Will played his junior football at local club PHOS Camden. He was part of the SANFL junior development programs at Glenelg before transferring to West Adelaide, (where his grandfather had played) for better opportunities.[2] In 2019, he played for South Australia in the under-18 national championships as well as playing three reserves games.[3] He went to school at Sacred Heart College.
AFL career
Day's AFL career was initially hampered by the COVID-19 pandemic. As a young player coming into the system, Day would normally start by playing with the Hawthorn affiliate, Box Hill Hawks, but because that competition had been suspended for the year he had to show his mettle with scratch matches against other AFL clubs.
Day made his AFL debut in Round 6, 2020, against Collingwood at Giants Stadium.[4]
Day received a Rising Star nomination after round 16, 2020.[5]
He had an injury-affected season in 2021. He fractured an ankle against Richmond in Round 3. He recovered in time to play in round 13 that year and played another three games for the season before having complications from his earlier injury.[6]
Day re-signed with Hawthorn until 2027 in April 2023.[7]
^The 2020 season was played with 17 home-and-away matches per team (down from 22) and 16-minute quarters with time on (down from 20-minute quarters with time on) due to the impact of the COVID-19 pandemic.
