Two weeks after a horrific car crash killed her parents and sister, Home and Away actress Jessica Falkholt is clinging to life.
Jessica, 28, and her sister Annabelle, 21, were pulled from the wreckage after their car collided with a 4WD near Ulladulla, on the NSW south coast, on BoxingDay.
Parents Lars and Vivian died at the scene while Annabelle was flown to Liverpool Hospital in a critical condition, where she died as a result of her injuries on December 29.
Jessica remains in a critical condition at St George Hospital two weeks after the crash, a hospital spokeswoman told Daily Mail Australia on Tuesday.

As Jessica remains in hospital, relatives and friends of the Falkholt family prepare to farewell Annabelle and her parents Lars and Vivian at a service on Wednesday.
A funeral service will be held at St Mary's Catholic Church in Concord in Sydney's inner-west.
Jessica's relatives revealed the left side of her brain was damaged, which meant her personality and memory could be affected.
Her relatives admitted they were grappling with how to explain she was the sole survivor of the horror smash.
James Randazzo, Jessica's second cousin's husband, said they were still waiting for her to wake up.

"(Jessica) may wake up and, if she does wake up, is she going to be a different person?" he told News Corp Australia on Sunday.
"If we get to that point then someone is going to have to break the news to her about the rest of her family."
Doctors reportedly told the family it could be weeks or even months before doctors - who removed part of Jessica's skull and kidney - knew how severe the damage to her brain was.
"Her brain is like a Ferrari in that you can make everything look all right but you won't know until you turn the ignition on whether the engine is going to start," Randazzo said.
Jessica's parents, Lars, 69, and Vivian, 60, were both killed on impact when their car collided with another vehicle driven by Craig Anthony Whitall, 50, who also died.
Whitall, a P-plater, was reportedly driving home from a methadone clinic when the collision occurred.
The coronial investigation into the crash will focus on whether Mr Whitall was under the influence of drugs at the time of the crash.
