SA 5091 Census 2021 + Live DA Data

Banksia Park

Three in every ten Banksia Park homes are owned outright and mortgage repayments sit at just 19.9% of income, well below the 30% stress threshold, making this one of Adelaide's more financially settled northeastern suburbs. The median house price reached $845,000 in Q1 2026, up 9.7% from $770,000 a year earlier, which is notable for a suburb classified as not gentrifying. On SEIFA, IRSD decile 8 confirms low disadvantage, while IEO decile 6 places education and occupation attainment at the national median. Nearly all dwellings, 99.7%, are separate houses on a 1.99 km2 footprint, reflecting a classic postwar detached-house suburb rather than a corridor for new apartment supply.

The $845,000 median house price in Q1 2026 represents a 9.7% rise from $770,000 in Q1 2025, a sharp one-year move for an established area. Monthly mortgage repayments average $1,550, giving a mortgage-to-income ratio of 19.9%, which is comfortably below the 30% stress benchmark compared to many Adelaide metropolitan suburbs. Stock is almost entirely separate houses at 99.7%, with three-bedroom homes dominant at 63.7% and four-plus bedroom at 32.6%. Only 10.5% of residents rent, meaning buyer competition is mainly between owner-occupiers rather than investors. With 38.8% owning outright, the suburb carries a low-debt profile that tends to dampen forced selling and support price floors during downturns.

For Buyers

The $845,000 median house price in Q1 2026 represents a 9.7% rise from $770,000 in Q1 2025, a sharp one-year move for an established area. Monthly mortgage repayments average $1,550, giving a mortgage-to-income ratio of 19.9%, which is comfortably below the 30% stress benchmark compared to many Adelaide metropolitan suburbs. Stock is almost entirely separate houses at 99.7%, with three-bedroom homes dominant at 63.7% and four-plus bedroom at 32.6%. Only 10.5% of residents rent, meaning buyer competition is mainly between owner-occupiers rather than investors. With 38.8% owning outright, the suburb carries a low-debt profile that tends to dampen forced selling and support price floors during downturns.

For Investors

The investor case is narrow but stable. Weekly rent of $350 against an $845,000 median implies a gross yield around 2.2%, below the national average for detached houses. The 4.5% vacancy rate is moderate, above the typical healthy benchmark of 3%, suggesting demand is adequate rather than heated. Net internal migration runs at negative 74 persons per year while overseas migration adds 12 annually, so population support for rental demand is limited. Development activity reached 50 applications in 12 months, mostly subdivision and single-dwelling works rather than unit supply, which keeps the separate-house stock constrained. Rent grew 14.6% over the observed period, outpacing real income growth of 0.2%, which gradually improves yield dynamics for holders.

Demographics

The median age is 41, matching the national figure almost exactly at 1.0 years above it. Overseas-born residents account for 18.4% of the population, 3.2 percentage points below the national average, which aligns with the dominant Anglo-Celtic ancestry mix: English (1,679 residents), Scottish (333), Irish (283) and German (272) lead the count. University qualifications reach 28.6%, which is 1.5 points below national. Average household size of 2.6 is marginally above national, reflecting the high share of family households, with couples with children (1,253) outnumbering couples without children (799). The volunteering rate is 20.0%, above typical metropolitan norms, and the aging trajectory, with the senior share rising 3.5 points over the decade, will gradually shift the family-household balance.

Banksia Park is as close to a pure detached-house suburb as Adelaide produces: 99.7% separate houses with semi-detached at 0.3% and apartments negligible. Tenure is split firmly toward ownership, with 38.8% owning outright and 50.7% carrying a mortgage, leaving only 10.5% renting, far below the national renter share. Three-bedroom homes comprise 63.7% of stock and four-plus bedroom homes 32.6%, so the inventory skews larger than average. The median house price rose from $770,000 to $845,000 between Q1 2025 and Q1 2026, a 9.7% gain. Mortgage-to-income at 19.9% and rent-to-income at 19.5% both sit below the 30% stress threshold compared to the SA average, indicating current owners and renters are not financially stretched by housing costs.

