A 19-year-old woman has died after taking a unidentified substance at the FOMO music festival in western Sydney. The teenager, from the central coast, was attending the festival at Parramatta Park when she collapsed about 6:00pm yesterday. A NSW Ambulance spokesman said the reveller was presented to the medical centre at the festival site, appearing to have a reaction to drugs. Paramedics treated her at the scene and in the ambulance on the way to Westmead Hospital where she later died. Police believed the woman took an “unidentified substance” but were still confirming the circumstances behind her death. She is the fifth young person to die at a music festival over 2018/2019 festival season. She is yet to be identified. Her family was notified of her death. An estimated 11,387 attended FOMO — headlined by US singer Nicky Minaj — with officers searching 146 people and finding 54 of them with drugs. Police said 24 were ejected, mostly for intoxication, while 28 were refused entry. The police are preparing a report for the coroner. The organisers behind FOMO festival were contacted for comment. The woman’s death comes as debate in New South Wales rages over the benefits of pill-testing at festivals.
