Bonnyrigg Heights
With 54.4% born overseas (32.8pp above the national average), Bonnyrigg Heights is one of western Sydney's most migration-shaped suburbs, where Vietnamese (1,269), Chinese (945), and Serbian (485) ancestries outnumber English. House prices rose 8.5% from $1,200,000 to $1,302,500 in the past year, yet personal incomes average just $568/week, roughly half the national median. The IRSD decile of 1 (most disadvantaged nationally) sits alongside 95.9% detached housing and 65.2% of homes with 4+ bedrooms, a profile where family wealth concentrates in property rather than income streams.

The median house price of $1,267,500 grew 8.5% from $1,200,000 in 2024 to $1,302,500 in 2025. Monthly mortgage repayments of $2,038 consume 24.4% of household income, below the stress threshold. Stock is overwhelmingly detached (95.9%) and large (65.2% have 4+ bedrooms). The 2.2% vacancy rate, among the lowest in this analysis, indicates tight supply. With 40.8% outright owners and 38.5% on mortgages, the suburb has strong owner-occupier anchoring. Buyers should note the IRSD decile of 1, the lowest socioeconomic ranking possible.
For Buyers
The median house price of $1,267,500 grew 8.5% from $1,200,000 in 2024 to $1,302,500 in 2025. Monthly mortgage repayments of $2,038 consume 24.4% of household income, below the stress threshold.

With 40.8% outright owners and 38.5% on mortgages, the suburb has strong owner-occupier anchoring. Buyers should note the IRSD decile of 1, the lowest socioeconomic ranking possible.
For Investors
Only 20.7% of stock is rented, but the 2.2% vacancy rate signals very tight rental supply. Weekly rent of $450 on a $1,267,500 median implies a gross yield of just 1.8%, among the weakest in western Sydney. However, 8.5% capital growth over the past year provides a strong equity return. 36 DAs in 12 months include new dwelling construction, suggesting active rebuilding. Net internal migration of -180/year means the suburb slowly loses residents, which could constrain future rental demand despite the current tight vacancy.

Detached houses at 95.9% with apartments at 0.8% and semi-detached at 3.3% make Bonnyrigg Heights one of Sydney's most homogeneous housing markets. Bedrooms skew very large: 65.2% have 4+ and 30.2% have 3, leaving under 5% in smaller formats. Outright owners (40.8%) and mortgage holders (38.5%) together account for nearly 80% of tenure. Prices rose 8.5% from $1,200,000 to $1,302,500. The IRSD decile of 1 (most disadvantaged) alongside million-dollar-plus house prices reveals a community where wealth is locked in housing assets, not liquid income.

(+79 people/yr)
EstablishedPopulation is forecast to grow modestly from 17,332 (2025) to 17,906 by 2031, at 0.46% annually (79 persons/year). Net internal migration of -180/year means the suburb loses residents domestically, offset by overseas migration of +154/year. The aging trajectory is notable: senior share grew 6.7pp and working-age share fell 2.2pp over the decade. A gentrification score of 53 (active) in the historical data has not translated into current gentrification, as the score is now 0, suggesting demographic change stalled. This growth rate ranks below the national average and well below comparable western Sydney suburbs.

Frequently Asked Questions
Is Bonnyrigg Heights a good suburb to live in?
Bonnyrigg Heights offers strong community stability (87.2% stay rate, highest in this analysis) and 95.9% detached housing at $1,267,500 median. Trade-offs include IRSD decile 1 (most disadvantaged nationally), 9.0% unemployment (double the national average), and only 5.4% volunteering, well below the 15% national norm.
What is the median house price in Bonnyrigg Heights?
The median house price is $1,267,500 (PSI derived), rising 8.5% from $1,200,000 in 2024 to $1,302,500 in 2025. Monthly mortgage repayments of $2,038 consume 24.4% of household income. Despite million-dollar-plus prices, the IRSD decile of 1 indicates this is a community with property wealth but limited incomes.
What schools are in Bonnyrigg Heights?
Bonnyrigg Heights has 3 schools: John the Baptist Catholic Primary (ICSEA 1,059, 843 students), Freeman Catholic College secondary (ICSEA 1,038, 1,411 students), and Bonnyrigg Heights Public School (ICSEA 989, 769 students). Two of 3 score above the national ICSEA benchmark of 1,000.
Is Bonnyrigg Heights safe?
Suburb-level crime data is not available. The IRSD decile of 1 (most disadvantaged nationally) and 9.0% unemployment correlate with above-average crime rates in comparable western Sydney suburbs. However, the 87.2% residential stability and 79.3% owner-occupier share suggest strong informal community oversight.
Is Bonnyrigg Heights good for property investment?
Capital growth of 8.5% in 2024-2025 is strong, but gross yield of 1.8% ($450/week on $1,267,500) is very weak. The 2.2% vacancy rate is tight, indicating undersupply for renters. Net internal outflow of 180/year and 36 DAs adding supply may gradually ease this tightness. Best for equity growth, not rental income.
How is Bonnyrigg Heights's population changing?
Population is forecast to grow at just 0.46% annually (79 persons/year) to 17,906 by 2031. The suburb loses 180 residents per year to internal migration while gaining 154 from overseas.

What languages are spoken in Bonnyrigg Heights?
With 54.4% born overseas (32.8pp above national average), Bonnyrigg Heights is among Sydney's most diverse suburbs.

How much development is happening in Bonnyrigg Heights?
36 development applications were lodged in the past 12 months, primarily new dwelling construction, demolition/rebuild projects, and swimming pool additions. For a suburb of 7,369 census population, this represents moderate activity concentrated in knock-down-rebuild cycles on existing lots.
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.
