Spent her later life raising millions for charity
Olivia Newton-John’s last gig was for charity two years ago.
The UK-born singer, who died aged 73 from cancer on Monday, last appeared before fans at Sydney's Accor Stadium for the Fire Fight Australia concert in February 2020.
She took to the stage to sing a duet with John Farham as she fought cancer which had spread to the base of her spine.
The 10-hour charity event raised $9.5million in the wake of the deadly Black Summer Bushfires of 2019-2020.
Olivia's husband John Easterling announced the news of the Grease icon's death on Monday morning.
He revealed the actress and singer's final request was for donations to be made to the Olivia Newton-John Foundation Fund in lieu of flowers.
Her battle with breast cancer first began in 1992 when she was just 44 years old.
She was open about her diagnosis and treatment, which famously included the use of medical marijuana.
Her cancer returned in 2013 and again in 2017.
In a statement, the hospital that runs the Olivia Newton-John Cancer Wellness and Research Centre in Melbourne - which was opened after the star's campaigning - said she "encouraged, inspired and supported" staff and patients everyday.
"We are incredibly grateful for the special relationship we had with Olivia for many years. Her generous support and gift provided hope and changed the lives of thousands of cancer patients.
“She was the light at the end of the tunnel for many, many people."
