Winthrop
Almost the entire dwelling stock here is detached: 99.1% are separate houses and 90.7% carry four or more bedrooms, an unusually uniform fabric for a 3.48 km2 pocket south of the Swan River. The result is a settled, family-scale suburb where 55.4% of homes are owned outright and household income sits in the 88.6th percentile nationally. Yet the population is aging fast, with a median age of 45, fully 5.0 years above the national figure, and a senior share that climbed 10.8 points over the decade while overall numbers slipped 3.0%. Migration tells the story: overseas arrivals add about 126 residents a year against a net internal outflow of 35, and nearly half of residents (47.9%) were born overseas.

The median house price of $643,000 buys into a market built almost entirely for families, with 99.1% separate houses and 90.7% of dwellings holding four or more bedrooms. Smaller options barely exist, as only 8.2% are three-bedroom and 0.9% two-bedroom, so downsizers and first-home buyers have little to choose from. Affordability has actually improved over the decade, easing from 80.6% to 71.5%, because incomes outpaced price growth. Monthly mortgage repayments average $2,317 and the mortgage-to-income ratio sits at 23.0%, comfortably below the 30% stress threshold despite the family-sized stock. With 55.4% of homes owned outright and only 33.9% carrying a mortgage, buyers are competing against established, debt-free owners who rarely sell, which keeps turnover low at 17.0%.

For Investors
The rental story here is thin by design: only 10.7% of homes are rented while 55.4% are owned outright, so the tenant pool is small in a stock that is 99.1% separate houses. Weekly rent of $545 against the $643,000 median implies a gross yield near 4.4%, healthier than most premium Perth suburbs because prices stayed restrained while rents grew 9.0%. The vacancy rate of 5.9% points to slightly soft demand rather than scarcity, and development is negligible with zero applications recorded in the past 12 months, meaning supply will not expand. Demand support leans entirely on overseas migration, which adds 126 residents a year and offsets a net internal outflow of 35. Rent-to-income at 23.5% leaves tenants room, but the small renter base and aging population temper the growth case.

Demographics
The median age of 45 runs 5.0 years above the national figure, and the trajectory is firmly aging: the senior share rose 10.8 points over the decade while the working-age share fell 3.0 points. Overseas-born residents reach 47.9%, which is 26.3 points above national, giving the suburb a strongly international character. Chinese ancestry leads at 1,747, ahead of English at 1,550, and the top non-English languages are Mandarin (251 speakers) and Cantonese (126), consistent with a long-established East Asian community. University qualifications hit 56.8%, fully 26.7 points above national, and average household size is 3.0, which is 0.5 above national and reflects the family-with-children base. Christianity (3,250) leads religion, with Buddhism (329) a notable second that mirrors the ancestry mix.

Tenure
Tenure leans heavily toward established ownership: 55.4% own outright, 33.9% carry a mortgage and just 10.7% rent. Outright owners outnumbering mortgage holders by a wide margin signals long-held, debt-free wealth rather than a churn of new buyers, which keeps turnover low at 17.0%. The stock is remarkably uniform at 99.1% separate houses, with apartments effectively absent, and 90.7% of dwellings hold four or more bedrooms against only 8.2% three-bedroom. The median house price is $643,000, and rent grew 9.0% over the period while affordability improved from 80.6% to 71.5%. Mortgage-to-income at 23.0% and rent-to-income at 23.5% both sit below the 30% stress threshold, a comfort that reflects household income in the 88.6th percentile rather than cheap housing.

Economy & Employment
The local workforce is concentrated in stable, credential-heavy sectors: Healthcare leads at 16.1% (359 workers), Education follows at 13.8% (307) and Professional/Tech at 13.0% (289), with Retail at 7.1% and Public Admin at 6.8%. By occupation, Professionals (1,066) and Managers (461) dominate, which aligns with the decile 9 IEO score for education and occupation and the 56.8% university qualification rate. Unemployment is moderate at 4.9% and the full-time rate is 58.9%, but participation reads just 60.0% because the aging profile leaves 1,779 residents out of the labour force. The IER index of economic resources scores decile 10, the top tier nationally, driven by the 55.4% outright ownership and family incomes of $2,405 a week. Real income growth was essentially flat at -0.1% over the decade.

