A woman has died at a retreat in Victoria and police are investigating if she became unwell after consuming a drink.

Officers are examining whether the drink contained mushrooms, The Age newspaper reports.

The death of the 53-year-old at a retreat in the town of Clunes is being probed by detectives from the Moorabool Crime Investigation Unit.

A spokesperson for Victoria Police said it was believed the Ringwood North woman became ill after ingesting a drink about noon on Saturday.

Two other people were taken to hospital.

The investigation is open and a report will be prepared for the coroner.

The retreat describes itself on social media as an alternative and holistic health service.

A planned event described as “sound healing” was cancelled on Sunday.

On Friday night, the retreat hosted an event with a medium where guests were given a chance to “ask questions of the spirit communicators”.

Clunes is in central Victoria, about 30 kilometres from Ballarat, which has experienced a series of tragic events in 2024.

Since February three local women, Samantha Murphy, Rebecca Young and Hannah McGuire died allegedly at the hands of men.

Miner Kurt Hourigan died in a mine collapse in March and the area experienced bushfires over summer.

The owner of the retreat has been contacted for comment.
