Brompton
Over half of Brompton's housing stock is semi-detached, a figure that sits well above the Adelaide average, yet the suburb's median house price of $1,160,000 has climbed 9.4% in a single year. The population of 3,729 is highly educated, with 54.8% holding university qualifications, which is 24.7 percentage points above the national figure. Despite those credentials, 53.8% of residents rent rather than own, making this one of South Australia's renter-majority inner suburbs. The SEIFA IEO decile of 8 confirms strong educational and occupational advantage, while the IRSD decile of 5 reflects a mixed socioeconomic picture across the suburb's 1.13 square kilometres.

The median house price of $1,160,000 in Q1 2026 represents a 9.4% gain from $1,060,000 in Q1 2025, a sharp single-year move. Stock composition favours semi-detached dwellings at 54.1% with separate houses at 43.1%, so buyers competing for a detached property face limited options. Three-bedroom dwellings dominate at 50.5%, followed by two-bedroom at 35.4%, with four-plus bedrooms making up just 8.5%. Monthly mortgage repayments average $1,733, and with the mortgage-to-income ratio at 22.1%, Brompton sits below the 30% stress threshold, offering more serviceability headroom than many comparable inner-Adelaide suburbs. Outright owners account for just 16.9% of households, below what you would expect in a suburb at this price point, because much of the stock has changed hands recently and carries debt.

For Investors
With 53.8% of residents renting, Brompton offers one of the stronger tenant pools among inner SA suburbs. Weekly rent averages $380, and the vacancy rate of 8.0% is elevated, signalling that supply is outpacing demand in the current leasing market and warranting caution on short hold periods. Overseas migration is the primary population driver, with a net inflow of 372 people per year, which supports rental demand over the medium term even as internal migration runs at negative 132 annually. Development activity logged 33 applications in the past 12 months, modest for a suburb this size, suggesting limited new supply is entering the market. The 9.4% price gain from Q1 2025 to Q1 2026 points to capital growth momentum, though the high vacancy rate means investors should stress-test yield assumptions carefully.

Demographics
The median age of 36 is 4 years below the national figure, reflecting a workforce-age concentration that partly explains the high rental share. Overseas-born residents account for 34.9% of the population, which is 13.3 percentage points above the national average, with English (1,187), Irish (340) and German (275) the leading ancestries. Non-English languages are modest in volume: Greek is the most spoken at 88 residents, followed by Mandarin at 44. University qualifications reach 54.8%, running 24.7 points above national and placing Brompton among the more educated inner suburbs in South Australia. Average household size of 2.1 is 0.4 below national, consistent with the high proportion of couples without children at 39.5% of families. The volunteering rate of 15.2% reflects moderate civic engagement.

Tenure
Tenure in Brompton is unusual: 53.8% rent, 29.2% carry a mortgage, and only 16.9% own outright, a pattern more typical of student or transient corridors than a suburb with a $1,160,000 median. Compared to the SA average, renters are heavily over-represented, which compresses outright-owner wealth despite rising prices. Semi-detached dwellings account for 54.1% of stock and separate houses 43.1%, with apartments a marginal 2.5%. Three-bedroom dwellings dominate at 50.5% and two-bedroom at 35.4%. The price moved from $1,060,000 to $1,160,000 in one year, a CAGR of 9.4%, on just two quarters of data. Rent-to-income sits at 21.0% and mortgage-to-income at 22.1%, both below stress thresholds, suggesting current occupiers are not under financial pressure despite the price trajectory.

Transport to Work
Active travel is relatively high: 9.0% of Brompton residents walked or cycled to work, above the national average, and 8.1% used public transport. Car dependency at 76.4% is still the norm but lower than many outer suburbs. The crime rate of 137 incidents per 1,000 residents is elevated compared to the SA average, and the identity signal confirms high-crime-rate status, so buyers should factor in security considerations. The IRSAD decile of 6 and IRSD decile of 5 indicate a mid-range socioeconomic position nationally. No schools are recorded within the 1.13 square kilometre suburb boundary, so families depend on institutions in adjacent areas such as Bowden and Hindmarsh. Rent-to-income at 21.0% keeps tenants comfortable, and the housing stress flags are clear on both mortgage and rent measures.

Population Forecast

(+226 people/yr)
EstablishedBrompton's population expanded 14.7% over the past decade, faster than many established inner suburbs, driven primarily by overseas migration at a net 372 arrivals per year. Internal migration runs negative at 132 per year, meaning longer-term residents are leaving as newer arrivals fill the gap. Annual growth currently runs at 1.1%, adding approximately 226 people per year. The gentrification score of 54 with an active stage signals ongoing transition: the young adult share has declined 2.1 points while the working-age and senior shares both increased, and affordability improved from 44.1% in 2011 to 41.6% in 2021. Medium-series forecasts project the broader SA2 population rising from around 20,466 to 21,780 by 2031, reflecting sustained but measured growth driven by overseas arrivals rather than natural increase.

Is Brompton good for property investment?

However, the vacancy rate of 8.0% is elevated, and gross yields against this median are modest. Net overseas migration of 372 per year supports ongoing rental demand, but investors should stress-test vacancy assumptions given current supply conditions.

Recent examples include a change of land use to food production, a rear verandah addition and a proposed carport with front masonry fence. Activity is moderate for a 1.13 square kilometre suburb, suggesting incremental improvements to existing dwellings rather than significant new supply entering the market.
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.
