WA 6018 Census 2021 + Live DA Data

Gwelup

Detached houses make up 85.2% of dwellings here, and that scarcity of anything smaller shapes everything else about the suburb. Household income sits in the 94.4th percentile nationally at $2,658 a week, and Gwelup scores decile 10 on three of four SEIFA indexes (IRSAD, IRSD and IER), the top advantage tier. The population of 5,391 has grown more than 22% since 2011, yet the profile is aging, with the senior share up 5.9 points and a median age of 42, two years above national. University qualifications reach 45.5%, which is 15.4 points above the national figure, reinforcing a settled professional base across a compact 2.94 km2.

The estimated $713,000 median house price reflects a market built almost entirely around large family homes: 62.3% of dwellings have four or more bedrooms and only 12.8% have two or fewer, so buyers chasing a smaller footprint have little to choose from. Separate houses account for 85.2% of stock against just 3.0% apartments. Monthly mortgage repayments average $2,600, producing a mortgage-to-income ratio of 22.6%, well below the 30% stress threshold thanks to incomes in the 94.4th percentile. Mortgage holders (47.0%) slightly outnumber outright owners (43.1%), a sign of active recent buying rather than a fully settled, debt-free base, and renters are scarce at 9.9%.

For Investors

With only 9.9% of households renting and weekly rent at $600, the tenant pool is shallow, which limits the suburb as a yield play. Against the $713,000 median, that rent implies a gross yield near 4.4%, healthier than premium inner-city markets but constrained by thin supply. The vacancy rate of 4.0% sits at the higher end and points to soft rental demand rather than scarcity. Demand support comes mainly from migration: net overseas inflow adds about 280 residents a year while internal migration adds 56. Development activity is modest at 10 applications in 12 months, mostly single-house additions rather than new supply, so the investment case rests on capital growth, backed by 22% population gains since 2011, more than on rental volume.

Demographics

The median age of 42 is 2.0 years above the national figure, and the trajectory is aging: the senior share rose 5.9 points while the working-age share fell 5.1 points over the decade. Overseas-born residents reach 28.5%, which is 6.9 points above national. Ancestry leans Anglo-Celtic and southern European, led by English (2,184), Scottish (541), Irish (531) and Italian (527), and the top non-English languages are Mandarin (59 speakers), Italian (38) and Cantonese (20). University qualifications at 45.5% run 15.4 points above national. Average household size is 2.8, which is 0.3 above national, consistent with a family profile where couples with children (2,291) far outnumber couples without (1,002).

Tenure tilts toward buyers carrying debt: 47.0% hold a mortgage, 43.1% own outright and only 9.9% rent. That mortgage majority, unusual in a high-advantage suburb, signals a base of working families still paying down large homes rather than retired outright owners. The stock is 85.2% separate houses and just 3.0% apartments, with 8.9% semi-detached, and four-or-more-bedroom homes dominate at 62.3% against three-bedroom at 24.9%. Despite the estimated $713,000 median, affordability stays comfortable because both mortgage-to-income and rent-to-income sit at 22.6%, well below the 30% stress mark, supported by household income in the 94.4th percentile. Affordability has held broadly stable, easing only slightly from 48.6% in 2011 to 47.1% in 2021.

Economy & Employment

The workforce concentrates in services rather than the resource jobs typical of WA: Healthcare leads at 16.0% (306 workers), Professional/Tech follows at 15.0% (288) and Education at 12.1% (231), with Construction at 9.7% and Mining a smaller 8.5%. By occupation, Professionals (903) and Managers (453) make up the largest groups, which aligns with the decile 9 IEO score for education and occupation. Unemployment is low at 2.9% and the full-time employment rate is 62.2%. Participation reads 60.6%, held down by 1,352 residents not in the labour force, consistent with the aging profile. The suburb scores decile 10 on IER for economic resources, reflecting the high incomes and detached-house wealth.

Transport to Work

The suburb is heavily car-dependent: 87.8% of commuters drive, while only 4.4% take public transport and 2.6% walk or cycle, both below national norms and a function of the low-density, detached layout at 1,836 residents per km2. Gwelup earns decile 10 on IRSAD, the top advantage tier nationally, and decile 10 on IRSD for relative disadvantage, so very few residents face deprivation, though 6.3% (326 people) still need daily assistance given the older median age of 42. Volunteering runs at 18.5%. No schools are recorded inside the 2.94 km2 boundary in this dataset, so families rely on institutions in neighbouring suburbs, a practical trade-off in a small, residential pocket.

Established

Gwelup is classified established but still expanding: annual population growth runs 1.31% and the 10-year change reaches 19.4%, with signals showing acceleration from a 4% pace toward 17%. Overseas migration is the primary driver, adding about 280 residents a year, well above the net internal gain of 56. The gentrification stage reads early signs with a score of 39, supported by the more than 22% population rise since 2011 and steady inflows. The trajectory is aging, the senior share up 5.9 points against a 5.1-point fall in working-age residents, so growth is coming more from migration than from a younger demographic. Real incomes grew 4.4% over the decade, a modest gain relative to the population increase.

Frequently Asked Questions

Is Gwelup a good suburb to live in?

Gwelup ranks in decile 10 on IRSAD, IRSD and IER, the top advantage tier nationally, with household income in the 94.4th percentile. University qualifications reach 45.5%, 15.4 points above national. The main trade-offs are an estimated $713,000 median house price and heavy car dependence, with 87.8% of commuters driving.

What is the median house price in Gwelup?

The estimated median house price is $713,000, with weekly rent averaging $600 and monthly mortgage repayments about $2,600. That gives a mortgage-to-income ratio of 22.6%, well below the 30% stress threshold thanks to household income in the 94.4th percentile nationally.

What schools are in Gwelup?

No schools are recorded inside the 2.94 km2 Gwelup boundary in this dataset, so families rely on schools in neighbouring suburbs. The local population is highly educated, with university qualifications at 45.5%, which is 15.4 points above the national figure.

Is Gwelup safe?

Detailed crime statistics are not available for Gwelup in this dataset. As an indirect indicator, the suburb scores decile 10 on the IRSD index of relative disadvantage, the highest tier, and only 6.3% of its residents need daily assistance, both consistent with a low-disadvantage area.

Is Gwelup good for property investment?

Rent of $600 a week against an estimated $713,000 median gives a gross yield near 4.4%. Only 9.9% of households rent and the vacancy rate is 4.0%, so the tenant pool is shallow. Net overseas migration of about 280 a year supports demand, but returns lean on capital growth more than yield.

How is Gwelup's population changing?

Population growth runs 1.31% annually with a 19.4% rise over 10 years and more than 22% since 2011. Growth is driven mainly by overseas migration of about 280 a year. The profile is aging, with the senior share up 5.9 points and the working-age share down 5.1 points over the decade.

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.