Economy & Employment

Healthcare leads the local employment mix at 19.9% (219 workers), followed by Education at 15.0% (165) and Construction at 12.6% (138). Public Administration accounts for 10.1% and Professional/Tech for 7.2%, giving the workforce a public-sector and service-industry lean that is common across suburban Adelaide. By occupation, Professionals lead at 350 workers, ahead of Clerical/Admin (233) and Community/Personal (206). The unemployment rate is 4.1% against a participation rate of 60.7%, while the full-time employment rate is 61.0%. SEIFA IER decile 9 signals high economic resources, a contrast with IEO decile 6, because home ownership and mortgage-free tenure inflate asset-based resource measures even where occupational prestige is near the national average.

Transport to Work

Car dependency is high at 88.3% driving to work, with only 6.0% using public transport and 0.9% walking or cycling, which is lower than the state capital norm. The suburb scores decile 8 on IRSD, meaning low disadvantage relative to the national distribution, and decile 9 on IER, indicating strong economic resources. Crime registers 92 total incidents in the dataset period, a rate of 27.5 per 1,000 residents, which is consistent with a low-crime area given national benchmarks. Only 5.1% of residents (167 people) need assistance with daily activities. The turnover rate is 11.4%, meaning 88.6% of residents remained in the same address over the census interval, one of the stronger stability signals compared to higher-turnover inner-city suburbs, suggesting residents generally remain by choice.

Established

Population growth is slow at 0.24% per year, adding roughly 12 persons annually. The 10-year change is 0.8%, placing Banksia Park in the slow-growth category compared to greenfield Adelaide fringe suburbs. Historical data shows population declining slightly from 5,068 in 2023 to 5,038 in 2025, with medium forecasts projecting a mild recovery to 5,175 by 2031. Net internal migration runs at negative 74 per year, offset only partially by overseas migration of positive 12. The gentrification stage is not gentrifying, consistent with a SEIFA score that is already well above the median nationally. Affordability improved from 39.0% in 2011 to 36.3% in 2021, moving in a favourable direction, while the aging trajectory, with the young share down 4.2 points over the decade, reinforces the plateau-growth outlook.

Banksia Park ranks at IRSD decile 8 nationally, indicating low disadvantage, and IER decile 9, reflecting strong household economic resources. Mortgage costs sit at 19.9% of income, well below the 30% stress threshold. The main trade-off is high car dependency at 88.3% and limited public transport at 6.0%, so a car is essential.

What is the median house price in Banksia Park?

The median house price reached $845,000 in Q1 2026, up 9.7% from $770,000 in Q1 2025. Monthly mortgage repayments average $1,550, giving a mortgage-to-income ratio of 19.9%. Weekly rent averages $350 for the small rental segment, which makes up only 10.5% of dwellings.

What schools are in Banksia Park?

No schools are recorded within the 1.99 km2 Banksia Park boundary in this dataset, so families rely on schools in neighbouring suburbs. The suburb's university qualification rate is 28.6%, which is 1.5 points below the national average, and the strong family-household profile means school access in adjacent areas is a key consideration.

Is Banksia Park safe?

Banksia Park recorded 92 total crime incidents, giving a rate of 27.5 per 1,000 residents. The IRSD decile 8 score places it in the low-disadvantage tier nationally, and only 5.1% of residents need daily assistance. The 88.6% residential stability rate, meaning most people stay year to year, also indicates a settled, low-disruption community.

Is Banksia Park good for property investment?

Weekly rent of $350 against an $845,000 median implies a gross yield around 2.2%, below the national average for detached houses. The 4.5% vacancy rate is moderate. Rent grew 14.6% over the period while real incomes grew only 0.2%, which gradually improves yield dynamics. Internal migration is negative 74 per year, so demand growth relies mainly on overseas arrivals.

How is Banksia Park's population changing?

Population is growing at 0.24% annually, adding about 12 persons per year. The 10-year change is 0.8%, well below the national average. Historical data shows a slight decline from 5,068 in 2023 to 5,038 in 2025, with medium forecasts projecting recovery to 5,175 by 2031. The suburb is aging, with the senior share up 3.5 points over the decade.

How much development is happening in Banksia Park?

There were 50 development applications lodged in the past 12 months. Recent examples include a subdivision creating 3 terrace-style allotments from 1, plus retaining wall works. The suburb is 99.7% separate houses already, so most new activity is infill subdivision or alterations rather than greenfield construction, consistent with an established, slow-growth area.

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.
