Joining for her regular paid appearance on the show, the One Nation leader was discussing the controversy surrounding an anti-vaccination event at Melbourne Zoo.
"If the other kids have had their vaccinations whats the problem here?" she asked.
"Of course these people can travel to the zoo and go to the zoo... These people are in shopping centres, they're around the place."
She went on to urge for a "common sense debate" about vaccination, criticising the government for a nanny-state approach to the issue.
But it was when she said she would reconsider vaccinating her kids that things really took a turn.
