Former undisputed heavyweight boxing world champion and convicted rapist Mike Tyson says he was never comfortable about waiting for permission to enter Australia, but is adamant no question about his chequered life will be too difficult to answer on his upcoming tour.
Tyson has this week been granted a visa from the Australian government allowing him to proceed with a whirlwind speaking tour spanning five cities in six days.
He is still waiting to find out if a second application to enter New Zealand for one event in Auckland will be granted after a special visitor's visa was granted but cancelled a few days later.
Speaking from the United Kingdom, where he is currently touring with his show, Tyson was never totally confident he would be admitted to Australia, even though he'd been allowed into numerous countries since serving his prison sentence.
"I'm never comfortable about being in somebody else's hands, the responsibility of having my life in their hands," Tyson told AAP over the phone.
"I'm not comfortable with that, because people go out of their way to hurt celebrities so they can get their name in the paper and they can be big shots and that stuff scares me a lot."
His Day of the Champions tour, which takes in shows in Brisbane, Sydney, Melbourne, Adelaide and Perth from November 16-21, will allow Tyson to give his version of his tumultuous life.
"They can expect a collection of good entertainment stories talking, getting to know me as a really good person," Tyson said.
Audiences will have the chance to ask him questions and Tyson has stressed no topic is off limits.
"I don't have a question that's difficult to answer that I'm embarrassed or ashamed of," Tyson said.
"You know why I know? I know that we're all going to die one day and in the whole spectrum of the world we're not really a big matter."
