Charlotte Dawson has been found dead at her apartment at the age of 47.
It is believed the Australia's Next Top Model judge was found by her security guard. Suspicions were aroused when she failed to show up for a lunch date with a friend.
In a statement to news.com.au, a police spokesperson said: "About 11am police from the Kings Cross local area command were called to Cowper Wharf Road after the body of a woman had been located in a unit.
"No suspicious circumstances at this stage and a report is being prepared for the coroner."
Born in New Zealand, Dawson moved to New York at 16. She later relocated to Australia where she presented various fashion segments and a show called Runway to L.A.
The former model has battled with depression for many years and was hospitalized in 2012 after being targeted by Twitter trolls.
