The topography of New South Wales is dominated by the Great Dividing Range. The state's highest point is Mount Kosciuszko, located in the Snowy Mountains, standing at 2,228 meters (7,310 feet) above sea level. This alpine region is one of the few places in Australia to experience regular seasonal snowfall.
The state's lowest point is sea level along its 2,137 km (1,328 mi) Pacific coastline.
Beyond the mountains, the topography flattens out significantly. The western two-thirds of the state consist largely of plateaus, plains, and subtle undulations, forming part of the Great Artesian Basin and the Murray-Darling Basin. Coastal areas are marked by deep natural harbors (like Sydney Harbor and Port Stephens) and flood plains fed by short, fast-flowing coastal rivers.
