Family and friends of the Falkholt family have gathered in Sydney's inner west to farewell Lars, Vivian and Annabelle, who were killed in a horror car crash on Boxing Day.
Three caskets were carried into St Mary's Catholic Church in Concord on Wednesday morning as hundreds of mourners made their way into the church for the funeral service - as former Home and Away actress Jessica remains in a critical condition.
Lars and Vivian Falkholt were killed when their car collided with a 4WD on the NSW South Coast on December 26.
Their daughters, Annabelle, 21, and Jessica, 29, were pulled from the wreckage of the car before it erupted in flames.
Annabelle was flown to Liverpool Hospital in a critical condition but died three days later.
Mourners dressed in black were seen embracing outside before greeting the priest and entering the church.
The deceased trio has been described as the "dearly loved and cherished father, mother and sister to Jessica," in a funeral notice published by Fairfax Media.
"Lars, Vivian and Annabelle will be deeply missed by Vivian's brother Paul Ponticello, his children Paul and Natalie, along with many relatives and friends both near and far," the notice read.
"In Sweden, Lars leaves behind his brothers, sister and extended family."
Vivian had Italian heritage.
Donations to cancer charity Redkite have been requested in lieu of flowers.
Jessica remains in a critical condition at St George Hospital, a hospital spokeswoman said on Tuesday night.
The 29-year-old has undergone several surgeries including the removal of a kidney and part of her skull and is in a coma, News Corp Australia reports.
In recent years Jessica found fame on the small screen as Hope Morrison in Home and Away, with the long-running TV soap paving the way for her feature film debut in the forthcoming supernatural thriller Harmony.
