Warning to remain vigilant with coronavirus as weather warms

Australia's Deputy Chief Medical Officer has warned people not to be complacent with coronavirus as the weather warms up.

Dr Nick Coatsworth said it is unclear what effect the warm weather will have on the virus and Australians should continue to practice the same safety measures.

The warning comes as Sydney temperatures are expected to reach 29C tomorrow, while Townsville and Darwin will reach 28C and 31C respectively.

"We have to be clear we do not yet know the impact of the seasons on COVID-19," Dr Coatsworth said.

"We absolutely cannot assume that because we're moving into the summer months, when other respiratory viruses traditionally decrease, that COVID-19 would also decrease."

Dr Coatsworth said all Australians should be able to "get out and enjoy the warm weather" when summer months approach but warned everyone needs to remain vigilant.

"Australians will get outside - and they should in the states where they're able to do so, and as restrictions are lifted in Victoria," he said.

The top doctor said there are two important things that impact coronavirus transmission that will need to remain front of mind.

"One is movement of people across cities, across states, and the second one is crowds which we see frequently."

He said crowds bring a potentially deadly risk.

"We have seen in the Northern Hemisphere COVID running rampant across many nations during the summer months," Dr Coatsworth said.

"As holiday-makers go to and from countries in Europe, bringing the disease back in to their own country and sparking new outbreaks of COVID-19.

"So, the message is, as we move into the summer months, treat the summer with as much caution as you've treated winter.

"That means keep physical distance. That means get tested if you're at all unwell.

"Don't go to a family gathering down at the beach if you're unwell or the kids are unwell.

"Stay at home and get yourself tested. Wear a mask if you're on public transport going to and from those areas."
