Anti-vaxxers have allegedly scammed their way into a Gold Coast school under the pretence of holding a seminar about organic vegetables.

But what Miami State School students got was something very different.

The anti-vaxxers instead screened a film about their unfounded beliefs that there is a link between autism and childhood vaccinations.

Queensland premier Annastacia Palaszczuk is demanding answers as to how the documentary came to be shown at the school on Tuesday night after organisers told school officials they were running a seminar on organic vegetables.

She said the organisation made “misrepresentations” to the school, and she would be speaking with Education Minister Kate Jones on Wednesday to get to the bottom of the matter.

“My initial advice is there has been some misrepresentation from that organisation to the school in question where they conveyed to the principal that they were to be conveying information about organic produce,” the premier told reporters on the Gold Coast on Wednesday.

“I don’t think they were very clear in their purpose and I don’t think they should have been allowed to present in such a manner.”

The organisers of the film have previously gone to extreme lengths to keep the location of screenings a secret in an effort to keep them from being shut down, amid strong opposition from Australian health professionals.

Maybe the Australian government and public should apply similar critical faculties to anyone claiming to purport the benefits of organic production.
