Dylan Timu scored a try, the only points for Perth Bayswater.
UWA are yet to find their premiershipwinning form of 2014 after suffering their third straight loss to Cottesloe 31-7, with Liam Husband and Levon Kvas-Rothwell combining for their only points.
Cottesloe were clinical in their victory on home soil, scoring a bonus point with their five tries. The Abel brothers Robbie and AJ scored three tries between them, with Western Force hooker Robbie crossing for a brace and Ivan Wright also scoring a double.
After a trailblazing start to the season, Joondalup has suffered their first defeat of their short Premier Grade history in a hard-fought 26-13 loss to Palmyra.
Palmyra claimed the RugbyWA Cup in the four-try bonus-point victory and will defend it against UWA next round.
Nedlands sit just outside the top four following their 41-5 defeat of Wanneroo.
