Two Rocks
A 77.4% population surge over the past decade marks Two Rocks as one of WA's fastest-growing coastal fringe suburbs, yet the median house price sits at an estimated $434,000, well below the Perth state median. The suburb covers 51.82 km2 at a density of just 73.8 persons per km2, and 99.5% of dwellings are separate houses, making it almost purely detached housing. Household income ranks at the 47.9th percentile nationally, while the IRSAD decile sits at 4, indicating below-average socioeconomic advantage. The vacancy rate of 13.2% is unusually high and reflects a suburb where land releases have outpaced occupancy, a pattern common in new coastal corridors north of Perth.

At an estimated $434,000 median house price, Two Rocks is more affordable than the Perth metropolitan average, making it a realistic entry point for families priced out of closer suburbs. Monthly mortgage repayments average $1,800, and the mortgage-to-income ratio of 27.2% stays below the 30% stress threshold. Stock is almost entirely separate houses at 99.5%, and 56.5% of homes have 4 or more bedrooms, suiting larger households. The ownership structure leans toward mortgagees at 55.2%, with 27.8% owning outright and 16.9% renting.
For Buyers
At an estimated $434,000 median house price, Two Rocks is more affordable than the Perth metropolitan average, making it a realistic entry point for families priced out of closer suburbs.

The ownership structure leans toward mortgagees at 55.2%, with 27.8% owning outright and 16.9% renting.
For Investors
The 13.2% vacancy rate is the headline risk, signalling supply that has outpaced near-term demand. Weekly rent of $330 against a $434,000 median implies a gross yield around 3.9%, below typical WA coastal expectations given the high vacancy. The renter share of 16.9% is low, so most demand is owner-occupier driven. Annual population growth of 3.41% and net internal migration of 236 persons per year are genuine tailwinds. Rent grew 17.9% over the measured period. The investment case rests on capital growth from sustained inflow rather than current yield.

Demographics
The median age of 39 is 1.0 year below the national figure, consistent with a suburb drawing young families. Overseas-born residents reach 30.8%, which is 9.2 percentage points above the national average, reflecting WA's mining-sector migration. Ancestry is predominantly English (1,781), Irish (364) and Scottish (341), with Afrikaans the most spoken non-English language at 21 speakers. University qualifications at 14.2% run 15.9 percentage points below national, a gap explained by the dominance of trade and blue-collar occupations. Couples with children (1,447 families) outnumber couples without children (777) by nearly 2 to 1.

The stock is 99.5% separate houses, above almost any comparable Perth suburb, with semi-detached at 0.3% and no recorded apartments. Large homes dominate: 56.5% have 4 or more bedrooms, compared to a national median closer to 3. Tenure splits into 27.8% owned outright, 55.2% mortgaged and 16.9% renting, a mortgage-belt profile reflecting recent land releases. Rent-to-income at 21.6% and mortgage-to-income at 27.2% both stay below stress thresholds. The 13.2% vacancy rate is elevated and warrants monitoring, as it can compress rents and resale values if supply continues to outpace demand.

Economy & Employment
Mining (15.6%) and Healthcare (15.5%) are tied as the top industries, followed by Construction (13.0%), Education (11.3%) and Retail (6.6%). The mining share reflects FIFO or commuter workers rather than local operations. By occupation, Labourers (199), Professionals (194), Community and Personal service (193) and Machinery and Drivers (191) are nearly equal, a spread typical of a mixed working-class suburb. Unemployment of 7.8% is elevated above the national average, and the participation rate of 53.6% is below national levels because 975 residents are not in the labour force. The IEO decile of 2 places Two Rocks in the bottom quintile nationally for education and occupation advantage.

Transport to Work
Car dependency at 87.6% of commuters is well above the national average, because public transport reaches only 4.0% of residents, reflecting limited rail and bus coverage north of Perth. No schools are recorded inside the suburb boundary, so families commute to Yanchep or nearby areas. Volunteering runs at 13.6%, a moderate rate. The IRSAD decile of 4 places Two Rocks below the national median for socioeconomic advantage. Rent-to-income at 21.6% and mortgage-to-income at 27.2% both stay below stress thresholds, so housing costs remain manageable for current residents despite the rapid growth of the past 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).
