Port Noarlunga South
With 91.9% of dwellings being separate houses on a 3.2 km2 footprint, Port Noarlunga South is one of the more detached-dominant coastal suburbs south of Adelaide, yet its median house price of $940,000 places it well above most SA suburbs. The suburb recorded 11.4% price growth from $844,000 in early 2025 to $940,000 in early 2026, an unusual pace for a market of only 3,058 residents. Household income sits in the 48th percentile nationally, which means these buyers are stretching further than average relative to their earnings. A crime rate of 27.1 per 1,000 residents and a 5.5% disability assistance rate signal a generally stable, lower-risk community.

The 43.1% mortgage-holder share indicates a market with active recent buyers.
For Investors
Rental demand is moderate with 22.6% of properties rented and weekly rent at $350. The vacancy rate of 7.6% is elevated compared to national norms, suggesting some supply overhang. With 58 development applications lodged in the past 12 months, including land divisions and terrace construction, new supply continues entering the market. The 11.4% price gain over one year compared to a subdued rent level implies yield compression, with gross yield roughly 1.9%. The detached-house dominance (91.9%) and low-crime profile support owner-occupier demand, underpinning capital values more than rental returns.

Tenure
Tenure splits into mortgage holders (43.1%), outright owners (34.2%) and renters (22.6%). The 34.2% outright-owner share points to long-held, debt-free holdings. Stock is almost entirely separate houses at 91.9%, with apartments at only 6.6%, so density options are scarce. Three-bedroom dwellings dominate at 65.5% and 4-plus bedroom homes account for 27.6%. Mortgage-to-income and rent-to-income both sit at 22.9%, comfortably below the 30% stress threshold. Median price rose 11.4% from $844,000 to $940,000 in the year to early 2026, reaching a new peak.

Healthcare is the dominant industry at 21.9% of employed residents (226 workers), above the national share for any single sector, reflecting proximity to Southern Health Network facilities. Construction follows at 13.8% (142 workers) and Education at 11.3% (116 workers), with Public Admin at 9.0% and Professional/Tech at 6.8%. Professionals lead by occupation at 262, followed by Community/Personal service at 247 and Clerical/Admin at 193. The participation rate of 59.4% is below national averages because 814 residents are outside the labour force. Unemployment is 5.1%, higher than typical inner-metro Adelaide levels.

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.
