Wallacia
Half of all dwellings in Wallacia have four or more bedrooms, a ratio that sits well above the national average and explains why the median household size of 2.9 persons exceeds the national figure by 0.4. With 1,711 residents spread across 25.53 square kilometres, the density of 67 people per square kilometre is strikingly low compared to metropolitan Sydney norms. Household incomes sit at the 75.2nd percentile nationally, placing Wallacia in the upper quarter for financial capacity. Construction employs 20.6% of the local workforce, more than double the share in most urban suburbs, tying the local economy directly to residential development activity in the broader Penrith corridor.

2024-2025 (PSI derived)
The median house price reached $1,075,000 in 2025, up from $942,500 in 2024, a 14.1% rise in one year that outpaced most comparable outer-Sydney markets. Separate houses account for 85.7% of stock, with apartments at only 8.9%, so detached family homes dominate supply. Four-or-more-bedroom dwellings make up 50.3% of all residences, compared to the national average where such larger homes are much less prevalent, meaning buyers get substantial floor space relative to the price. Monthly mortgage repayments average $2,500 and the mortgage-to-income ratio is 28.8%, sitting just below the 30% stress threshold, which gives buyers a moderate buffer. At $980,000 on the broader median measure, Wallacia offers larger land parcels than inner-ring Sydney for a lower per-square-metre cost.

For Investors
The rental market is small but stable: 20.6% of households rent, paying $400 per week, which against the $980,000 median produces a gross yield near 2.1%. The vacancy rate is 3.9%, slightly elevated compared to tight sub-2% markets in western Sydney, reflecting the low-density rural-residential character where rental demand is thinner. Development activity shows 16 applications in the past 12 months, a modest pipeline for a 25-square-kilometre suburb, with applications mostly for individual dwellings and sheds rather than multi-unit supply. The 17.6% annual turnover rate means a reasonable share of the market transacts each year, supporting price discovery. Income growth potential is backed by household incomes at the 75.2nd percentile nationally, providing a demand floor for rental pricing.

Demographics
The median age of 38 is 2.0 years below the national figure, indicating a relatively younger population compared to the Australian average, driven by family formation in the area. Overseas-born residents make up 13.9%, which is 7.7 percentage points below the national rate, reflecting the Anglo-leaning ancestry profile: English (590 residents) leads, followed by Maltese (161), Irish (158) and Scottish (148). University qualifications reach 18.8%, sitting 11.3 points below the national figure, consistent with a trade and services workforce where vocational training is more common than degree pathways. Average household size of 2.9 persons is 0.4 above national, supporting the concentration of larger family homes. Christianity accounts for 1,099 of the recorded religious affiliations, with Buddhism (34) and Islam (15) present in smaller numbers.

Tenure
Tenure is weighted toward ownership: 38.6% own outright and 40.8% carry a mortgage, leaving only 20.6% renting. The combined ownership rate of 79.4% is high relative to national norms, where renting typically accounts for over 30% of households. Prices rose from $942,500 in 2024 to $1,075,000 in 2025, a 14.1% annual gain. The stock is dominated by four-or-more-bedroom separate houses at 50.3%, with three-bedroom homes at 29.5%, meaning over 80% of the market serves family buyers. Apartments represent only 8.9% and semi-detached homes are negligible at 0.7%, so this is effectively a detached-house market. Mortgage-to-income sits at 28.8% and rent-to-income at 20.0%, both below stress thresholds, suggesting current residents are managing housing costs without strain.

Economy & Employment
Construction is the dominant industry at 20.6% of employed residents (100 workers), a share roughly double the national average for the sector, reflecting proximity to active greenfield development zones in the Penrith and Camden local government areas. Education employs 11.1% (54 workers) and Healthcare 10.9% (53 workers), together providing essential-services employment that is less cyclical than construction. Manufacturing adds 9.1% (44 workers) and Other Services 7.4% (36 workers). By occupation, Clerical and Admin leads at 138 workers, followed by Managers (119) and Professionals (102), with Machinery and Drivers (97) reflecting the trades-heavy employment base. The unemployment rate of 3.6% is low and the full-time employment rate of 63.5% among those employed is solid, though the participation rate of 53.4% is modest, partly because 432 residents are not in the labour force.

Transport to Work
Wallacia is almost entirely car-dependent: 89.0% of residents drive to work, compared to a national average where car use is high but not universally dominant. Public transport use is just 0.7%, reflecting limited bus and rail connectivity in this rural-residential setting. Walking or cycling accounts for 4.1%, which is respectable given the dispersed land use pattern. No schools are recorded within the suburb boundary in this dataset, so families travel to neighbouring Penrith or Mulgoa area schools. The need-for-assistance rate of 5.1% (83 residents) is close to the national average. Volunteering at 11.4% and a rent-to-income ratio of 20.0% suggest a settled community where residents are not under financial pressure, and the 82.4% share of people who remained in the same address over the year indicates high residential stability.

Is Wallacia good for property investment?
The 14.1% price rise from 2024 to 2025 (from $942,500 to $1,075,000) is a strong one-year capital growth signal.

With construction employing 20.6% of residents and low housing density, there is longer-term land development potential as the western Sydney corridor expands.

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).
