Barwick began his early football career in the Tasmanian town of Queenstown and was noticed for the quality of his play in 1900 in a match against the visiting Fitzroy team from Victoria.[2] Within a few years he ventured to the mainland and in 1903 joined St Kilda.[3] He made his debut in the round six match versus Melbourne.[4]
A strongly built rover, he was good enough to represent the VFL against Western Australia in 1904[5] and topped St Kilda's goal-kicking in 1909 with 16 goals. Barwick also was club captain for both the 1905 and 1909 seasons. Although he would return to St Kilda briefly in 1913, Barwick finished his career at Brighton in the Victorian Football Association.
He was one of the earlier Tasmanian players to have made a mark in the Victorian Football League and in 2005 he was inducted into his state's Football Hall of Fame.[6]
