Australian comedian Magda Szubanski in remission from cancer

Australian actress and comedian Magda Szubanski says she is in remission, after receiving treatment for a rare and aggressive cancer.

Szubanski is best known for her iconic role as Sharon Strzelecki in the Australian sitcom Kath & Kim, and for her film roles in Babe and Happy Feet.

In May last year, the 64-year-old announced she had diagnosed with stage four Mantle cell lymphoma, a "fast-moving" form of blood cancer.

In an update to her social media on Friday, she said had completed chemotherapy: "Seems I'm not dead... So, phew, big relief."

"It's not a cure, but because I got a good remission, that hopefully means that I'll keep the cancer at bay for a good long time."

Szubanski rose to fame playing the netball-loving Strzelecki in the early 2000s, and has been a stalwart of the comedy scene in Australia since.

She was also a prominent advocate for the legalisation of same-sex marriage in Australia.

Her diagnosis triggered an outpouring of support from her peers, including Kylie Minogue and Toni Collette.
