Israel Folau isn't the only Australian athlete causing a stir on social media after boxer Anthony Mundine was slammed over his anti-vaccine stance.
On Wednesday, Mundine was labelled a "peanut" and "extremely dangerous" for his social media post urging his followers against vaccinating their children.
Mundine claimed the Australian Government was bullying parents into getting their children vaccinated.
"Don't vaccine your kids period! The government bull you into vaccine! [sic]' he wrote to his Twitter followers.
"Do your research on the s**t & watched the documentary vaxxed." [sic]
The 43-year-old then shared a link to his Facebook page which showed a video from New York radio show The Breakfast Club, where the hosts claimed that vaccines could cause autism.
His posts caused plenty of outrage, with Australian Paralympian Kurt Fearnley calling the boxer a "peanut."
"You can't make this shit up. We became so comfortable that some promote fear in our peace and others promote apathy in what should be feared," Fearnley tweeted.
"You got many mates with Polio? I do. A heap. From countries that didn't have the luxury of vaccinations you peanut."
Others on social media asked Mundine to show his medical degree; otherwise, his opinion doesn't matter with fellow users wanted his post to be taken down by Twitter.
Mundine's comments come after a Sydney University student became the 35th case of measles in the New South Wales state since Christmas, while data shows Australia is experiencing its highest number of cases in five years.
Federal Health Minister Greg Hunt said the community should ignore Mundine's dangerous and ignorant views.
"I have no time for anti-vaxxers, and the message they are sending is extremely dangerous," Mr Hunt told The Sydney Morning Herald
"This includes high-profile individuals who spread dangerous information about vaccines on social media.
"The science is in - vaccines works. They save and protect lives."
