A Tasmanian woman has been declared Australia's oldest mum after giving birth to her first child at the age of 63.
The woman delivered a baby girl via Caesarean section at Melbourne's Frances Perry House private hospital on Monday.
The woman and her 78-year-old husband reportedly conceived abroad via IVF, Seven News reports.
The couple reportedly underwent several failed IVF attempts here in Australia before heading overseas where they had a donor embryo implanted.
The baby was delivered premature at only 34 weeks, but both mum and bub are reportedly doing well.
At 63 years of age, the unidentified mother became the oldest woman to give birth in Australia. The previous record-holder was 60 when she had a child in 2010.
The oldest woman in Australia believed to have delivered a naturally-conceived child was 50 when she gave birth in 2011.
Despite the happy news for the unidentified Tasmanian couple, one academic has slammed the use of IVF treatment for women over 53 - which he considers to be the "end of natural pregnancy".
"That child will need looking after for 20 years, and there’s a possibility she won’t be able to do that," Monash University professor Gab Kovacs told The Mercury.
"Our bodies weren’t designed to have children in our 60s. I don’t think any responsible IVF unit in Australia would treat someone of that age, and it’s not a standard of medicine I would condone."
