Pacific Highway (Australia)
The Pacific Highway is the coastal highway that goes between Sydney and Brisbane, and is 1,025 km (637 mi) long. It's a pretty drive, with exits to the coastal towns along the way. Slower than the inland route.
Between Sydney and Newcastle, and between Ballina and Brisbane, Queensland, this highway becomes the Pacific Motorway (see for more info]). Everywhere else in between Newcastle and Ballina is the Pacific Highway and it is possible to hitch directly on the highway in many places where there is room for cars to stop.
