The family of the survivor from a group of four people hospitalised after consuming a meal of poisoned mushrooms, has thanked hospital staff and the public for their support.
Baptist church pastor Ian Wilkinson lost his wife, 66-year-old Heather Wilkinson after the pair ate the mushrooms at a lunch at a Leongatha home in Victoria's southeast on July 29.
Ms Wilkinson's sister Gail Patterson, 70, and brother-in-law Don Patterson, 70, have also died in hospital.
In a statement released on Sunday night, the family of Ian Wilkinson said they wanted to thank the Austin Hospital staff for their unwavering care and support, as well as members of the public who've sent cards and letters.
"We are deeply moved by the outpouring of kindness, prayers, and support from friends, family, and the broader community," it read.
"Your thoughts and well-wishes have been a source of strength and comfort to us all.
"As we navigate this difficult journey, we kindly request that our privacy be respected. We need space to grieve, support one another, and care for Ian without public intrusion."
The 70-year-old is still critical but in a stable condition at the hospital in Melbourne's northeast.
The Pattersons' daughter-in-law, who police say cooked the meal at her home but did not become ill, has been interviewed by investigators.
She was released without charge but police said she remains a suspect.
