AFL Rising Star winner Callum Mills has committed to Sydney for the long term, inking a new five-year contract extension.

The QBE Sydney Swans Academy product, who had two years to run on his existing contract, will now be a Swan until at least the end of 2023.

Recruited with pick three in the 2015 AFL Draft, Mills made his debut in Round 1 the following year and instantly impressed.

Playing across halfback, Mills showed poise and maturity beyond his years, averaging 19 disposals and five marks from 22 games.

After a strong pre-season, the Swans’ No. 14 will be eyeing off an even bigger campaign in 2017.

Sydney’s Head of Football Tom Harley says he’s rapt that Mills has committed to the red and white.

“We are excited to have Callum commit to the club long term,” Harley said.

“Although Callum's career is only 12 months old, we are extremely confident of the impact he will make at our football club.

“He represents what we want to stand for on and off the field, and will continue to play a key role for us."

Mills follows fellow QBE Sydney Swans Academy player Isaac Heeney in recommitting to Sydney in 2017.
