Sydney Olympic Park
At 4,848 residents, Sydney Olympic Park has a median age of 31, which is 9.0 years below the national average. The suburb is also strongly migrant-oriented, with 69.7% of residents born overseas, 48.1 percentage points above the national figure. Every recorded dwelling is an apartment at 100.0%, while 68.5% of residents rent. That combination creates a younger, more mobile profile than nearby Newington and a more compact housing market than lower-density parts of the Parramatta region. Household income sits at the 74.2nd percentile nationally, although the 61.0% turnover rate indicates a neighbourhood where residents move more frequently than they stay.

Sydney Olympic Park suits buyers seeking apartment living, professional access and a relatively compact household environment. Apartments account for 100.0% of dwellings, with two-bedroom homes making up 53.0%, compared with 36.7% of studios and one-bedroom homes. The weekly rent benchmark is $520, while the monthly mortgage figure is $2,400. Mortgage costs represent 28.1% of household income, higher than the 26.3% rent-to-income ratio, although neither measure is flagged as housing stress. Compared with nearby Wentworth Point and Newington, buyers should place more weight on building quality, strata costs, outlook and floor area than on land size because detached housing is not part of the recorded local mix.

For Investors
The suburb has a deep tenant base, with 68.5% of households renting, substantially higher than the 6.1% owning outright and the 24.5% paying a mortgage. Weekly rent is $520, but the 21.6% vacancy rate is also high, so rental income can be offset by longer letting periods, incentives or competition between similar apartments. Twenty-four development applications were recorded over 12 months, adding to the importance of assessing each building rather than treating the suburb as one market. Growth is forecast at 5.56% annually and is driven primarily by overseas migration. Compared with lower-rental-turnover markets, the opportunity is stronger tenant depth but greater vacancy sensitivity.

The housing stock is unusually concentrated: apartments represent 100.0% of dwellings, two-bedroom homes account for 53.0%, and studios or one-bedroom homes account for 36.7%. The two-bedroom share is higher than the 9.3% three-bedroom share and the 1.1% four-bedroom-plus share, confirming a market built mainly around singles, couples and smaller households. Renting dominates at 68.5%, compared with 24.5% paying a mortgage and 6.1% owning outright. The weekly rent benchmark is $520 and the monthly mortgage figure is $2,400. Mortgage costs at 28.1% of income are higher than rent costs at 26.3%, but both stress flags are false. Compared with Newington, apartment selection and strata performance matter more than detached-land scarcity.

Transport to Work
Daily living is well suited to apartment residents and people working from home. Work-from-home participation is 57.6%, higher than the 32.0% car-driver share, while public transport accounts for 4.5% and walking or cycling for 2.9%. The suburb covers 6.64 square kilometres, has 4,848 residents and a density of 730.1 people per square kilometre, so building management, shared facilities and local open space can matter more than private yards. Compared with lower-density suburban settings, the compact form can reduce household maintenance but makes noise, parking and strata rules more important. Families should check nearby school options and exact enrolment zones before committing, while safety should be assessed with current police incident information and visits at different times.

Compared with lower-density suburbs, it provides a more compact lifestyle but less detached-housing choice.
What is the median house price in Sydney Olympic Park?
A separate-house median is not meaningful for this local market because apartments account for 100.0% of recorded dwellings. Buyers should compare current apartment sales by bedroom, building and floor area instead. Two-bedroom homes represent 53.0%, higher than the 36.7% studio and one-bedroom share.

Is Sydney Olympic Park safe?
A definitive safety rating requires current incident information, so compare NSW Police mapping with an inspection at different times of day.

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.
