Asked why Queensland MP George Christensen had been allowed to persist with anti-vaccination comments, Mr Morrison said he was "allowed to speak his mind" – but that Australians shouldn't listen.
"I don't think I could have been any clearer yesterday - don't listen to him," Mr Morrison said.
"He is not a doctor, he can't tell you what to do with vaccines.
"Australia is a free country, you can't go around locking people up for what they say as Australians. I'm sure the media wouldn't be suggesting we do that.
"He is allowed to speak his mind but Australians should be listening to it."
