Robert SG51-11 — AUSTopo 1:250,000 Topographic Map (2025)

Little Sandy Desert wilderness, the Lake Wells system, and culturally significant water places—mapped across remote central Western Australia

Covering the Robert map area and adjoining Lake Wells country, this AUSTopo 1:250,000 sheet delivers an authoritative regional view of the Little Sandy Desert. It captures a vast and sparsely settled landscape of red sand ridges, spinifex plains, low rocky features, salt lakes, claypans, ancient drainage systems, and extremely limited surface water.

Named places such as Empress Spring and Pikalu Rockholes reflect the enduring importance of reliable water across this culturally significant desert Country. With the Lake Wells system, natural water features, vegetation patterns, remote tracks, and isolated localities brought together in one coherent view, the map provides valuable context for land management, geological and environmental research, heritage work, emergency planning, and specialist field operations.

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.
