Mount Gambier sits in southern or western Australia, where a Mediterranean-to-arid climate produces mild, wetter winters and long, dry summers, with the region’s biggest flood risk coming from occasional intense summer thunderstorms or ex-tropical cyclone remnants.
In South Australia’s southeast, the city sits atop a limestone region riddled with sinkholes, which affects how rainfall drains compared to typical surface-water cities. Because much of the region normally receives modest rainfall, a rare intense storm can overwhelm drainage systems built for a drier norm, and radar helps track these less-frequent but potentially serious events.
