West Adelaide not only became SANFL premiers for the first time defeating Norwood in the Grand Final at the Adelaide Oval but they also became Champions of Australia when they defeated powerful Victorian Football League team Carlton by five goals at the Adelaide Oval. James "Sorry" Tierney was the club's first ever winner of the Magarey Medal in 1908.
