Labor frontbencher Linda Burney will take leave from Parliament after her 33-year-old son was found dead in the family home on Tuesday night.

In a statement, Ms Burney asked for privacy "in this dire, grief-stricken time" and said NSW Police had advised there were no suspicious circumstances surrounding the death.

"I wish to advise that my beloved son, Binni Kirkbright-Burney was found dead last night at our family home in Sydney," she said, describing him as a "caring and loving man".

"I returned to Sydney last night to be with him this one last time ... He has struggled with mental health and with addiction. He tried so hard to conquer his demons, as I and my family have tried so hard to support him in every way we could.
