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 signed a one-year contract for the 1984 season with Geelong, and he began his first season under the guidance of Tom Hafey. He debuted for the Cats in Round 7 and after just nine games on the wing, Ablett was selected to his first State of Origin game for Victoria. Ablett earned best-on-ground honours after kicking 8 goals from the half-forward flank. He played 15 games and kicked 33 goals in the 1984 season, and was awarded the Carji Greeves Medal as the Geelong Football Club's "best and fairest" player of the year. Following his first season with Geelong, Ablett signed a new three-year contract with the club. Playing mostly on the half forward flank, Ablett won the club's goalkicking award for the following two seasons with 82 and 65 goals respectively. Although Ablett had developed a reputation for his laconic, lazy attitude to training under coach John Devine, this did not prevent him from earning top three placings in the best and fairest awards from 1985-87. With his contract expiring at the conclusion of the 1987 season, Ablett shocked the VFL by signing a new five-year contract with his former club, Hawthorn. After a "cooling-off" period, however, Ablett opted to remain with Geelong by agreeing to a lucrative five-year contract that tied him to the club for the long-term. Ablett began the 1988 season with 59 goals after just 11 games, placing him second on the goalkicking list behind Hawthorn's Jason Dunstall. In these games, he kicked 10 goals against Richmond in the Anzac Day game, and 11 against Brisbane--one shy of breaking the ground record of 12 goals at Carrara. Although he missed out on State honours and failed to place within the top three in the club best and fairest award, Ablett finished with 82 goals during the season for the second time in his career.
