Great Northern Highway begins at Morrison Road, Midland, in Perth's north-eastern suburbs, signed as National Route 1.
Though it originally commenced at Great Eastern Highway, that section is no longer contiguous, and is now named Old Great Northern Highway.
The highway heads north through Middle Swan, intersecting the start of Toodyay Road after 1.3 kilometres (0.8 mi), and then the meeting point of Reid and Roe Highways after another 1.4 kilometres (0.9 mi).
Those highways come together from Perth's ring road, signed as State Route 3, and north of this intersection Great Northern Highway is concurrently allocated National Highway 95 and National Route 1.
It continues north through the Swan Valley for 9.5 kilometres (6 mi), passing many wineries, restaurants, and other tourist attractions.
The highway crosses the Swan River and intersects West Swan Road, before turning north-east to travel around the residential part of Upper Swan.
Great Northern Highway continues north for thirteen kilometres (8 mi) beyond West Swan Road, past larger agricultural properties, to reach Bullsbrook, the last urban area within the Perth Metropolitan Region.
After 11.5 kilometres (7 mi) beyond Bullsbrook, the highway reaches the edge of the Perth metropolitan area at the City of Swan–Shire of Chittering boundary, where it passes into the Wheatbelt.
