In 1948, Colac Diggers Football Club (Made up of returned servicemen) disbanded and a number of the players transferred to the Imperials.

In 1949 a large number of Imperials players moved across to the newly formed Colac Tigers, they in turn took over the Western Oval, thus Imperials moved back to the Colac Showgrounds.

In 1950, after being successful in the CDFL, the club moved to the Polwarth Football Association.

Participating teams were: Apollo Bay, Lorne, Winchelsea, Deans Marsh, Birregurra, Beeac, Coragulac Rovers and Forrest.

With 12 senior flags to their credit since 1945, the Cats have been the Colac and District Football League’s second most successful post-war club, behind Alvie.
