Mack was also critical of the talent show format, comparing the process to the Medieval stocks.
"A guy ripped off my act on Australia's Got Talent," he told TV & Satellite Week.
"I don't feel angry about it. If you want to be a comedian and you've gone on national television with material you've stolen, you've already shot yourself in the foot."
Speaking about talent shows in general, he added: "Talent shows are a form of bullying. It's like throwing tomatoes at people in the stocks. For every person whose talent we're celebrating, we're mocking five more."
Mack launches his new Saturday night entertainment format All Star Cast this weekend.
"It's a hybrid of a chatshow and sketch show with stand-up, music and the audience being a big part of the action," he said.
Lee Mack's All Star Cast starts on Saturday at 9.40pm on BBC One.
