Australian officials said there was no need to clamp down on Christmas festivities even as new Covid-19 infections climbed in Sydney, with the country's high vaccination rate helping keep people out of hospital.

Health Minister Greg Hunt said he was confident Australia would not need to follow the Netherlands, which has reimposed a strict lockdown over the Christmas and New Year period to curb the spread of the highly contagious Omicron variant, Reuters reports.

“We're going into summer, we have one of the highest vaccination rates in the world and a very different set of circumstances. So we don't see that's a likely situation in Australia,” Hunt told reporters in a televised media conference.
