Originally from Tasmania where he had been a premiership player with North Hobart Football Club, Mason debuted for St Kilda in the 1922 VFL season.
In 1926 Mason tied with Harold Matthews for St Kilda's Best Player award[2] and represented Victoria at interstate football for the first of six times.
His arrival sparked the emergence of the Tricolours as a VFA force for the first time, but a runner-up spot to Yarraville in 1935 was the closest they could get to a flag.
Mason was appointed as coach of the Kyneton Football Club in 1934,[3] but resigned after eight games.
[7] Mason later served in the Royal Australian Navy during World War II.
