Onslow SF50-05 — AUSTopo 1:250,000 Topographic Map (2025)

Ashburton River country, Pilbara islands, and nationally important energy corridors—mapped with authority around Onslow and the coastal rangelands

Covering Onslow, the Ashburton River delta, the Mackerel Islands, and the surrounding western Pilbara coast and pastoral interior, this AUSTopo 1:250,000 sheet provides a clear, authoritative regional overview of country shaped by major seasonal waterways, tidal coastlines, working stations, and extensive resource infrastructure. From offshore islands and mangrove-fringed creeks to river floodplains, pastoral homesteads, industrial precincts, pipelines, and remote access roads, it is designed for professionals and experienced travellers who need dependable big-area context.

The sheet captures a strategically important coastal landscape where cyclones, flooding, river crossings, access conditions, and long travel distances all demand careful planning. Onslow, coastal facilities, pastoral leases, roads, tracks, waterways, contours, vegetation patterns, ports, airfields, and administrative boundaries are brought together in one coherent view—valuable for emergency coordination, energy and resource operations, environmental management, pastoral work, infrastructure planning, logistics, research, and serious remote-area 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 serious navigation.
