Adored by young fans for his handsome appearance, Mainwaring was one of the most popular footballers of his era.

Whilst he never won the Club Champion award at the Eagles, he finished in the top 10 eight times, including placing third in both his debut and second years in the VFL and second in 1989, 1992 and 1996.

In 1998, while he was attempting to regain form, Mainwaring spent most of the season playing for the Sharks, before making his return to the West Coast side late that year.

After another season in which he was in and out of the Eagles' side (and playing for East Fremantle), Mainwaring retired from AFL football.

The club retired the number for the following three seasons, until it was revived by Eagles' draft pick Andrew Gaff in 2011.

Mainwaring died in the early hours of 1 October 2007 after being rushed to Sir Charles Gairdner Hospital.

[6] Police and ambulance had been called to his address earlier that night after a complaint about a man yelling in the street.

[4] Mainwaring's memorial service was held on 8 October 2007 at Christ Church Grammar School, Claremont.
