Port Augusta, located at the crossroads of Australia’s north–south and east–west highways, is often called the “Crossroads of Australia.” This historic South Australian town sits at the tip of the Spencer Gulf and serves as a gateway to the Flinders Ranges and the vast Outback beyond. Once a key port and railway hub, today it’s a place to explore rugged landscapes, Aboriginal culture, and desert botanic gardens — all under the gaze of the ever-changing Southern sky.
