The West Australian Current (or the Western Australian Current) is a cool surface current of the Southern Ocean and Southern Indian Ocean.
Track
It starts as the Southern Indian Ocean Current, a part of the larger Antarctic Circumpolar Current (also known as the West Wind Drift{{Citation | author1=Sanmartín, Isabel | author2=Wanntorp, Livia | author3=Winkworth, Richard C | title=West Wind Drift revisited: testing for directional dispersal in the Southern Hemisphere using event-based tree fitting | date=2007 | publisher=Blackwell Publishing Ltd | url=http://trove.nla.gov.au/work/16964851 | access-date=8 October 2014 }}). As the current approaches Western Australia, it turns north, parallel to the western coast of Australia, and becomes the West Australian Current.
Effects
The current is mainly seasonal, being weaker in winter and stronger in summer, and is affected by the winds in that area.{{Citation | author1=Australia.

In addition to the West Australian Current flowing on the Western Australian Coast, the Leeuwin Current{{Citation | author1=Holloway, Peter E | title=Leeuwin Current observations on the Australian North West Shelf, May-June 1993 | journal=Deep-Sea Research Part I: Oceanographic Research Papers | date=1995-03-01 | volume=42 | issue=3 |page=285 | issn=0967-0637 | doi=10.1016/0967-0637(95)00004-p}} and Southern Australian Countercurrent, also flow along this coast, with the former flowing in the opposite direction. These three currents together contribute greatly to the rainfall and climate in the southwest region of Western Australia.http://www.csiro.au/Outcomes/Climate/Understanding/AustralasianOceanCurrents.aspx Australian Ocean Currents - CSIRO overviewhttp://www.bom.gov.au/oceanography/forecasts/idyoc10.shtml?region=10&forecast=1 BOM indicator of current temperatures
