New South Wales Health has revealed six overseas travellers who reported being fully vaccinated have tested positive to Covid-19 in hotel quarantine.
The numbers were released in this week's NSW Health Covid-19 surveillance report as the federal government pushes forward with its vaccine passport plans.
The report states six people in the NSW hotel quarantine system tested positive over four weeks ending on May 1, despite reporting they were vaccinated before landing in Australia.
The figures raise concerns about the prospects of a vaccine passport system as Prime Minister Scott Morrison comes under increasing pressure to repatriate Australians stranded overseas.
