Covid hospitalisations in NSW have doubled in the week since Christmas and are expected to rise even further as a rampant Omicron outbreak tests assurances the state's health system can manage the surging load.
Sunday's 1066 hospitalisations are up from 388 hospitalisations reported on Christmas Day and 458 on Boxing Day, while the number of people in intensive care has risen by 30 – from 52 to 82 – in that time.
Victoria recorded 7172 new cases on Sunday down slightly from the daily record 7442 posted on New Year's Day.
Three more people in Victoria died, while 472 patients are in hospital.
Political opponents have savaged the NSW government in recent days for its handling of the Omicron surge, particularly how it is resourcing an increasingly under-pressure health system.
Premier Dominic Perrottet and Health Minister Brad Hazzard have consistently stated that the state's health system is in a solid position despite the dramatic rise in infections and mayhem caused by an explosion in testing demands.
However, a decision to pare back isolation requirements for hospital staff has been described as a sign the system is coming under intense pressure.
NSW Health revealed on Friday that health workers classified as close contacts will be permitted to leave self-isolation in exceptional circumstances to ensure hospitals and testing clinics are not disrupted.
Queensland broke its daily case record on Sunday with 3587 new infections across the state.

The ACT also recorded a pandemic-high figure with 506 new cases.
