Harry Tobin played four games for Port Adelaide in 1915 and 1919 before moving residence and joining Norwood in 1920. He had shown promise playing for the Magpies in his last year at Alberton and brought that form to Norwood's pre-season internal trials.
Tobin made his senior debut for Norwood on a wing in the first round 1920 : Norwood 11.12 defeated Port Adelaide 7.10. However he had to wait until the crucial last minor round game of the season to play his second senior game - against West Torrens at Norwood.
The wingman was named in the best players and kept his spot for the finals. Tobin was an important player in Norwood's victory in the second semi-final against Port Adelaide and then played in the losing Grand Final versus North Adelaide.
In 1921, Tobin played in the drawn first semi-final against Port Adelaide. Norwood won the replay, but Tobin was a late out for that game.
He was then named 19th man for the next two finals, including the Grand Final loss to Port Adelaide. At the end of the season he played against Carlton on the Norwood Oval; Norwood 12.9 defeated Carlton 10.14.
Tobin's last league game was early in 1922. He was later named in the team that lost to West Torrens in the 1922 reserves Grand Final.
He played all of the 1923 season in the reserves.
