A great-grandfather from Victoria could be the oldest coronavirus survivor in Australia after he beat the virus at the age of 100.

Roy Bartlett spent his 100th birthday in hospital away from family and beat the virus in the process.

“The whole family are forever in debt to them for taking care of him,” Bartlett’s granddaughter Lauren Penrose told 7NEWS.

“Placing their own lives at risk and the lives of their own family to look after him.”

His wife of 70 years Lorna passed away in November last year. Roy then contracted pneumonia and then coronavirus.

His granddaughter is in awe of his resilience.

“He’s definitely a true Aussie battler,” Penrose said.

“Always surprises us and always beats the odds.”

She explained that her family's experience shows that each COVID-19 case is different.

“They may be someone’s grandfather, and they may be 100 years old, but they’re part of someone’s family, and they’ve got loved ones and they really truly do matter.”
