The family of a man who died overnight in Perth of the coronavirus have issued a statement urging Australians to take the disease seriously.
Ray Daniel, 73, collapsed in his home on Wednesday morning and was dead within 48 hours.
His family said he was a "very fit, healthy and active man with no known underlying health issues" and that he showed no significant signs of being unwell.
"Clearly this virus does not discriminate and we never believed for one second that it would take him from us," the family said.
"Everybody needs to take this virus seriously and follow the health advice that is being given."
The family thanked the hundreds of people who had offered them support in their grief, and also the paramedics, doctors and nurses who worked hard to save his life.
"We as a family are completely devastated by the sudden death of our father, husband and grandfather," they said.

Premier Mark McGowan today asked residents for "patience and understanding in what is an unprecedented situation.
Specially-organised planes and secure convoys of private buses will be used to fly home international passengers aboard the cruise ships Artania and Vasco De Gama.
Australian passengers aboard the latter will be quarantined on Rottnest Island or in a Perth hotel for 14 days.
The Magnifica, which is also in Western Australian waters, will leave once it has re-provisioned, Mr McGowan said.
The premier also gave notice of new travel restrictions inside Western Australia from mid-Tuesday.
Regional borders will be put in place and people not on non-essential travel will be forbidden from crossing them, under penalty of a possible $50,000 fine.
Exemptions will be in place for those travelling to deliver essential goods, for health and emergency reasons, and on compassionate grounds.
But the message, Mr McGowan said, was "do not travel around Western Australia".
He urged travellers within the state to return home immediately.
Gun shops and firearms dealers will also be closed down in the interests of "community safety".
Mr McGowan said farmers would still be able to access ammunition for pest control and animal welfare purposes, under "strict conditions".
