The lawyer attempting to stop mandatory COVID-19 vaccinations for health workers is one of the directors of the Covid Medical Network, corporate documents show.

Tony Nikolic has made national headlines with his Supreme Court challenge to the NSW state government’s declaration that all health workers — including non-clinical staff, such as cleaners — have to get vaccinated by 30 September or lose their jobs.

Since 20 July, he has also been a corporate director of the Australian Medical Network, the organisation behind the Covid Medical Network website, according to ASIC documents.

The document lists the other directors as Melbourne GP Dr Mark Hobart and Dr Robert Brennan, a doctor in Queensland.
