The 29-year-old actress and her family were involved in a fatal crash on Boxing Day, where her parents, Vivian and Lars, were instantly killed.
Her parents were killed on St Stephen's Day when their auto collided with another vehicle.
Annabelle died in hospital three days later, and Jessica had remained in a coma following several surgeries.
Heartbroken relatives of actress Jessica Falkholt made sure she was not alone in hospital while her parents and sister were buried.
Her parents and younger sister - whom Falkholt was in the vehicle with - each died as a result of the accident, as did the other car's driver, Craig Whitall.
Whitall was a habitual traffic offender with more than 60 convictions to his name, according to The Daily Telegraph.
A funeral notice for the ceremony at St Mary's Catholic Church in Concord described the Falkholt family as a "dearly loved and cherished father, mother and sister to Jessica". All three family members were farewelled at a funeral on Wednesday.

Harris rushed for 1,000 yards and 11 TDs as a junior and has won two national titles while at Alabama. He had 63 catches for 967 yards while no other wide receiver caught more than 14 balls.
Paul Ponticello, the brother of Vivian, said he "always thought we would grow old together", according to The Daily Telegraph.
News.com.au report that Mr. Ponticello told the service: "The irony of the tragedy is that Lars was such a careful driver".
"Whenever he'd ask to drive somewhere I'd suggest a time for an average driver and add on some additional time for the "Lars factor" because he was so careful". They are together and always will be.
Her parents, Lars and Vivian, were killed in the crash. You will always be remembered and in our hearts forever.
While the actress is best known for her appearance in long-running soap Home And Away, she enjoyed minor roles in Aussie dramas Underbelly: Badness and Tricky Business.
A Facebook post this morning confirmed that the 29-year-old was expected to make her debut in the movie, which was expected to be released this year.
