Born in Drouin to Alfred and Colleen Ablett, Gary Ablett grew up in the Latrobe Valley in Victoria's Gippsland region alongside his four elder brothers and three sisters. Ablett displayed a love for sport at an early age, winning the state school high jump at 10 years of age. He was also awarded both club and competition best and fairest awards for Drouin at the under-11s, under-12s and under-14s levels. After citing waning interest in school, Ablett dropped out of high school at the age of 15 years to become a bricklayer's labourer.

Ablett combined strength, speed, and skill to produce many spectacular highlights and goal-kicking feats. A noted big game player, Ablett kicked 43 goals in 11 State appearances. More significantly, he booted 64 goals over the course of his 16 finals - an average of four goals a game. His haul of 27 goals in the 1989 finals series is a record that still stands. He was awarded the Norm Smith Medal for his performance in the 1989 Grand Final, where he was adjudged best player afield. In doing so, he became one of only four players (the others being Maurice Rioli -1982, Nathan Buckley -2002, and Chris Judd -2005) to win the medal playing for the losing side. In 1996, Ablett joined Gordon Coventry, Doug Wade, Jason Dunstall and Tony Lockett as the only players in league history to kick 1000 VFL/AFL goals.  Martin Flanagan's representation of Australian football pioneer Tom Wills in his 1996 novel The Call is modeled on Ablett. According to Flanagan, Wills and Ablett polarised opinion in similar ways, and displayed a lack of insight into their actions--they simply did what came naturally to them, "like a lot of artists". Ablett is the subject of the song "Kicking the Footy with God", released by The Bedroom Philosopher on his 2005 debut album In Bed with My Doona.  In 1996, Ablett was named in the AFL Team of the Century on the interchange bench, alongside Jack Dyer and Greg Williams. In 2001, Ablett was named in the Geelong Team of the Century, on a half forward flank. In 2005, after many years of controversy and debate (see below), he was inducted into the Australian Football Hall of Fame. The following year, he was honoured yet again when he was voted as the Greatest Geelong player of all-time ahead of Graham Farmer.  In 2006, Ablett was honoured with the naming of a terrace in his name within the newly renovated Skilled Stadium. Ablett once had a set of gates named in his honour, but he was upgraded to a terrace at the beginning of the 2006 AFL season.
