It’s the new black among anti-vaxxers -- a magical phrase that they believe will help them overcome the reason and evidence supporting the benefits of vaccination by tapping into obscure constitutional powers.

In September, the government began a Senate inquiry into its “no jab, no play” bill, despite it being non-controversial and backed by Labor and the Greens (in fact it passed the Senate today, unamended, after the committee reported on November 11). The inquiry hearing -- chaired, for his sins, by ACT senator Zed Seselja -- in Brisbane three weeks ago descended into farce as anti-vaxxers like Meryl Dorey queued up to attack vaccination and argue No Jab, No Play was a conspiracy by Rupert Murdoch to impose compulsory vaccination. When Greens leader Richard Di Natale asked why the likes of Dorey were referring to the “Australian Vaccination Network”, a name they have been legally obliged to no longer use, he was accused by one Brett Smith of being part of the Murdoch conspiracy, perhaps the first time that anyone has proposed a link between Murdoch and the party that his newspaper The Australian said needed to be “destroyed”.
