General Information:
National Route 1 is a mostly somewhat coastal route in Western Australia. In some cases it travels quite close to the coast and the Indian and Southern Oceans and at other times it is further inland, but still generally following the coastline.
The quality of the route varies from rural 2 lane highway to multi-lane suburban arterial road and also freeway standard.
History:
- Forrest Highway:
- 30 June 1995: Work started on the extension of dual carriageway from Springhill Road near Binningup to the Myalup turnoff. 2

- 2000: The dual carriageway of Old Coast Road was extended up to Lake Clifton. 5
- September 2009: Completion of construction works for intersection with Forrest Hwy (SR2) and Peppermint Grove Rd at Lake Clifton.
- June 2014: Forrest Highway name extended and as a result of a Landgate decision, now runs from the end of Kwinana Freeway near Mandurah to the Eelup Roundabout in Bunbury, renaming Australind Bypass and one section of Old Coast Road. The decision to rename 57 km of the road was made to clear up confusion caused by the road's three names. 6
