Career
After growing up in Richmond, Turnbull commenced his senior football career with Street Kilda in 1914, making eight appearances in his first season. He was reported as having enlisted in late 1915 although there are no official service records under his name in the official archives. In 1918, Turnbull returned to senior football, playing the first eight rounds before being excluded from the team by the Street Kilda committee “in the best interests of the team, owing to his play”.
He was reinstated late in the 1920 season and played two more games for Street Kilda before moving to Richmond for the 1921 VFL season.
After football Turnbull became a successful horse trainer, later moving to Sydney.
