The 1927 WAFL season was the 43rd season of the West Australian Football League. It saw the last premiership of the East Perth dynasty dating back to the end of World War I, as mastermind coach Phil Matson was to be killed in a truck crash the following year[1] and the Royals were to fall to a clear last in 1929 as most of their champions retired. Despite opening their permanent home ground at Claremont Oval, newcomers Claremont-Cottesloe showed little improvement on their debut season and again won only a single game. The most notable change in fortunes was from South Fremantle, who had their first season with more wins than losses since their last premiership in 1917, and extended Matson's Royals in the grand final.
VFL champions became the second Victoria club to tour Perth after Fitzroy in 1922,[2] and although an interstate carnival meant they were without several top players, the Magpies performed well enough to win one of their two matches against a representative team from those WAFL players not at the carnival.
