WATCH CENTRAL COAST MARINERS v BRISBANE ROAR LIVE ON SBS ONE, HD and ONLINE on FRIDAY 13 FEBRUARY FROM 7.30pm AEDT

After joining the club as a National Youth League player in 2011, Brown joined the professional ranks in January 2013 and impressive performances in the first team has seen him rewarded with a new three-year deal.

"I'm a Brisbane boy, I've got a lot of passion for this club so it's great to sign for the next three years," the 21 year-old said.

"It was an easy decision for me – my hometown club, it's a great environment to learn and develop, and I'm around my family and the lads."

Brown credited interim coach Frans Thijssen - who replaced Mike Mulvey at the helm late last year - with "recharging" Roar as the defending champion targets a move into the top six by making it three straight wins after the Asian Cup break when it visits Central Coast Mariners on Friday night.

The Mariners will be without striker Mitchell Duke, who has transferred to J.League outfit Shimizu S-Pulse, but former Adelaide United winger Fabio Ferreira is set to make his first appearance for his new club.

"They're having an average season but they're always dangerous," Brown said of the Mariners.

Frozen out of the team during Mulvey's reign, Brown has made nine starts since Thijssen took over with veteran Shane Stefanutto shifted to central defence after the departure of skipper Matt Smith.

"The new coach has come in and has new ideas and a new philosophy. I think it's recharged the team," Brown said.

"He's sort of just come in and said the best 11 players (will play), no matter how old you are, no matter what experience you have.

"Obviously we've had a few injuries when he first came in which gave a lot of the younger boys a chance."

A Queensland Academy of Sport and Australian Institute of Sport graduate, Brown is the son of ex-Socceroos striker Rod and has big ambitions for the future.

"This is the best place for me to develop and become a better player," the Australia U-23 international said.

"It's shown now that you don't need to leave the A-League to become a Socceroo – the likes of Matt McKay and Ivan Franjic have shown that if you're performing well in the A-League and at this club, that you can get call ups to the national team.

"It's a massive ambition of mine to play for the Socceroos one day and I feel that being here can help me reach my goal."

Brisbane Roar Director of Football Ken Stead said Brown’s new contract exhibited just how the three-times A-League champion was committed to the development of young footballers in Queensland.

"Corey is a prime example of this – he captained the Young Roar, he made his senior debut in the AFC Champions League in 2012 and now is performing at a consistently high level for our A-League side," Stead said.
