Brooks will play his final home game for the club against the Dolphins on Saturday before leaving for Manly next year.
The 28-year-old has become a whipping boy for the Tigers' woes over the last 11 seasons but the fact the joint venture has cycled through five permanent head coaches in that time hasn't helped his cause.
Benji Marshall is set to step up as head coach in 2024 after current mentor Tim Sheens' decision to move aside at the end of this season.
But Brooks warned Marshall could only do so much, pointing to the club's bumbling administration as a reason for the Tigers' 12-year finals drought.
Brooks' camp was frustrated they were rushed into a decision over his future earlier this year when he was given a deadline while weighing up between an extension or a move to Manly.
"When they did that it made my mind up," Brooks told reporters.
Asked what needed to change at the Tigers, Brooks said: "Everyone being on the same page and making decisions, and the right decisions, for the club to go forward.
"I don't know who makes the decisions here, it's hard to say.
"There's always something going on. I guess (after) 10 years here, I'm sort of used to it."
Brooks' dig at the club's hierarchy follows an 18-month period of turmoil headlined by the sacking of previous coach Michael Maguire.
The former Souths mentor was axed by Sheens, who had been brought in as the Tigers' head of football and was then installed as head coach.
Sheens and Maguire clashed over football decisions before the latter's sacking and there has been similar friction between Marshall and newly appointed recruitment boss Scott Fulton.
The pair have already clashed over recruitment decisions.
Prop Stefano Utoikamanu said Marshall commanded the respect of the Tigers squad but conceded the rookie coach would be under immense scrutiny.
"It's been pretty s**t this season," he said of a campaign that looks likely to end with a second successive wooden spoon.
"He's been good trying to keep us on track for the year.
"Anyone coming into the head coach role is going to have a lot of pressure on them."
