Parliament grieves for Linda Burney's loss

An emotional Malcolm Turnbull has told Labor MP Linda Burney her parliamentary colleagues grieve with her over the sudden death of her son.

"Linda's loss is unspeakably sad," the prime minister told parliament on Wednesday, adding the worst dread of all parents was the loss of a child.

"She is a strong woman. Stronger because of the love that all of us, the sympathy that all of us, the friendship that all of us share with her at this tragic time."

Binni Kirkbright-Burney, 33, was found dead on Tuesday night at the Burney family home in Sydney.

"I returned to Sydney last night to be with him this one last time," Ms Burney said in a statement, describing her son as a caring and loving man who 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. "

Ms Burney said police had told her there appeared to be no suspicious circumstances, but the cause of her son's death was yet to be determined.

"I don't want to pre-empt subsequent inquiry but we all thought we were getting somewhere. I don't know what life will be like without him."

Labor leader Bill Shorten reiterated the prime minister's remarks, saying losing a child was every parent's nightmare.
