Brenda Lin was 15 years old and away on a school excursion in New Caledonia when her uncle Robert Xie bludgeoned five members of her family to death in their home in Sydney's north in 2009.
Evidence given by Lin was subjected to non-publication orders throughout Xie's trial.
But now, three days after the 53-year-old was handed five life sentences for the murders, Lin has given her consent to be identified by participating in an interview with Channel Seven's Sunday Night program.
Xie touched Lin inappropriately before the murders, the court heard during Xie's trial.
His assaults escalated when she moved in with Xie and his wife Kathy Lin - who has defended her husband - after her family was killed.
Lin told court that Xie sexually assaulted her regularly until he was arrested and charged with the murders in May 2011.
Prosecutors argued these assaults were one of Xie's motives for killing, as he would have had complete access to Brenda if her family was dead.
A jury last month found Xie guilty of the murders of his brother-in-law Min Lin, 45, Min’s wife Yun Li “Lily” Lin, 43, and their two sons, Henry, 12, and Terry, nine, in the bedrooms of their Epping home. Yun Li’s sister Yun Bin was also murdered.
"It has been seven-and-a-half years since I have lost my family," Lin told the court in her victim impact statement. "That's seven-and-a-half years without a loving mother; seven-and-a-half years without a loving father; seven-and-a-half years without two exuberant brothers, who were my best and closest friends; and seven-and-a-half years without an extremely kind aunt.
"In this time I have finished my HSC, was accepted into uni, got my first part-time job and learnt to drive. But I have achieved all these things without my family beside me."
"I'd give anything to have my family back," she told the Seven Network in the interview, to be screened on Sunday night.
