Boulder is the historic twin town of Kalgoorlie, sitting at the heart of WA's Goldfields region. The local economy revolves almost entirely around gold mining, delivering solid wages and affordable housing compared to Perth, but the remoteness is real. Crime and anti-social behaviour are recurring community concerns, and the town's social tensions have drawn national attention. For those willing to trade city comforts for outback character, Boulder offers a distinctive, working-class regional life.
Property prices sit at a median of $370k and rent of $620/week, which is 64% below the Perth metro median. At 6/100, the safety score sits 46 points below Perth's metro average of 52. School quality is around average, with 4 schools holding a combined 36/100 rating. At a median age of 35, households here bring in $1,968/week.
“The issues in Kalgoorlie are crime and anti-social behaviour. Lack of jobs is not an issue. We have too many jobs.”— 13 upvotes in community discussion
