Model Annalise Braakensiek, who appeared in shows such as Pizza, has died aged 46.
Media reports claim she was found dead in her Sydney apartment on Sunday afternoon.
Close friends and family became concerned for her wellbeing after she stopped replying to their text messages on Thursday, News Corp reported.
Police rescue and ambulance attended the apartment where they found Ms Braakensiek, 45, deceased.
Braakensiek had fought a public battle with depression for years and was an ambassador for RUOK? Day in 2017. At the time, she said in an interview with The Daily Edition: “It was the … negative reaction people had to me being depressed and falling under the dark cloud.”
She also split from her stockbroker husband Danny Goldberg in April after 16 years together.
There were no suspicious circumstances, police said, and they will prepare a report for the coroner.
Braakensiek appeared as Claudia MacPherson in 15 episodes of SBS comedy Pizza while her other credits included Home & Away, Sleuth 101 and Heartbreak High.
