Rosslyn Park
Its 1,469 residents have a median age of 49, which is 9 years above the national median, while university attainment is 59.2%, or 29.1 percentage points higher than nationally. For buyers comparing Rosslyn Park with nearby Kensington Gardens or St Georges, the 82.9% separate-house share, 55.7% outright ownership and 84.0% staying-put rate point to an established, low-turnover setting. Overseas-born residents account for 39.4%, adding cultural variety without changing the suburb's strongly premium housing profile.

Rosslyn Park suits buyers prioritising established detached housing, but the entry price is a major consideration. That sharp increase raises the deposit hurdle, even though the monthly mortgage figure is $2,600 and the mortgage-to-income measure is 27.0%, with no mortgage-stress flag. Housing is mostly conventional family stock: 82.9% separate houses, including 47.0% with 4 or more bedrooms and 38.0% with 3 bedrooms. Compared with nearby Kensington Gardens, buyers should weigh Rosslyn Park's stronger detached-house orientation against its premium price and limited rental share of 13.7%.

Compared with nearby Kensington Gardens, buyers should weigh Rosslyn Park's stronger detached-house orientation against its premium price and limited rental share of 13.7%.
For Investors
The investment case is defensive but yield-sensitive because Rosslyn Park is dominated by owners rather than tenants. Only 13.7% of households rent, below the 55.7% owning outright and 28.7% buying with a mortgage, so tenant demand may be narrower than in more rental-oriented suburbs. Weekly rent is $398 and vacancy is 6.5%, a combination that warrants careful property selection and realistic leasing assumptions. The median house price increased 14.5% between 1Q 2025 and 1Q 2026, but that capital result also makes acquisition more expensive. Development activity reached 22 applications in 12 months, mainly involving alterations and additions, which indicates ongoing renewal rather than a clear wave of new dwelling supply. Balanced migration supports a measured outlook compared with a high-growth corridor.

Rosslyn Park's housing market is premium, detached and strongly owner-held.

Tenure is led by outright ownership at 55.7%, followed by mortgages at 28.7% and renting at 13.7%. The bedroom mix reinforces the family-house pattern: 47.0% have 4 or more bedrooms and 38.0% have 3.

Construction accounts for 6.5% or 34 workers, while retail represents 5.7% or 30.

Household income sits at the 84.3 percentile, above the midpoint, but SEIFA results are more mixed: IEO and IRSAD are decile 5, while IER and IRSD are decile 4. That contrast suggests strong incomes for many households but less uniform advantage across the whole suburb.

Transport to Work
Rosslyn Park is compact, with 1,469 residents across 0.82 square kilometres and a density of 1,781.7 people per square kilometre. Daily travel is strongly car-based: 72.2% drive as car commuters, compared with 5.0% using public transport and 3.4% walking or cycling, while 16.3% work from home. This pattern matters because households may value private vehicle access more than a transit-led lifestyle. Recorded crime totals 28 incidents, equal to 19.1 per 1,000 residents, supporting the suburb's low-crime profile. Families should check nearby school options, sector, travel times and enrolment zones against the exact address, since practical access can vary across boundaries. SEIFA results are moderate rather than uniformly high: IRSAD is decile 5, above the IRSD and IER results of decile 4, while IEO is also decile 5. That mixed profile fits a settled suburb with strong professional incomes but varied household circumstances.

Growth Outlook
Rosslyn Park has an established profile, with growth running at 1.37% annually and migration classified as Balanced. Across the wider area, population change is 17.4% over 10 years, but the trajectory is Aging: the senior share has increased by 5.4 percentage points while the young share has fallen by 3.9 points. Affordability worsened from 21.2 in 2011 to 29.5 in 2021, and rent growth of 83.0% was higher than real income growth of 6.9%, creating pressure for younger entrants. Gentrification is rated 22 at the Early signs stage, while the shift profile records a score of 63 and Active, indicating renewal signals within an established base. The combination of 1.37% annual growth and Balanced migration points to gradual change rather than a sudden population surge.

Frequently Asked Questions
Is Rosslyn Park a good suburb to live in?
Rosslyn Park suits households seeking established detached housing, a low-crime profile and a quieter resident base. It has 1,469 residents, a median age of 49 and a crime rate of 19.1 per 1,000. Compared with more transient areas, the 84.0% same-address rate supports a settled atmosphere, although 72.2% car commuting makes vehicle access important.
What schools are in Rosslyn Park?
Families should check the exact address for nearby school options, sector, enrolment zone and travel time before buying. Rosslyn Park covers 0.82 square kilometres, but a compact footprint does not guarantee that the nearest campus is available for enrolment. Confirm current government, Catholic and independent options directly and compare catchment rules with the property location.
Is Rosslyn Park safe?
Rosslyn Park records 28 total crime incidents and a rate of 19.1 incidents per 1,000 residents. That supports its low-crime identity, although conditions can vary by street and over time. Compare the 19.1 rate with current local police and council updates, and inspect lighting, traffic and pedestrian conditions around any property being considered.
How is Rosslyn Park's population changing?
Growth is gradual, with an annual trend of 1.37% and a Balanced migration driver. Across the wider area, population change over 10 years is 17.4%, while the trajectory is Aging. The senior share has risen 5.4 percentage points and the young share has fallen 3.9 points, so change is more likely to reflect household aging and gradual renewal than rapid family influx.
What development is occurring in Rosslyn Park?
There were 22 development applications in the past 12 months. The examples are mainly alterations, additions, repairs and refurbishment of existing dwellings or structures rather than clearly identified new housing supply. Compared with a greenfield growth area, this points to incremental renewal, so buyers should check individual approvals, heritage controls and construction impacts.
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.
