  • Is it expensive to live in Mount Gambier?

    On the figures for Mount Gambier 5290, rents take a noticeable slice of a typical local household's income as recorded at the last Census. An average house rent of $470 a week is about 39.3% of the median weekly household income at the last Census, a sizeable share, while an average unit rent of $335 a week is about 28.0% of that income, a moderate share. Renting a unit therefore takes a smaller portion of a typical local household's income than renting a house.

    Looking at buying, the median house price of $600,000 is about 9.6 times a typical local annual household income at the last Census, and the median unit price of $431,500 is about 6.9 times that annual income. Both price multiples sit well above what a typical local household earned at the last Census, with houses more stretched against that income than units. Whether that feels expensive will depend on your own circumstances.

    Everyone's financial situation is different, so it's important to consider your own circumstances when deciding which suburb is right for you.
