Rason SH51-03 — AUSTopo 1:250,000 Topographic Map (2025)

Lake Rason, protected desert wilderness, and remote expedition country—mapped across the heart of the Great Victoria Desert

Covering Lake Rason and the surrounding Great Victoria Desert interior, this AUSTopo 1:250,000 sheet presents an authoritative regional view of one of Western Australia’s most isolated landscapes. The intermittent saline lake forms a striking focal point within a broader terrain of red sand ridges, spinifex and mallee plains, stony ground, claypans, rocky ranges, and scarce natural water sources.

Much of the area is associated with the Plumridge Lakes Nature Reserve, an important protected landscape reached by lightly formed desert routes such as Rason Lake Road. From the Lake Rason system and Doctor Hicks Range to remote tracks, rockholes, drainage features, and vegetation patterns, the map provides essential big-area context for conservation operations, field research, emergency planning, and properly equipped desert expeditions.

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.
