Prince Regent SD51-16 — AUSTopo 1:250,000 Topographic Map (2025)

A legendary Kimberley river, terraced waterfalls, and an intricate wilderness coast—mapped with authority

Covering the Prince Regent River and adjoining north-west Kimberley coast, this AUSTopo 1:250,000 sheet presents a clear, authoritative regional view of one of Australia’s most remote and spectacular wilderness landscapes. Towering sandstone country, deeply incised waterways, tidal basins, islands, inlets, waterfalls, and rugged coastal ranges combine across an area reached principally by boat or air.

The sheet includes Prince Regent National Park, the Prince Regent River, Maamboolbadda/King Cascade, St George Basin, Careening Bay, Hanover Bay, Mount Trafalgar, and Mount Waterloo. It also extends across the Glenelg, Hunter, Roe, and Sale river systems, Prince Frederick Harbour, Port George IV, Camden Harbour, and numerous islands and coastal passages—making it an exceptional reference for conservation work, expedition cruising, scientific research, heritage study, and remote-area coordination.

At 1:250,000 scale (1 cm = 2.5 km), this is the largest scale at which published topographic maps cover the entire Australian continent—ideal for regional planning, land management, emergency coordination, and serious remote-area navigation.
