Phillips played for the Oakleigh Chargers in the TAC Cup, appearing in 12 games and winning a premiership with them in the 2014 season. The next season he returned as an overage player, making the most of his final year in the development league. He kicked 23 goals in 16 games and selected as one of the best players half the time. In the Grand Final he tallied 18 disposals and kicked two goals to help them claim back-to-back premierships.[5] In 2015, Phillips spent time with Victorian Football League (VFL) club Port Melbourne, collecting 20 disposals and laying six tackles against Collingwood, the club which would draft him to the Australian Football League (AFL).[1]
Following the 2020 season, Phillips along with Jaidyn Stephenson and Adam Treloar were put up for trade by Collingwood due to salary cap issues. Phillips would eventually be traded to Hawthorn in exchange for Pick 65 in the 2020 AFL draft.[12]
Phillips played one pre-season game in the number 16 guernsey before the retirement of Tom Scully prior to the start of the 2021 AFL season allowed him to continue wearing his old number 21 for Hawthorn.[13]
^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.
