UWA is in Nedlands which is virtually opposite Alfred Cove on the Google Map. You would have to jump on to Canning Hwy and almost immediately turn onto the freeway, so make sure you are in the inner lane - close to the river. Then follow it around until you see the Stirling Hwy and Mounts Bay Rd exits - also on the river side, so stay in that lane. After getting off the freeway, head around on Stirling Hwy by the river until you come to UWA and then go to whichever part you need. It would probably take 10-15 mins on a good run, but peak times could make you very late!
