Mundine quit the NRL in 1999 after playing 127 matches which included three games for NSW.

He took the Dragons to the 1999 grand final but was snubbed for the Kangaroos touring squad despite his dynamite club form.

The 41-year-old two-time boxing world champion said his outspoken nature took centre stage instead of his playing prowess which believed led to a series of selection snubs.   

“I talked out from the get go because they’d never given me my props in league,” Mundine told Fox Sports News 500.

“They’d never give me my props. I whipped (Laurie) Daley, I whipped (Brad) Fittler. Continuously. Not one time, two times, three times, four, five. I’m talking five years. Over five years straight.

“It cut me deep, man. They had to pick me in the State of Origin and then they messed me around; playing me off the bench, playing me in positions I’d never played before — in the forwards, in the hooking role.

“When I left in 1999, early 2000, at the end of ‘99 they took a team to England. They don’t pick one squad, they pick two squads, like 42 players to go — and I wasn’t even part of that.

“And I was the best statistically that year. We made the grand final and I whipped what they called the best in Brad Fittler all year. And my statistics were second to none. That’s why I left.

“It just bothers me, man. I just hope it changes. I just hope it changes for the next generation to come. It just ain’t fair. No equality, man.”

Mundine is set to take on long-time boxing rival Danny Green at the Adelaide Oval in 2017.
