Anti-vaxxers have been targeting Sydneysiders by dropping leaflets in letterboxes that claim the novel coronavirus is a hoax and by spreading conspiracy theories online.

Some residents of Ryde received a 12-page printed document in their letterboxes calling the pandemic the "plannedemic" and advising people not to follow advice to get a seasonal flu shot and challenge the government over physical distancing rules.

The document, seen by the Herald, said COVID-19 was just a mild seasonal cold and was being exaggerated as part of a conspiracy to remove social freedoms and introduce forced vaccinations.

The document alleges that a cast of villains, including Bill Gates, Rupert Murdoch, Lucy Turnbull, the World Health Organisation, the World Bank and Big Pharma, had a secret agenda that would culminate in hiding identifying nanoparticles in the vaccine to exert global domination.
