The 21-year-old was a revelation in defence for the Lions in 2021 as he switched from a small forward role to a running half-back.
His transition to defence was smooth as his natural ability to read the play and distribute the ball effectively provided a solid foundation for Brisbane's transitions into attack.
Lions General manager Danny Daly expressed his excitement for Coleman's future at the club.
“He has shown great improvement over the last two years and was able to cement a spot in our backline in the back half of the 2021 season and play some quality football in that time," Daly said on the announcement.
“We are excited in what lies ahead for both the club and for Kiddy in the coming years.’’
'Kiddy' played 18 games this season, cementing his place in the best 22 before the run into finals. He hit peak form in his final two outings for the season, being listed in Brisbane's best on ground.
Coleman reflected positively on his time at the club, making a point to say he enjoyed the culture and the club environment.
“For me, it was the club in general and the culture they have created that made it such a simple decision,’’ he said.
“There are no egos, you quickly learn that everyone in the footy department has an important role to play and everybody in there is valued.
“Everyone helps each other out, the way people stop and help the property guys load things or the way the players clean up the sheds, that is the kind of environment I want to be in."
After a slow start to his AFL career, missing a selection at the 2018 NAB AFL National Draft, Coleman has been made to earn this two-year deal.
