Dalyellup
Population grew 37.4% over the decade and continues at 3.05% annually (338 persons/year), making Dalyellup one of Western Australia's fastest-expanding established suburbs outside Perth. Yet this growth is aging from the inside: the young share contracted by 7.4 percentage points, the sharpest youth decline in this batch, while the senior share grew by 6.2 points. At an estimated $440,000 median, the suburb remains affordable, and the mortgage-to-income ratio of 19.4% is one of the lowest nationally, reflecting household incomes at the 77.7th percentile against a low price base. Healthcare employment at 22.8% dominates the local economy, well above the national average.

The estimated $440,000 median makes Dalyellup one of the most accessible suburbs in this dataset, with monthly mortgage repayments of $1,733 producing a mortgage-to-income ratio of just 19.4%, well below the 30% stress benchmark. Detached houses at 94.8% dominate, and 71.4% of homes have four or more bedrooms, meaning large family homes are the standard format rather than a premium product. Mortgage holders at 53.3% exceed outright owners at 18.0%, typical for a young suburb where most buyers purchased recently. Car dependence at 89.2% is high, with public transport at 2.2%, reflecting Dalyellup's position as a regional satellite of Bunbury.

For Investors
Renters at 28.8% provide a moderate tenant pool, and median weekly rent of $350 against a $440,000 estimated median produces a gross yield around 4.1%, above the national average. The vacancy rate of 6.5% is elevated, suggesting some rental oversupply. No development applications were lodged in the past 12 months, but the 3.05% population growth rate ensures ongoing demand. Migration is balanced: internal net arrivals average 62/year and overseas arrivals 74/year. The gentrification score of 26 (early signs) reflects population growth and internal migration rather than income-driven displacement. Medium projections forecast 13,490 by 2031, a 22% increase from 2025.

Population Forecast
+3.05%/yr
(+338 people/yr)
EstablishedPopulation grows at 3.05% per year (338 persons), well above the national average, reaching an estimated 11,081 in 2025. The 10-year change of 37.4% confirms sustained expansion. Migration is balanced between internal (62/year) and overseas (74/year) sources. Despite the growth, the young share contracted sharply by 7.4 percentage points, meaning Dalyellup's first-generation families are aging in place while fewer new young families arrive. Gentrification early signs (score 26) stem from population and migration patterns. Medium projections forecast 13,490 by 2031, maintaining the roughly 3% annual growth rate.

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.
