Great Northern Highway links Western Australia's capital city Perth with its northernmost port, Wyndham. With a length of almost 3,200 kilometres (2,000 mi), it is the longest highway in Australia, with the majority included as part of the Perth–Darwin National Highway. The highway is constructed as a sealed, predominantly two-lane single carriageway, but with some single lane bridges in the Kimberley. Great Northern Highway travels through remote areas of the state, and is the only sealed road link between the Northern Territory and northern Western Australia. Economically, it provides vital access through the Wheatbelt and Mid West to the resource rich regions of the Pilbara and Kimberley. In these areas, the key industries of mining, agriculture and pastoral stations, and tourism are all dependent on the highway.© Wikipedia
This is the main road from Wyndham to Port Hedland, which then heads inland through the Pilbara to Perth. We drove along the Great Northern Highway from Wyndham to Port Hedland - a very well maintained road with lots of great rest areas along the way that are equipped for overnight stays if required.
Western Australia really caters for those towing caravans or driving motorhomes because a number of these rest areas have toilets, BBQ facilities, shaded picnic tables, solar powered lights and dump points. We were very impressed with the facilities provided and would happily stay at some of these on our next trip.
