SA 5017 Census 2021 + Live DA Data

Osborne

The suburb remains detached-house led, with 84.7% of dwellings separate houses, while its 1,951 residents have a median age of 41, just 1 year above the national figure. A 6.55% annual growth trend points to a high-growth setting, with migration described as Balanced rather than driven by one channel. Compared with nearby Taperoo and North Haven, Osborne gives buyers another established coastal option, but the price rise deserves careful testing against income. Household income sits at the 33.9th national percentile, making the recent acceleration more notable than its income position.

Osborne's typical buyer is choosing a three-bedroom format: 66.5% of homes have 3 bedrooms, and 84.7% are separate houses. Mortgage repayments are $1,468 monthly; mortgage costs equal 25.4% of household income and rent equals 22.5%, with neither flagged for stress. Ownership is split between 27.2% outright owners, 39.9% mortgage holders and 32.2% renters. Compared with apartment-oriented markets, Osborne suits buyers seeking conventional house layouts, while the 2.3-person average household means a three-bedroom purchase may provide flexibility beyond immediate family needs.

For Buyers

Osborne's typical buyer is choosing a three-bedroom format: 66.5% of homes have 3 bedrooms, and 84.7% are separate houses. Mortgage repayments are $1,468 monthly; mortgage costs equal 25.4% of household income and rent equals 22.5%, with neither flagged for stress.

Compared with apartment-oriented markets, Osborne suits buyers seeking conventional house layouts, while the 2.3-person average household means a three-bedroom purchase may provide flexibility beyond immediate family needs.

For Investors

Osborne presents a mixed but potentially active rental case. Renting accounts for 32.2% of occupied dwellings, weekly rent is $300 and vacancy is 5.4%, giving landlords a tenant pool with more available stock than a tightly constrained market. Development activity reached 36 applications in 12 months, including land division, additions and alterations, pointing to ongoing property turnover. The 6.55% annual growth trend is supportive, while migration is Balanced, so the investment case depends on dwelling quality, tenant appeal and purchase discipline rather than one migration source.

Transport to Work

Osborne is compact at 1.42 square kilometres, with 1,951 residents and density of 1,371.7 people per square kilometre. Daily travel is strongly car-based: 79.9% drive as the main mode, compared with 3.9% using public transport, while 8.6% work from home and 2.0% walk or cycle. That pattern suits households with reliable vehicle access but can make commute costs and parking more important than in a transit-led suburb. Families should check nearby government and non-government school options, exact enrolment zones and travel times against each address, because practical access can differ across the surrounding network. Osborne recorded 141 offences, equal to 72.3 incidents per 1,000 residents, so safety should be compared with nearby areas and assessed at different times. The median age of 41 is 1 year above the national average, while volunteering is 13.3%.

Growth Outlook

Osborne's growth outlook is unusually strong, running at 6.55% annually. The area is classified as greenfield and migration is identified as Balanced, so momentum is not attributed to overseas or internal movement alone. Development activity adds a practical signal: 36 applications were recorded over 12 months, including a conventional land division, dwelling alterations and an outbuilding. Compared with a lower-growth suburb, Osborne may see stronger competition for well-presented homes because development activity and price appreciation can attract both owner-occupiers and investors. Buyers should separate the 6.55% trend from any assumption that the same rate will persist.

Frequently Asked Questions

Is Osborne a good suburb to live in?

Osborne can suit buyers who value detached housing and a settled profile. It has 1,951 residents, a median age of 41, and 79.9% car commuting. Compared with a transit-led suburb, daily life is more vehicle-dependent, so check routes, parking and local services before committing.

What schools are in Osborne?

School choice should be checked by exact address because enrolment zones can cross suburb boundaries. Compare nearby government and non-government options, travel times and year-level availability before signing a contract. Osborne covers 1.42 square kilometres, but practical access can still vary between streets and catchments.

Is Osborne safe?

Safety should be assessed with current street-level checks rather than a simple label. Osborne recorded 141 offences, equal to 72.3 incidents per 1,000 residents. Compare that rate with nearby suburbs and inspect lighting, parking areas and the route home at different times, because conditions can vary within a compact 1.42 square kilometre area.

How is Osborne's population changing?

The local population is 1,951 today, while the wider growth trend runs at 6.55% annually. Migration is classified as Balanced, and 36 development applications were recorded over 12 months. That combination points to active change without relying on a single migration source. Compared with a slower-growth suburb, Osborne may experience stronger housing demand.

What development is happening in Osborne?

Recent activity includes 36 applications in 12 months. Examples include a land division creating 2 allotments, an outbuilding and dwelling alterations. Compared with a quiet development year, this indicates active property work, but buyers should check approvals, timing and whether each proposal changes dwelling supply before relying on it.

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.
