SA 5118 Census 2021 + Live DA Data

Gawler South

At a median age of 46, Gawler South residents are 6 years older than the national figure, and that demographic reality shapes everything from housing tenure to transport behaviour. Household income sits at the 27.3rd percentile nationally, making that price jump notable for a lower-to-middle income suburb. Three in four dwellings are separate houses, and nearly a third of residents own outright, indicating a long-settled owner base rather than a churn of new buyers.

Separate houses dominate at 74.7% of stock, with semi-detached dwellings at 23.7% and apartments at just 1.6%, so buyers face a traditional detached-house market with limited apartment alternatives. Three-bedroom dwellings make up 48.3% of housing, making them the most common configuration; 4-plus bedroom homes account for 23.4%. Monthly mortgage repayments average $1,300, producing a mortgage-to-income ratio of 24.3%, which stays below the 30% stress threshold despite household incomes at the 27.3rd percentile nationally. That manageable ratio is driven by historically modest price points before the recent surge.

For Investors

Gawler South offers a 31.2% renter share and weekly rent of $260, but the numbers warrant careful reading. The vacancy rate is 8.5%, elevated compared to a healthy market threshold of around 3%, signalling soft rental demand relative to available stock. On the positive side, 53 development applications were lodged in the past 12 months, indicating active construction interest. Turnover sits at 21.6%, with 78.4% of residents staying put, suggesting the owner-occupier base is stable. The 45.4% price jump in a single year raises questions about whether the current median is sustainable at this income level.

Demographics

University qualifications reach 22.8% of residents, which is 7.3 percentage points below the national average, consistent with a workforce concentrated in trades, community services and administration rather than professional sectors. Overseas-born residents account for 18.2% of the population, 3.4 points below national, and ancestry is predominantly Anglo-Celtic, with English the leading heritage (1,401 residents), followed by Scottish (266), Irish (261) and German (256). Average household size is 2.2, which is 0.3 below national, reflecting a profile of couples without children and single-person households typical of an aging community.

Tenure data reveals a suburb in a settled phase: 31.3% own outright, 37.6% carry a mortgage, and 31.2% rent, proportions that point to an established owner base alongside a meaningful rental segment.

The three-bedroom dwelling is the standard at 48.3%; 4-plus bedroom homes account for 23.4%, indicating families have historically chosen Gawler South for space. Monthly mortgage repayments average $1,300 and the mortgage-to-income ratio of 24.3% remains below the 30% stress threshold, though the recent price surge compresses future affordability.

Economy & Employment

Healthcare is the largest employing industry at 19.2% (146 workers), followed by Education at 15.0% (114) and Public Admin at 10.4% (79), making the public-sector services cluster the backbone of local employment. Construction accounts for 8.7% and Manufacturing 7.9%, pointing to a blue-collar dimension alongside the service economy. By occupation, Professionals (229) lead, but Community and Personal Service Workers (178), Clerical and Administrative workers (150) and Labourers (149) follow closely, a spread that reflects middle-skill rather than knowledge-economy employment. Unemployment sits at 6.5%, above the national average, and the participation rate of 55.0% is lower than typical, partly because the median age of 46 produces a larger share of residents outside the labour force (837 people).

Transport to Work

Car dependence is high by any standard, with 88.6% of residents driving to work, compared to a national average notably lower. Only 2.1% use public transport and 3.6% walk or cycle, reflecting Gawler South's position as a suburban commuter area where most destinations require a vehicle. No schools are recorded within the suburb boundary in this dataset, so families rely on facilities in surrounding Gawler townships. A crime rate of 60.0 incidents per 1,000 residents (157 total incidents) provides a baseline for safety assessment, though no breakdown by category is available. Volunteering at 16.4% indicates reasonable civic engagement, and 8.0% of residents (200 people) require daily assistance, a figure that aligns with the older median age of 46. Rent-to-income at 21.0% and mortgage-to-income at 24.3% both sit below stress thresholds.

Growth Outlook

However, the income base remains modest, with household income at the 27.3rd percentile nationally, which limits organic demand at the new price level. The suburb's identity signals point to a stable, aging resident base rather than a rapidly expanding population: 78.4% of residents stayed put over the reference period and the turnover rate of 21.6% is moderate. Development activity remains active with 53 applications in the past 12 months, including ancillary accommodation works, which may reflect interest in dual-occupancy and granny-flat construction consistent with housing affordability pressures across greater Adelaide.

Mobility data shows 78.4% of residents stayed over the reference period, with a turnover rate of 21.6%, consistent with a stable, aging community rather than a high-growth suburb.

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.
