He did not play between 1940 and 1944 due to his war service in the Royal Australian Navy as a lieutenant.

In 1947, Blackman crossed to Victorian Football Association club Preston as captain-coach without a clearance.

[4] He played there under throw-pass rules for three years, and he won the J. J. Liston Trophy in 1949.
