NSW Health has confirmed two people who flew into Sydney about 7pm from southern Africa have since tested positive to COVID-19, which has been found to be the Omicron strain.
Both travellers are fully vaccinated against COVID-19 and are asymptomatic. They are in isolation in the Special Health Accommodation.
The travellers were among fourteen people from southern Africa who arrived on Qatar Airways QR908, Doha to Sydney.
The other 12 passengers from southern Africa are undertaking 14 days of hotel quarantine.
Around 260 passengers and air crew on the flight are considered close contacts and have been directed to isolate.
Border restrictions introduced yesterday mean any Australians who have been in South Africa, Lesotho, Botswana, Zimbabwe, Mozambique, Namibia, Eswatini, Malawi, and the Seychelles in the past 14 days must enter hotel quarantine for 14 days, irrespective of their vaccination status.
