The World Health organisation (WHO) has issued a stark warning to countries which are lifting Covid-19 restrictions at a rapid rate.
The warning came just hours after both New South Wales and Victoria made announcements which will see the states scrap most of their public health measures.
Both states have allowed dancefloors to return and removed density limits on hospitality and entertainment venues, and masks and QR code check-ins will only be required in limited circumstances.

Despite the Premiers of both states voicing optimism about the new state of play given infection numbers, vaccination rates and hospitalisations, the WHO warned relaxing restrictions in some cases was 'premature'.
"I'm a bit nervous right now, that we're just sort of lifting everything," Dr Michael Ryan, who is the executive director of WHO Health Emergencies, said.
"If we get hit with another variant, and we've already sort of abandoned all measures, it's going to be really hard to put anything back in place," he added.
"This idea that we're just going to abandon everything, I think is a very premature concept in many countries right now."
Dr Maria Van Kerkhove, Covid-19 technical lead of the WHO Health Emergencies, program echoed these sentiments.
She said it is 'ill-advised to lift everything all at once'.
"We just need to have countries to not do this all or nothing approach because it is confusing," she said.
"In some countries they're in a better position to be able to do that because they have higher levels of vaccination coverage, high levels of population-level immunity.
"They have the ability to adjust."
