Throssell SG51-15 — AUSTopo 1:250,000 Topographic Map (2025)

Lake Throssell, Great Central Road country, and vast desert horizons—mapped across Western Australia’s remote interior

Covering Lake Throssell and the surrounding Great Victoria Desert country northeast of Laverton, this AUSTopo 1:250,000 sheet delivers an authoritative regional view of a deeply remote and culturally significant landscape. The ephemeral salt-lake system sits among red sand ridges, spinifex and shrub plains, stony ground, rocky rises, claypans, and scarce natural water sources.

The Great Central Road provides the principal overland corridor through the region, supported by a sparse network of desert tracks and access routes. From Lake Throssell’s wetland system to surrounding terrain, vegetation, drainage features, and isolated infrastructure, the map provides essential big-area context for land management, environmental research, emergency coordination, professional fieldwork, and properly prepared desert travel.

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.
