Klemzig
A median house price of $1,215,000 in a suburb where household income sits at only the 46.5th percentile nationally is the defining tension in Klemzig. Prices jumped 32.3% in a single year, from $918,500 in 1Q 2025, far outpacing local earning power. The population of 6,713 is young for an inner-ring suburb at a median age of 36, which is 4.0 years below national, and unusually international, with 42.3% born overseas, 20.7 points above national. University qualifications reach 51.6%, running 21.5 points above the national figure, which helps explain why a renter-heavy area at 42.3% still draws premium prices just 6 km from the Adelaide CBD.

The $1,215,000 median reflects a 32.3% one-year surge from $918,500, a pace that has run well ahead of the 46.5th-percentile local incomes, so buyers are increasingly stretched relative to what residents actually earn. Stock favours families: 68.3% are separate houses against 17.5% apartments, and three-bedroom homes dominate at 53.7%, with two-bedroom at 27.7% and four-plus at just 16.0%. Despite the steep price, monthly mortgage repayments average $1,684, giving a mortgage-to-income ratio of 26.1%, comfortably below the 30% stress threshold, because many recorded mortgages predate the recent price run. The detached-house skew means first-home buyers compete for a relatively scarce supply of smaller dwellings.

The detached-house skew means first-home buyers compete for a relatively scarce supply of smaller dwellings.
For Investors
Weekly rent of $300 against a $1,215,000 median implies a gross yield near 1.3%, very low, so the investment case here rests on capital growth rather than income. That growth has been strong: prices rose 32.3% in the year to 1Q 2026. Renters make up 42.3% of households, well above typical owner-occupier suburbs, giving a deep tenant pool, and the vacancy rate of 6.0% sits higher than a tight market would show, hinting at adequate supply. Development is modest at 41 applications over 12 months, mostly sheds, pools and retaining-wall repairs rather than new dwellings, so supply additions are limited. Rent-to-income at 20.2% keeps tenants well below stress, which supports rent stability more than rapid escalation.

Demographics
Klemzig skews young and international. The median age of 36 is 4.0 years below national, and 42.3% of residents were born overseas, 20.7 points above the national figure. University qualifications reach 51.6%, running 21.5 points above national, a highly educated base for a mid-income area. Ancestry leads with English (1,575) and Italian (825), but Indian (720) and Chinese (637) communities are substantial, and the top non-English languages are Mandarin (186 speakers), Gujarati (179) and Punjabi (166). Hinduism is the clear second religion at 737 residents behind Christianity at 2,660. Average household size is 2.3, which is 0.2 below national, and couples without children make up 28.1% of families, consistent with the younger, migration-driven profile.

Tenure
Tenure is renter-led: 42.3% rent, 30.8% carry a mortgage and 26.9% own outright, a younger and less settled mix than ownership-dominated suburbs. The stock is 68.3% separate houses with apartments at 17.5% and semi-detached at 14.2%, and three-bedroom dwellings account for 53.7% against 27.7% two-bedroom and 16.0% four-plus. The median house price climbed from $918,500 in 1Q 2025 to $1,215,000 in 1Q 2026, a 32.3% one-year jump that has lifted the price-to-income gap sharply given household income at the 46.5th percentile. Mortgage-to-income sits at 26.1% and rent-to-income at 20.2%, both below stress thresholds, because the recorded loans largely predate the latest price surge rather than reflecting today's entry cost.

Economy & Employment
The workforce leans heavily on Healthcare, which alone employs 23.2% of workers (592 people), followed by Education at 10.3% (262) and Professional/Tech at 9.7% (248), with Public Admin at 7.7% and Retail at 6.4%. By occupation, Professionals lead at 941, ahead of Community and Personal Service workers (473), Clerical and Admin (383) and Managers (364), a mix that fits the 51.6% university qualification rate, 21.5 points above national. Full-time employment runs at 60.0% and unemployment at 6.0%, with participation at 59.7%, held down partly by 1,837 residents not in the labour force. The healthcare concentration gives the local economy defensive stability, because demand for care services is less cyclical than retail or construction.

Transport to Work
Klemzig is car-oriented but not isolated: 78.7% drive to work while 12.9% use public transport and 2.8% walk or cycle, helped by its position about 6 km from the CBD on the O-Bahn corridor at a density of 2,674 residents per km2. Crime runs at 51.8 incidents per 1,000 residents (348 total), a moderate level for an inner-ring suburb. No schools are recorded inside the 2.51 km2 boundary in this dataset, so families rely on institutions nearby, though the highly educated base, with university qualifications 21.5 points above national, points to strong demand for them. Volunteering at 15.0% and 7.7% of residents needing daily assistance round out a settled, family-heavy community profile.

Is Klemzig good for property investment?

How is Klemzig's population changing?
Klemzig's 6,713 residents skew young, with a median age of 36, which is 4.0 years below national. The suburb is migration-driven, with 42.3% born overseas, 20.7 points above national, and a turnover rate of 26.6%, so household formation by newer arrivals is the main demographic force.

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.
