For Investors
St Peters has a substantial rental base, with 45.8% of households renting and weekly rent at $650. Renting is higher than outright ownership at 18.3% and mortgage tenure at 35.1%, creating an established pool of tenant households. Vacancy is 9.3%, so landlords should allow for tenant choice rather than assume automatic leasing pressure. Development activity reached 42 applications in 12 months, including attached-dwelling, demolition and subdivision proposals, which can refresh stock but also add construction and competition risk. The trend is 1.0% annually and overseas migration is the primary driver. With no sale price stated, assess yield, strata, vacancy and cash flow at property level.

Frequently Asked Questions
Is St Peters a good suburb to live in?
St Peters suits buyers and renters who value compact inner-west living, with 2,098.2 people per sq km, 61.8% university educated and 65.5% working from home. The trade-off is mixed housing stock, with 39.1% apartments and 45.8% renting, so it is more urban than a detached-house suburb.
What is the median house price in St Peters?
A single current median house price should be checked against recent settled sales. St Peters has 22.5% separate houses, 37.6% semi-detached homes and 39.1% apartments, so dwelling mix makes one house figure less representative than in a detached-house suburb.
What schools are in St Peters?
St Peters Public School is the named local school, a government primary school. Families should confirm the catchment and available places for the exact address, especially because 45.8% of dwellings have 2 bedrooms and 39.1% are apartments. Nearby choices may sit outside the suburb boundary, so check NSW enrolment rules before signing.
Is St Peters safe?
A current suburb-level crime rate is not stated, so check NSW Police or BOCSAR by address and offence type before deciding. St Peters covers only 1.73 sq km but has 2,098.2 people per sq km, meaning street context, lighting and nearby activity deserve more attention than a single suburb-wide impression.

There were 42 development applications in 12 months, while the trend is 1.0% annually and overseas migration is the primary driver.

St Peters has 3,629 residents today. Across the wider area, population change is 15.1% over 10 years, with an annual trend of 1.0% and overseas migration the primary driver. The trajectory is Mixed, so change is more measured than a high-growth corridor rather than a sign of sudden expansion.

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 education open registers (school locations), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
