Mount Austin is Wagga Wagga's main residential suburb, sitting on the slopes above the Murrumbidgee River in the heart of the NSW Riverina. Wagga Wagga is a significant regional city — home to Charles Sturt University's campus and a major RAAF base — creating a diverse community of defence families, agricultural professionals, and students. The solar market in Wagga reflects this diversity: defence force families apply systematic research to solar decisions, agricultural families treat it as farm infrastructure investment, and university staff bring environmental motivation.
