The traditional straight line course

 

For 2022, the 3.5km Swim Thru Perth has returned to a straight line course, beginning just north of the Narrows Bridge in Perth waters and ending at Matilda Bay.
The registration and briefing area is on the grassed area outside the UWA Sports Centre at Matilda Bay, Crawley. 
For the 1.6K Classic swim, Swimmers will enter the water at Matilda Bay, swim around the marked buoys and finish at Matilda Bay adjacent to the UWA Sports Centre.
