US President Donald Trump's coronavirus diagnosis is being used as a reminder no one is immune while Victorian authorities are on high alert after "selfish" beachgoers flouted social distancing rules in Melbourne.
Mr Trump on Friday confirmed he and wife Melania tested positive for COVID-19, just weeks out from the US election.
He was later moved to hospital where he will stay for a few days "out of an abundance of caution".
Cabinet minister David Littleproud said on Saturday Australia wished the pair a speedy recovery.
"It demonstrates that no one is immune from catching COVID-19," he told the ABC.
"No matter the precautions, we are all susceptible to this and it is important that we understand that as a global community."
This was echoed by Labor frontbencher Jason Clare who said it served to remind how contagious the virus is.
"The most protected man in the world couldn't be protected from this virus. The Secret Service can stop a bullet but they couldn't stop this," he told reporters.
Meanwhile, footage of crowds flocking to St Kilda Beach in Melbourne on Friday has angered Victorian Premier Daniel Andrews who labelled the behaviour as selfish, dumb and illegal.
The vision showed people breaching social distancing requirements and mask-less beachgoers kissing the camera and then a reporter on the head several times.
Elsewhere a limited travel deal has been announced with New Zealand, with Kiwis allowed to visit NSW and the Northern Territory from October 16 without quarantining.
Exempting them from mandatory two-week hotel stays would free up 325 quarantine places a week for Australians.
But Deputy Prime Minister Michael McCormack said other states could only be included if they signed up to the hotspot definition.
A hotspot is anywhere that has recorded more than three cases a day over three days.
South Australia is likely to be next to join the bubble when its government signs up.
Queensland and Western Australia have resisted the Commonwealth's demands, with the definition centred on triggers for opening state borders.
Kiwi leader Jacinda Ardern poured cold water on the travel deal, encouraging New Zealanders to travel locally.
She said New Zealand was not yet ready to accept Australians due to the risk of coronavirus.
Tourism Industry Association of New Zealand chief Chris Roberts doesn't expect Kiwis to buy a ticket across the Tasman unless they need to return to Australia.
New Zealanders still have to pay for 14 days hotel quarantine when returning from Australia.
Mr Roberts says the announcement has as much to do with Queensland as it does New Zealand.
"It looks to us like the federal government and the NSW government looking to put a bit of pressure on Queensland to open up some of those state restrictions," he told the ABC.
"So New Zealand might be getting used a little bit here; we're OK with that if it opens up the door and we can actually get to somewhere sensible. We'd love to see lots of Australians heading over here before Christmas."
Locally, from November 1 Queensland will allow people from NSW to enter without quarantining, provided there is no further unlinked community transmission.
Tasmania is likely to open its borders to all states except Victoria from October 26.
Victoria recorded just eight new cases of coronavirus on Saturday, along with three deaths, taking the national toll to 893.
