Australian gold medallist Chantelle Newbery says she tried drugs around the time her mum lost her battle with breast cancer.

Australian Olympic diver Chantelle Newbery has spoken about taking drugs after losing her mum to breast cancer.

The Queenslander won Australia’s first Olympic diving gold medal since 1924 in the women’s 10m platform in Athens in 2004.

The 37-year-old pleaded guilty to possession of dangerous drugs and failing to properly dispose of syringes earlier this month. She was placed on a drug diversion program and no conviction was recorded.

The mother of two said she resorted to trying drugs – on and off – around the time of her mother’s death 18 months ago.

“I have experimented with a couple of things but I wouldn’t say I was a drug user,” Newbery told the Nine Network.

“On and off, perhaps every now and then, since then but there’s been no period of time where I have been using drugs or anything like that.”

Newbery said her experience with drugs was that “it doesn’t help” and it was behind her now.

She said her mother spent her final year living with her.

“Mum fought a pretty good fight, she was diagnosed with breast cancer three years before she passed away and she lived with me in the final year and she passed away in our home,” she said.

Newbery, who revealed in 2009 that she suffered depression, said while she hoped to work with divers in the future, her main priority was being a mother to her two sons.

“At the moment I just want to spend time just being a mum.”