Transport to Work
Daily life is car-centred: 86.3% drive to work while only 5.1% use public transport and 1.7% walk or cycle, well below the active-transport share of denser suburbs, a function of the detached, low-density layout at 1,730 residents per km2. The suburb scores decile 9 on IRSAD and decile 10 on IRSD for relative disadvantage, near the top advantage tier nationally, so very few residents face deprivation. Volunteering runs at 20.2% and only 3.9% (231 people) need daily assistance despite the older median age of 45. No schools are recorded inside the 3.48 km2 boundary in this dataset, so families rely on institutions in neighbouring suburbs, a practical trade-off for the quiet, residential character. Housing stress is low, with mortgage-to-income at 23.0%, below the national stress threshold.

Population Forecast
-0.06%/yr
(-4 people/yr)
EstablishedWinthrop is contracting slowly: annual population change registers -0.06%, roughly four fewer residents a year, and the 10-year trend is down 3.0%, classifying it as an established, slow-growth suburb. Medium forecasts hold the population near 6,340 through 2031, a gentle decline from the 6,641 recorded in 2025. The only positive driver is overseas migration at 126 a year, which partly offsets a net internal outflow of 35 and the aging base where the senior share rose 10.8 points. The gentrification stage reads not gentrifying with a score of 0, fitting a suburb already at decile 9 advantage with little room to climb. Affordability improving from 80.6% to 71.5% reflects income gains rather than fresh demand, so the outlook is stability rather than expansion.

Frequently Asked Questions
Is Winthrop a good suburb to live in?
Winthrop scores decile 9 on IRSAD and decile 10 on IRSD, near the top advantage tier nationally, with household income in the 88.6th percentile. University qualifications reach 56.8%, 26.7 points above national, and 55.4% of homes are owned outright. The main trade-offs are an aging population and car dependence, with 86.3% driving to work.
What is the median house price in Winthrop?
The median house price is $643,000, with weekly rent averaging $545 and monthly mortgage repayments around $2,317. That gives a mortgage-to-income ratio of 23.0%, below the 30% stress threshold. Affordability improved from 80.6% to 71.5% over the decade as incomes outpaced price growth.
What schools are in Winthrop?
No schools are recorded inside the 3.48 km2 Winthrop boundary in this dataset, so families rely on schools in neighbouring suburbs. The local population is highly educated, with university qualifications at 56.8%, which is 26.7 points above the national figure.
Is Winthrop safe?
Detailed crime statistics are not available for Winthrop in this dataset. As an indirect indicator, the suburb scores decile 10 on the IRSD index of relative disadvantage, the highest tier, and only 3.9% of its 6,020 residents need daily assistance, both consistent with a low-disadvantage area.
Is Winthrop good for property investment?
Rent of $545 a week against a $643,000 median gives a gross yield near 4.4%, stronger than most premium Perth suburbs. But only 10.7% of homes are rented and the vacancy rate is 5.9%, so the tenant pool is small. Demand rests on overseas migration of 126 residents a year against -3.0% population change.
How is Winthrop's population changing?
Population is declining slowly, with annual change at -0.06% and a 3.0% fall over 10 years to about 6,641 in 2025. The profile is aging, as the senior share rose 10.8 points and the working-age share fell 3.0 points over the decade. Overseas migration of 126 a year is the only positive driver.
What languages are spoken in Winthrop?
About 47.9% of residents were born overseas, 26.3 points above the national figure. English is the dominant language, with Mandarin (251 speakers) and Cantonese (126) the most common non-English languages, reflecting a strongly international community led by Chinese ancestry at 1,747 residents.
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.
