New Brisbane coach Michael Maguire has cited his hunger to win another competition as a primary reason for ditching NSW and re-entering the NRL.

Maguire was officially unveiled as the Broncos' head coach on a three-year deal at the Brisbane club's headquarters on Tuesday alongside CEO Dave Donaghy.

He enters the role after being released from his duties with the Blues' State of Origin side.

His appointment also comes just five days after Brisbane sacked club legend Kevin Walters.

Maguire said he enjoyed Origin coaching "immensely" but craved being a club coach once again.

"I am a career coach," he said.

"I love the daily stuff and my last campaign in the Origin — it was an incredible experience — but I've missed having players around me daily, and that's what I've got a lot out of living as a coach," he said.

Maguire's appointment marks a stunning turnaround for the 2014 premiership winner, who was sacked by the struggling Wests Tigers midway through 2021.

He has since won a Pacific Championships with New Zealand and an Origin series with NSW, before now returning to club land with 2023 grand finalists Brisbane.

"It did happen quick, but clubs move and circumstances happen," Maguire said.

"I'm extremely hungry to win another competition.

"I just see the opportunities and the ability of what a club like the Broncos can be — [and] you can get pretty close to it."

Maguire's immediate challenge at Brisbane will be pulling the playing group into line, with questions swirling about their attitude following their defeat in last year's grand final.

The club's drop to 12th place on this year's ladder marked one of the greatest slides in premiership history, despite it having one of the NRL's most star-studded rosters.

Maguire is also bound to face challenges from the Broncos' all-powerful old boys club.

Four years after Anthony Seibold noted their "agendas" on his way out of Brisbane in 2020, it is already clear things will be difficult for another outsider.

Broncos legend Shane Webcke last week questioned why the club would sack Walters. Gorden Tallis also slammed the decision on Monday night.

"I don't think he (Maguire) is better than Kevin," Tallis said on NRL 360.

"The people who are running the club — Wayne Bennett wasn't good enough but he was good enough for Souths.

"Seibold, who has done a great job at Manly, he wasn't good enough.

"Kevvie wasn't good enough. They keep on moving on coaches. The club is not going to move forward."

Maguire smiled through questions about Brisbane's old boys and said he had a good relationship with Tallis.

His move leaves NSW back at square one, after only appointing him Origin coach last summer.
