Educated at Grovedale College, Whyte played both Australian rules football and basketball during his junior career, spending three years as part of the Geelong Supercats program.[2] In 2021, he would finish as runner-up in the Geelong Falcons best-and-fairest, behind fellow future Geelong draftee Mitch Knevitt.[2] Before being drafted by Geelong, Whyte was a Collingwood supporter.[2]
Described as a swift midfielder with a long left foot kick,[3] Whyte was identified by AFL recruiters ahead of the 2021 AFL draft,[4] eventually being selected by Geelong with pick 64.[5]
AFL
A groin injury kept Whyte out of the Geelong team during much of the 2022 AFL season,[6] restricted to just the first four games playing with Geelong's VFL team. After impressing during preseason training ahead of the 2023 AFL season,[6] Whyte made his AFL debut for Geelong, coming off the interchange bench as the tactical sub for the last quarter in Geelong's round 2 loss against Carlton.
Whyte was delisted by Geelong at the conclusion of the 2023 season.[7]
VFL
Whyte became a VFL premiership player in 2024, playing for Werribee in a six-point grand final victory over Southport.[8][9]
