The 71-year-old Muriel's Wedding star was admitted to a facility in Melbourne on Monday (16May11) and his loved ones have flocked to his side after doctors informed him they would not be able to operate.
His manager, Mark Morrissey, announced the news on Australia's Today Show on Wednesday morning (18May11), saying, "Sadly, he has cancer, and it's inoperable. He was admitted to a hospice a couple of days ago."
Hunter worked with Mel Gibson in Gallipoli and also appeared in The Adventures of Priscilla, Queen Of The Desert. He played Toni Collette's father in Muriel's Wedding and starred opposite Nicole Kidman and Hugh Jackman in Australia.
He has also voiced parts in Finding Nemo and last year's (10) Legend of the Guardians: The Owls of Ga'Hoole.
