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. He was a wingman but towards the end of his career was used as a ruckman. In 1926 Mason tied with Harold Matthews for St Kilda's Best Player award  and represented Victoria at interstate football for the first of six times. After leaving St Kilda he became the coach of Camberwell Football Club in the Victorian Football Association (VFA), and he was later named coach of the Camberwell Team of the Century. He also played for Kyneton.
