Trott Park
A median house price of $1,045,000 in a suburb where 97.5% of dwellings are separate houses places Trott Park well above most of metropolitan Adelaide, yet mortgage stress remains absent, with repayments taking only 20% of household income. Population density runs at 1,040 people per km2 across a 3.0 km2 footprint. The suburb holds IRSD decile 8 nationally, indicating low disadvantage, while the IER decile sits at 8, reflecting strong economic resources relative to most suburbs. Crime registers at 15.4 incidents per 1,000 residents, comfortably lower than typical metro benchmarks, and 86.1% of residents stayed put over the preceding year, well above average turnover rates.

The median house price reached $1,045,000 in the first quarter of 2026, up 32.3% from $790,000 a year earlier, a one-year gain that outpaces most SA markets. Stock is overwhelmingly detached houses at 97.5%, with 64% of homes having 3 bedrooms and 32.1% having 4 or more, so families seeking larger suburban homes will find supply concentrated here. Monthly mortgage repayments average $1,517, and the mortgage-to-income ratio holds at 20%, below the 30% stress threshold, meaning buyers are not overstretched relative to their incomes. Outright ownership at 32.8% is solid, while 53.9% carry a mortgage, indicating a predominantly owner-occupier market rather than an investment-heavy one. The semi-detached share is just 2.5%, so buyer competition for detached product is direct.

For Investors
Rental demand is thin here, with only 13.3% of households renting, compared to the national average above 30%. Weekly rent sits at $350, and against a $1,045,000 median the implied gross yield is below 1.8%, making yield-focused investment difficult to justify. The vacancy rate of 3.3% is moderate and not distressed, but rental supply is tight relative to the predominantly owner-occupier tenure split. Population grows at 0.59% annually, adding roughly 62 persons per year, supported by net overseas migration of 77 per year offsetting an internal outflow of 71. Development applications reached 26 in the past 12 months, mostly performance-assessed works on existing properties rather than new dwellings, consistent with a stable, established suburb. Capital growth is the stronger investment thesis here given the 32.3% price rise year-on-year.

Demographics
The median age of 39 is 1.0 year below the national figure, placing Trott Park in a slightly younger-than-average position despite an aging trajectory where the senior share rose 7.3 points over the decade. English (1,427 residents), Scottish (341) and Irish (291) ancestry dominate, making the suburb more Anglo-leaning than the national average. Overseas-born residents account for 22.0%, just 0.4 points above the national share, so international diversity is modest. University qualifications reach 29.4%, which is 0.7 points below the national figure, a small gap that aligns with the occupational profile of healthcare, construction and education workers. Average household size is 2.6, slightly above the national figure of 2.5, consistent with the high share of couples with children (1,086 families).

Tenure
The tenure profile leans heavily toward ownership: 32.8% own outright, 53.9% hold a mortgage, and just 13.3% rent, far below the national renter share. Separate houses account for 97.5% of stock, one of the more detached-dominant profiles in SA, which concentrates demand and limits substitution from apartments. Three-bedroom homes are the mode at 64%, with 4-plus bedroom dwellings at 32.1%, skewing toward family-sized properties. The median house price rose from $790,000 in Q1 2025 to $1,045,000 in Q1 2026, a 32.3% increase over one year. Despite that appreciation, mortgage-to-income at 20% and rent-to-income at 20% indicate that housing costs remain proportionate to local incomes at the 61.6th percentile of household income nationally.

Economy & Employment
Healthcare employs 22.6% of workers (239 residents), the single largest industry by a wide margin, followed by Construction at 12.4% and Education at 11.9%. These three sectors together account for nearly half the employed workforce, pointing toward essential-services stability rather than exposure to a single cyclical sector. Professionals are the top occupation group at 312 workers, followed by Clerical/Admin (256) and Community/Personal (231). The unemployment rate is 4.9%, slightly above but near the national baseline, and the full-time employment rate of 61.0% reflects a mix of full-time and part-time arrangements. SEIFA shows a split: the IRSD decile is 8 nationally, reflecting low disadvantage, while the IEO decile of 5 shows middling education and occupation levels, because the workforce leans toward hands-on healthcare and trades rather than high-credential professions.

Transport to Work
Car dependence is very high at 91.9% of commuters driving, compared to public transport use of just 2.6%, which reflects the suburban layout and limited rail or tram access typical of southern Adelaide suburbs. The crime rate of 15.4 incidents per 1,000 residents positions Trott Park below most metropolitan averages, consistent with the low-disadvantage IRSD decile 8 classification. The IRSAD decile 6 nationally indicates above-average relative advantage when both disadvantage and advantage factors are combined. Volunteering reaches 14.3% of residents, above average civic participation. No schools are recorded inside the suburb boundary in this dataset, so families draw on nearby institutions in adjacent suburbs. Need for daily assistance runs at 8.0%, with 244 residents requiring support, which is consistent with the aging demographic shift underway.

Population Forecast

EstablishedTrott Park grows slowly but steadily, with an annual rate of 0.59% adding around 62 persons per year. The 10-year population change reached 6.8%, classifying it as an established suburb with moderate organic growth rather than a development hotspot. The medium forecast projects the broader SA2 population rising from 10,468 in 2025 to 10,971 by 2031. Overseas migration is the primary growth driver at 77 net arrivals per year, offsetting internal outflow of 71. The suburb shows early gentrification signals with a score of 20, reflecting the 32.3% house price rise over one year and 4.0% real income growth, though affordability improved from 44.6% in 2011 to 42.4% in 2021, suggesting purchasing power is gradually catching up. The aging trajectory, with senior share up 7.3 points over the decade, will slowly shift household composition toward empty-nesters.

Is Trott Park good for property investment?
The 32.3% house price rise from $790,000 to $1,045,000 over one year makes a strong capital growth case. However, with only 13.3% of households renting and weekly rent at $350, gross rental yield is below 1.8% against the current median. Overseas migration of 77 per year provides steady demand support, but investors should focus on capital appreciation rather than yield.

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.
