IN A HUGE coup for Brisbane, young leader Jarrod Berry has extended his contract by a further four years, locking away one of the Lions' core pieces until the end of 2024.

It's the first time this decade Brisbane has signed a first-round draft pick to such a lengthy deal.

Berry told AFL.com.au the decision was a "no-brainer", saying he couldn't speak highly enough of the culture Brisbane had created since he was taken with the 17th pick of the 2016 NAB AFL Draft.

And in further good news for the 21-year-old, younger brother Tom – drafted last year – has also agreed to a further two years, keeping him at the Gabba until at least the end of 2022.

"How many times are you going to get to sign with your brother? It was a no-brainer for me," Jarrod said.

In a big few months for the older brother, named as the youngest member of Brisbane's leadership group earlier this year, he's just bought his first house and will move in next week, and now has the big contract extension.

His arrival at the Lions coincided with the appointment of coach Chris Fagan and football manager David Noble, a pair he credits immensely with being made to feel welcome.

"You come in so late as a first-year player and hear all these stories about how the club used to function, I knew the history of the club the previous few years, not winning games regularly, it was a bit of the unknown," Jarrod said.

"We were thrown in the deep end a bit.

"The role of Chris and David in that aspect has been pretty large in my career. They've been great for me.

"They've shown me the right way to do stuff. That was the main reason for re-signing,

"I believe in what they're bringing to the table, what they've taught the coaches and what they're messaging is to us players."

Jarrod lived with his best mate from junior days, Hugh McCluggage, but paid credit to the senior Lions for turning the club's culture around.

The strong midfielder has played 43 games since his debut in 2017 and finished sixth in last year's best and fairest.

He said former skipper Dayne Beams was the biggest influence through his first two seasons.

"He really believed in us younger kids that we were going to take the club forward and invested a lot of time in us," Jarrod said.

"He was a standout, but a lot of the boys were really good."

Tom said his transition to the Lions had been smooth, even though he didn't live with his brother straight away.

The teenager has lived with Darcy Gardiner and Lewy Taylor and described it as a blessing, although he'll move in with big brother next week.

"Being put into a household that was lots of fun and with really good guys has helped a lot," he said.

"Jarrod and the club wanted me to develop my own path and own friendship groups and it couldn't have worked out any better.

"Those two boys have been unbelievable."
