"If the authorities had done their jobs the little girl would still have been alive today. Bail did not serve us this time."
It is alleged in documents from Katoomba Local Court that the man, who also cannot be named, repeatedly abused Family and Community Service caseworkers who were trying to protect his children.
"I'm going to f***ing cut yours and your children's heads open," he allegedly told one caseworker, who he bombarded with 200 abusive texts over two weeks.
He told another: "I'm going to split you in half."
The man, who lives in hotels around Sydney and drives a Mercedes, also boasted that he was "the man bikies fear" after being arrested alongside notorious Hells Angels boss Felix Lyle.
"Bring an extinguisher, you're dealing with fire," he told a caseworker, according to court documents. On Friday, he shouted "Let me see my daughter one more time" as he cried in the dock at Blacktown Local Court.
"I love you, Daddy, I love you, Daddy. Please say it one more time," the man shouted.
"Let me see my daughter one more time."
He was appearing in court on firearm offences after allegedly stashing the gun in the house where the girl lived with her mother and three brothers. All were home when she was shot.
The man's lawyer William Barber told the court his client was "losing his mind" and was "very highly traumatised".
He has been charged with possessing the unauthorised and unregistered gun and breaching an AVO. The charges were adjourned to November 3.
He has not been charged over his daughter's death.
Heard sobbing over her dead body on the night of the tragedy, his ex-wife screamed "I hate you, I hate you" and "Rot in hell".
The court was told the father has "extreme issues re: grief".
He was arrested seven times over 12 months in 2015 and 2016 on 20 charges including drink-driving with his children in the car, biting a female police officer on the hand and being caught speeding with drugs in his car.
The Lebanese-born man is due to appear in the NSW District Court after pleading guilty to his role in a $460,000 mortgage fraud. He was arrested as part of Strike Force Apia which also netted Felix Lyle, currently in Villawood Detention Centre where he is fighting deportation to New Zealand.
He is also due to appear at Downing Centre Local Court on September 28, for participating in a criminal group, in criminal activity and supplying prohibited drugs.
