Career
Aish and long time Norwood teammate Garry McIntosh continually resisted many big-money offers to move to Melbourne to play in the Victorian Football League (VFL) and remained loyal to Norwood and South Australian football. This was helped also by the SANFL"s controversial player retention scheme where the league paid to keep as many South Australian players in the local league as possible rather than see them cross the border to play for VFL clubs. Aish was the second son of former Norwood captain and coach Peter Aish.
Aish represented South Australia 15 times at interstate football, captaining the side in 1986 and 1989 as well as earning All-Australian selection in 1983 and 1986.
