Bernard Tomic has denied being too mentally fragile to enter I'm A Celebrity .. Get Me Out Of Here! and accused Tennis Australia of corruption on The Project.

Before leaving the South African jungle, Tomic spoke to Project hosts Waleed Aly and Carrie Bickmore about the reasons for him quitting the show before turning to recent comments from Lleyton Hewitt suggesting he may never return to tennis.

"Yeah I don't care what Lleyton said, I never lost to him," Tomic retorted. "I think the important thing is that the reason why I played the Davis Cup at the youngest age [in] Australian history, there's a reason why my record stands that good.

"I stand by my call, they know they can't win without me and I know that they can't win without me so it's a tough situation, but I wish them the luck and the best of success with the coming tie, but they know where I stand and hopefully in the coming years there could be a chance with me coming back to play."
