Mount Gambier property market: the official numbers
The official read on Mount Gambier, SA: who lives there, what they pay in rent and repayments, and where the jobs are. Every figure below is ABS Census 2021 data, linked at the bottom so you can check it yourself.
The straight answer
Median rent in Mount Gambier was $220 a week at the 2021 Census — 41% below the national median. The typical repayment was $1,170 a month against $953 in rent — a middling gap, neither bargain nor squeeze.
What the census counted
The typical repayment ran at about 21% of the median household income. One caveat before you compare: everything here is August 2021. Repayments in particular have jumped since the 2022–24 rate rises. Treat these as a ranking tool, not a price tag.
Rent against the repayment
At the census, the typical monthly rent worked out to $953 against a typical mortgage repayment of $1,170:
What this gap does and doesn't tell you
The mortgage figure reflects loans and rates as at August 2021, before the 2022–24 rate rises — today's repayment on a new loan would be higher. The rent figure is what tenants were actually paying, not today's asking rents. The useful signal is the shape: where rent and repayments sit close together, buying has historically competed well with renting here; where repayments tower over rent, the market prices in growth.

The age mix
What the age mix means for housing
A heavy 25–44 band usually means family housing demand (and pressure on 3–4 bedroom stock); a heavy 65+ band signals downsizer and retiree demand (units, single-level living, proximity to health care). Mount Gambier's median age of 41 sits above the national median of 38.
Where the pay cheques come from
16.2% of Mount Gambier's 13,803 workers are in health care & social assistance. That's the engine under local housing demand — worth knowing how it's running before you buy.
