Australia suffered its deadliest day of the pandemic on Tuesday as an omicron outbreak continued to push up hospitalisation rates to record levels, even as daily infections eased slightly.

Australia is dealing with its worst COVID-19 outbreak, fuelled by the omicron variant of the coronavirus that has put more people in hospitals and intensive care than at any time during the pandemic.

As many as 74 deaths were registered by late morning between New South Wales, Victoria and Queensland, Australia’s three most populous states, exceeding the previous national high of 57 last Thursday, Reuters reported.

“Today, is a very difficult day for our state,” New South Wales Premier Dominic Perrottet said during a media briefing as the state reported 36 deaths, a new pandemic high.

Perrottet, who has consistently ruled out any tough curbs due to high vaccination levels, said hospitals can still cope with the rising number of admissions. “Despite the challenges, they are not unique to the rest of the world,” he said.

Victoria on Tuesday declared a “code brown” in hospitals, typically reserved for shorter-term emergencies, that would give hospitals the power to cancel non-urgent health services and cancel staff leave.
