Anthony Mundine says despite all the controversy and criticism thrown in his direction over the journey his mental strength has never wavered.

Now 'The Man' wants to instil that same resilience in disadvantaged youth.

On November 19 he launched the Anthony Mundine Foundation addressing youth mental heatlh at his father's gym in Sydney's Redfern.

The foundation runs alongside his Mundine Mindset program, aimed at instilling in young people a core of self belief similar to that which served the rugby league premiership winner and three-time boxing world champion throughout his career.

The proud Aboriginal man aims to mentor kids of all backgrounds, Indigenous and non-Indigenous, towards acheiving the best outcomes possible with strength of mind as a key ingredient.

He said his success has long served as a positive example of achievement through adversity for others to emulate.

"A lot of people see the TV or they see the success and say he's talented or whatnot but they don't know the depths that go through my story," Mundine said.

"I want to give back to the people, to the kids, to the youth, all I can," he said.

"That's why I started the foundation, right? I know my story changes people's perceptions on life.

"All that negativity within the media didn't affect me in any way shape or form."

Mundine launched the non-for-profit with the open offer to the public of laying a punch on the former champ to drive awareness toward the campaign.

Asked if any of the shots rocked him, the answer was simple.

"Nah," he laughed.

Mundine is hopeful of securing a healthy level of funding for the foundation.
