Regarded as one of the country's finest cricketers, Marsh played 96 Tests for Australia between 1970 and 1984 and later served as a national selector until 2016.
In a statement released on Sunday, the 74-year-old's son Paul gave a worrying update about his condition.
"He is currently in the fight of his life and remains in an induced coma in critical condition," the statement read.
"At the moment this is a waiting game and we are unlikely to have any certainty for some time.
"We know there is a lot of interest in Dad's condition and our family has been overwhelmed by the messages of love and support from all around the world.

Cricket world rocked by Rod Marsh news
Australian Test captain Pat Cummins was told the news of Marsh's condition when he addressed the media upon his team's arrival in Pakistan for their six-week tour there.
"We just really feel for the Marsh family and the kids," Cummins said.
"He's a legend of our game and somebody who has done so much for our sport. We obviously wish him the best because it's a really tough situation."
The Aussie wicketkeeping great was in Bundaberg for an event for the Bulls Masters charity group, when he suffered the heart attack in a car with organisers John Glanville and David Hillier.
The pair were praised as heroes after driving Marsh straight to the hospital instead of waiting for an ambulance.
"John and Dave deserve so much credit because the doctor said if they had waited for an ambulance he would not have made it," Bulls Masters boss Jimmy Maher told News Corp.
"Rod landed at 10.05am and rang me from the car at about 10.30.
"He said he could not wait to have a beer with me.
"Then soon (after) Dave rang me from the car and told me what had happened. It's devastating."
Marsh played 96 Tests for Australia between 1970 and 1984, snaring 355 dismissals behind the stumps.
