Szubanski, who rose to fame playing the character of Sharon Strzelecki in Aussie television series Kath and Kim, revealed the tragic news in a post on Instagram this afternoon.

Szubanski’s loved ones and friends were quick to voice their support.

“Lots of love and support to you, beautiful one,” comedian Rove McManus commented on her post.

Actor Sam Neill, who is in remission from blood cancer, said, “Right there with you darling.”

Neill and Szubanksi both starred in the 2019 film Ride Like A Girl.

“I’m so sorry to hear this Magda, but this cancer has no idea what it’s taken on does it?” former A Current Affair Host Trace Grimshaw said.

“You come from strong, odds-defying stock, and you’ll beat this.”

Today host David Campbell said “I love you so bloody much.”

Former The Project host and radio presenter Carrie Bickmore, who lost her husband Greg Lange to brain cancer in 2010, told Szubanski, “You’ve got this.”

“Yelling at you now from a distance that we all love you,” Bickmore said.

Hugh Sheridan, who starred alongside Szubanksi in the Australian production of A Funny Thing Happened on the Way to the Forum and hosted her on the 2012 TV series I Will Survive said, “I love you so much Magda”.

“Massive hugs being sent to you and so many more in person to come,” the actor wrote.
