Mount Nasura
At a median age of 44, Mount Nasura skews 4 years older than the national figure, yet 34.8% of its 2,997 residents were born overseas, a share 13.2 percentage points above national. Those two signals coexist because the suburb attracts established families rather than young renters: 96.5% of dwellings are separate houses, 53.6% have four or more bedrooms, and 88.3% of households are owners rather than tenants. Household income sits at the 61.6th percentile nationally, making this an affordable owner-occupier market where mortgage repayments average $1,733 per month against a mortgage-to-income ratio of 22.8%, well below the 30% stress threshold.

Estimated from rent (2025)
The median house price of $437,000 places Mount Nasura below the Perth metro median, giving buyers access to large detached stock at relatively modest cost. Mortgage repayments average $1,733 per month, and the mortgage-to-income ratio of 22.8% is well below the 30% stress threshold. Stock is almost exclusively detached houses (96.5%), with 53.6% having four or more bedrooms, so buyers seeking family-sized homes face strong supply. Outright owners at 38.3% outnumber renters at 11.7%, signalling a stable ownership culture. With 50.0% of households still carrying a mortgage, the suburb retains equity depth relative to its purchase price.
For Buyers
The median house price of $437,000 places Mount Nasura below the Perth metro median, giving buyers access to large detached stock at relatively modest cost. Mortgage repayments average $1,733 per month, and the mortgage-to-income ratio of 22.8% is well below the 30% stress threshold. Stock is almost exclusively detached houses (96.5%), with 53.6% having four or more bedrooms, so buyers seeking family-sized homes face strong supply. Outright owners at 38.3% outnumber renters at 11.7%, signalling a stable ownership culture. With 50.0% of households still carrying a mortgage, the suburb retains equity depth relative to its purchase price.
For Investors
The rental pool is thin: only 11.7% of households rent, well below most Perth suburbs, and weekly rent runs at $345. Against a $437,000 median that implies a gross yield around 4.1%, which is reasonable but not exceptional for Perth outer-southeast. The vacancy rate of 6.8% is elevated, suggesting current supply exceeds rental demand. Migration supports a gradual demand floor: net internal migration averages 55 residents per year and overseas migration adds 44, giving a combined 99 annual arrivals. With annual population growth at 1.07% and gentrification signals present (population up 18% since 2011), capital growth prospects are more persuasive than yield in the short term.
Demographics
The median age of 44 is 4 years above the national figure, and the senior share has risen 5.3 percentage points over the decade while the working-age share fell 2.7 points. Overseas-born residents reach 34.8%, which is 13.2 points higher than national, with English (1,481), Scottish (368), Irish (300) and Dutch (167) the dominant ancestries. University qualifications at 24.3% are 5.8 points below the national average, consistent with a trade and services employment base. Couples with children (811 families) are nearly as common as couples without children (863), reflecting a genuinely family-oriented profile rather than a retirement pocket despite the older median age.

Tenure
Separate houses make up 96.5% of dwellings, well above state and national averages, with semi-detached at 3.3% and apartments at 0.3%. The bedroom mix leans large: 53.6% of dwellings have four or more bedrooms and 41.9% have three, making single or two-bedroom stock rare. Tenure splits 38.3% outright ownership, 50.0% mortgage and 11.7% renting. Against a $437,000 median, the mortgage-to-income ratio of 22.8% is below the 30% stress threshold, meaning recent buyers remain financially comfortable. Rent-to-income of 19.7% is equally untaxing for tenants, because $345 weekly rent is low compared to Perth's inner and middle rings.

Economy & Employment
Healthcare leads local employment at 19.0% (187 workers), followed by Education at 12.8% (126) and Construction at 10.4% (103), then Retail at 8.0% and Public Administration at 7.9%. These service-sector industries explain why the IEO decile of 5 places education and occupation outcomes at the national median, even though the IER decile of 9 puts economic resources (assets and incomes) in the top tier nationally. Full-time employment runs at 61.4% and the unemployment rate is 5.6%. Household income sits at the 61.6th percentile nationally, with a weekly household income of $1,752, above the national median.

Transport to Work
Car dependency is high: 89.6% of residents drive to work and only 4.3% use public transport, above the rate of most inner-Perth suburbs but expected for outer-southeast WA. The suburb scores IRSD decile 7, above the national average for relative disadvantage, and IER decile 9 for economic resources, in the top tier nationally. Only 5.5% of residents (159 people) need daily assistance, despite a median age of 44, suggesting healthy community outcomes. Volunteering runs at 15.7%. No schools are recorded inside the suburb boundary, so families rely on neighbouring areas. Crime data is not available, but IRSD decile 7 is a reasonable indirect indicator of low-to-moderate disadvantage.

EstablishedMount Nasura has grown 12.4% over the past decade and sits at an early gentrification stage, with the broader SA2 area forecast to reach 9,569 by 2031, above the 9,050 recorded in 2025. Annual population growth of 1.07% exceeds many comparable outer-Perth suburbs. Net internal migration averages 55 residents per year and overseas migration adds 44, a balanced mix that supports consistent demand. Affordability has improved from 48.2% of income in 2011 to 40.9% in 2021, a meaningful shift compared to national trends of tightening affordability. Real income growth of 0.9% over the decade is modest, meaning price gains have outpaced local incomes, which supports further capital appreciation.

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.
