Derby SE51-07 — AUSTopo 1:250,000 Topographic Map (2025)

King Sound tides, Fitzroy floodplains, and the western gateway to the Gibb River Road—mapped across the West Kimberley coast and interior

Covering Derby, Mowanjum, King Sound, the lower Fitzroy estuarine country, and the western beginning of the Gibb River Road, this AUSTopo 1:250,000 sheet provides an authoritative regional view of one of the Kimberley’s most important coastal gateways. Tidal creeks, mangroves, mudflats, river channels, floodplains, pastoral country, and remote road corridors meet across a landscape shaped by immense seasonal and tidal change.

The map places Derby and its transport links within their wider terrain, showing the relationship between the town, port and jetty precinct, airport, Great Northern Highway, Gibb River Road, surrounding communities, waterways, and station tracks. It is particularly useful for regional planning, infrastructure and logistics, flood and emergency coordination, land management, environmental research, and travellers seeking topographic context for the western approach to the Kimberley interior.

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, catchment and coastal management, emergency coordination, and serious remote-area navigation.
