the Hilbert boundary in this dataset, so families with children rely on neighbouring suburbs for schooling options.

Frequently Asked Questions
Is Hilbert a good suburb to live in?
Hilbert suits young families seeking a large detached home at an accessible price point. The median house price is $462,000 with a mortgage-to-income ratio of 20.1%, well below the 30% stress threshold. The trade-off is strong car dependency at 89.9% of commuters driving, so the suburb suits households with private vehicles rather than those relying on public transport.
What is the median house price in Hilbert?
The median house price is $462,000, estimated from 2025 rent data. Weekly rent averages $370 and monthly mortgage repayments run about $1,800. Against household incomes at the 78th percentile nationally, that produces a mortgage-to-income ratio of 20.1%, below the 30% stress threshold.
What schools are in Hilbert?
No schools are recorded within the Hilbert boundary in this dataset, so families rely on schools in neighbouring suburbs within the postcode 6112 area. Despite this, 24.9% of Hilbert residents hold university qualifications and 9.8% of the local workforce is employed in Education, suggesting nearby school access is well established.
Is Hilbert safe?
Crime statistics for Hilbert are not available in this dataset. As an indirect indicator, housing stress metrics are low: mortgage-to-income at 20.1% and rent-to-income at 17.8% are both below stress thresholds, and only 3.1% of the 4,165 residents need daily assistance. Household income sits at the 78th percentile nationally, broadly consistent with a stable community profile.
Is Hilbert good for property investment?
Weekly rent of $370 against a $462,000 median gives an estimated gross yield near 4.2%, above many inner-Perth alternatives. The 4.4% vacancy rate is slightly elevated, which suggests modest competition for tenants. Demand drivers include strong household formation from a young median age of 29 and a 36.2% overseas-born share, both above national averages, supporting ongoing rental demand.
How is Hilbert's population changing?
Hilbert's population stands at 4,165 with a density of 453 per square kilometre across 9.19 square kilometres, leaving significant scope for further growth. The 23.5% residential turnover rate indicates active new-household formation. The young median age of 29 is 11 years below national, and 78.2% of dwellings carry mortgages, both pointing to an expanding owner-occupier base rather than a stable, long-established population.
What languages are spoken in Hilbert?
About 36.2% of residents were born overseas, which is 14.6 percentage points above the national figure. The top non-English languages are Punjabi (35 speakers), Malayalam (32), Afrikaans (22), Mandarin (18) and Hindi (13), reflecting Indian, South African and Chinese community clusters within a predominantly English-speaking suburb.
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.
