Genomic testing has confirmed two more overseas travellers who recently arrived in New South Wales in Australia have been infected with the Omicron variant.
That brings the total number of Omicron cases in the state to four.
Both passengers arrived in Sydney from southern Africa on Singapore Airlines flight SQ211on Sunday. They are fully vaccinated and isolating in Special Health Accommodation.
Everyone on the flight is considered a close contact and will need to get tested immediately for Covid and isolate, NSW Health says, regardless of their vaccination status.
NSW Health is contacting all passengers and flight crew to advise them of isolation requirements.
