The Bureau of Meteorology (BoM) confirmed the wild weather that hit Hilton, O'Connor and Claremont early on Monday was a tornado.
As well as downing power lines, it tore roofs off homes, smashed trees and sent a dinghy flying into the front yard of a house.
A BoM spokeswoman said a wind engineer had inspected damage in Hilton and concluded the tornado that hit the suburb packed wind speeds well exceeding 125km/h.
