The body of missing 18-year-old bushwalker Lily Hooper has been found in a remote New South Wales national park more than a week after she set out on her hike.NSW police said in a statement on Thursday: “The body of a woman has been located in bushland following the search for a missing bushwalker in the southern highlands.”The assistant commissioner Joe Cassar later said the initial report from the “thick and dense terrain” where Lily was located was that the teenager had been found alive.However, within 10 minutes a “more accurate account” was relayed to police from SES search volunteers at the scene and it was confirmed Lily was dead.“There’s no playbook to communication,” Cassar told reporters in Moss Vale on Thursday afternoon.Earlier, a police spokesperson had said in a statement “while yet to be formally identified, the body is believed to be that of the 18-year-old woman”. They said a report would be prepared for the coroner.Initially, police media reported a “hiker” had been found after the multi-agency search in the rugged terrain of Nattai national park, about 90km south-west of Sydney.Sign up for the Breaking News Australia emailThe NSW premier, Chris Minns, told parliament Lily had been “found alive” with half a bottle of water.Within minutes, he announced: “I’ve got some terrible news. I apologise … it seems as if the earlier advice was wrong.”“Lily’s body has been found,” the premier said. She’d been found deceased. This is obviously devastating, and I’m profoundly sad for her family and for all those concerned. I apologise.”Minns later said in a statement he received incorrect advice and “genuinely believed” he was sharing good news.
