Christine Formosa Rakic was found dead in a Rooty Hill home on Tuesday night in the latest of a spate of alleged domestic violence-related deaths across Sydney in recent weeks.
Her ex-husband, Dusan Rakic, is due to face a local court via video link from his hospital bed on Friday morning on charges of murder, breaching bail and contravening an apprehended violence order.
The 50-year-old had been in an induced coma after suffering critical wounds to his throat and arms after allegedly attacking Ms Rakic on Tuesday.
Police previously said there had been "some interactions" between officers and Rakic.
Mrs Rakic's death was something her family never thought it would have to experience, her niece Jacinta said
"Our family is currently going through a tremendous amount of pain, hurt, shock and disbelief," she said on Thursday.
"Christine was a caring and humorous person, she had so much love to give, she loved animals, spending time around her family and the light of her life were her children and grandson."
She made the comments on an online fundraiser for the 53-year-old's funeral.
Donations had reached 60 per cent of the $15,000 goal by late on Friday morning.
"We want to thank everyone who has reached out to the family to share their condolences and extended love," Jacinta said.
Rakic remains under police guard in hospital and will move into a prison upon discharge from Westmead Hospital, unless he is granted bail.
