Burb Score · burbscore.com/suburb/karnup
Karnup is a quiet, car-dependent suburb on Perth's southern fringe, wedged between Baldivis and Wellard along the Kwinana Freeway corridor. It appeals to buyers seeking space and affordability in a growing area, though infrastructure lags behind population growth: a long-awaited train station lost funding, freeway congestion worsens, and power reliability has been an ongoing irritant. Bushfire awareness is essential for residents near the surrounding bushland. Property prices sit at a median of $786k and rent of $650/week, which is 23% below the Perth metro median.
Expect a 46-minute drive to the CBD, and most residents drive (66%). Crime levels are moderate, and the 63/100 safety score is 11 points above the metro mean of 52.
