A highly controversial anti-vaccination documentary slammed by health authorities is being shown in Newcastle tonight.
However organisers are refusing to say where Vaxxed - From Cover Up To Catastrophe is going to be screened, in a bid to avoid protesters.
Those who've bought tickets will receive a text message two hours beforehand revealing the exact venue.
The film's been shown in Queensland in recent days as part of a national tour, generating public outcry and calls from doctors for it to be banned.
Organisers were accused of tricking a Gold Coast principal into letting them hire out his school hall to show the film, after claiming it was a seminar on organic vegetables.
The film has been banned from being shown in cities around the world.
