A woman who lost her entire family in a head-on crash on the Princes Highway on Boxing Day was still fighting for life in hospital on Friday morning, the hospital said.
It's understood the life support for actor Jessica Falkholt was due to be switched off on Thursday night, but early on Friday morning, the hospital said she remained in a critical condition.
The 28-year-old has been in St George Hospital with serious injuries since the fiery Boxing Day collision near Ulladulla.
She had been riding in a car with her father Lars 69, mother Vivian, 60, and younger sister Annabelle, 21, on the morning of December 26, 2017 when it was hit head-on by a four-wheel-drive that veered onto the wrong side of the road near Ulladulla at about 10.45am.
Lars and Vivian died instantly on impact, while bystanders managed to pull Jessica and Annabelle from the wreck.
Home and Away, on which Jessica had her break-out role, posted on social media on Thursday night: "Rest in peace, beautiful Jessica Falkholt", with a link to a news story about her life support being turned off.
However, a police spokeswoman said they had not been informed of any change to Jessica's condition either by crash investigators or St George police.
Craig Anthony Whitall, 51, who was behind the wheel of the Toyota Prado, also died on impact.
Both sisters were flown to hospital, but Annabelle died after her life support was switched off days after the crash.
Hundreds of mourners attended the funeral for Annabelle and her parents at St Mary's Catholic Church in Concord on Wednesday.
In his eulogy, Vivian's brother Paul Ponticello thanked emergency services and the bystanders who pulled Annabelle and Jessica from the wreckage.
"Their lives ending on a highway makes absolutely no sense," he said.
"We take little comfort in knowing that they are together and always will be."
Lars was remembered as a wonderful husband and father, and Annabelle was remembered as a loving and kind person.
"She loved to laugh and the sound of it is something many of us will carry for the rest of our lives," her close friend Brittany Macchetta told the funeral service.
The Falkholts were travelling back to Sydney after a short Christmas break when they came into the path of Mr Whittall, who was on his way home from a methadone clinic.
Mr Whitall, who was known to police, was making the hour-long drive home to Ulladulla after visiting the clinic in Nowra on Boxing Day morning.
About 50 kilometres into the 65-kilometre trip, as he neared the Bendalong turnoff, his four-wheel-drive failed to negotiate a sweeping left-hand bend and crashed into the Falkholts' Mazda.
Crash investigators are examining the cause of the accident and whether methadone played a part.
