Ajana SG50-13 — AUSTopo 1:250,000 Topographic Map (2025)

Kalbarri’s dramatic gorge country, the lower Murchison River, and the remote coastal landscapes around Ajana—mapped with authority across Western Australia’s Mid West

Covering Kalbarri, Ajana, Galena, the lower Murchison River, and the surrounding coastal and inland districts, this AUSTopo 1:250,000 sheet provides a clear, authoritative regional overview of country shaped by an immense river gorge, rugged sandstone plateaus, coastal cliffs, working properties, and long regional roads. From the mouth of the Murchison River and Kalbarri National Park to historic localities, pastoral country, the northern edge of the farming belt, and remote access tracks, it is designed for professionals, land managers, residents, and experienced travellers who need dependable big-area context.

The sheet captures a landscape where steep relief, river crossings, bushfire risk, seasonal flooding, and road access can all matter. Towns, homesteads, highways, park roads, tracks, waterways, contours, vegetation patterns, conservation reserves, and administrative boundaries are brought together in one coherent view—valuable for emergency coordination, park management, environmental work, tourism operations, pastoral and agricultural planning, infrastructure maintenance, logistics, research, and regional navigation.

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 understanding how the Murchison River, national park, coastal settlements, and inland road network fit together.
