URGENT SEARCH UPDATE: The search for missing 18-year-old Lily Hooper has taken a new turn as police continue scouring Nattai National Park and say they remain “very hopeful” of finding her. The experienced hiker vanished while exploring the rugged area alone — and a new detail from the search operation is now giving investigators fresh hope…
In the rugged sandstone country of New South Wales’ Southern Highlands, a young woman set out alone on a midweek morning in August 2026 and simply vanished. Lily Hooper, 18, left her family’s home on Burragorang Road in Oakdale around 8 a.m. on Wednesday, 12 August. She told relatives she was heading into Nattai National Park for a hike on the Bonnum Pic Walking Trail. She kept them updated by text message through the morning. Then the messages stopped. By evening she had not returned. By 11 p.m. her car had been found parked near the trailhead on Wanganderry Road. By nightfall a multi-agency search was under way. As of Saturday, 15 August — the fourth day of the operation — Lily Hooper remains missing.
Police and family have described her as an experienced bushwalker. She is also a dedicated martial artist who had only recently returned from a Muay Thai training camp in Thailand. Her gym, the Bujutsu Martial Arts and Fitness Centre in Smeaton Grange, posted a public appeal calling her “one tough girl” and expressing confidence that if anyone could survive a hiking mishap, it would be Lily. That combination of fitness, outdoor experience and youth has kept searchers hopeful even as the hours stretch into days in difficult terrain.
Detective Inspector Benjamin Bowles of the Hume Police District has repeatedly stressed that there is no information suggesting foul play. “We don’t have any information to suggest that this is anything other than an overdue hiker,” he said. Authorities believe Lily reached the summit of Bonnum Pic by mid-morning on Wednesday. After that, contact ceased. The last messages she sent to family members — the precise content of which has not been released publicly — are now among the few pieces of contemporaneous evidence investigators have about her state of mind and location in the hours before silence fell.
Nattai National Park forms part of the Greater Blue Mountains World Heritage Area. It is a landscape of deep gorges, towering sandstone cliffs and dense eucalypt forest. The Bonnum Pic trail is no casual day walk. AllTrails and bushwalking guides rate it strenuous to very challenging: roughly 15–16 kilometres return, with significant elevation change, sections of overgrown track, rock scrambling and, near the final ridge, exposed sections that some experienced walkers describe as requiring a rope for safety. The route follows a dramatic knife-edge ridgeline that juts into the Wollondilly Valley, offering spectacular views but also demanding reliable navigation skills, especially where post-fire regrowth has obscured the path. Water sources are limited; the walk is best attempted in cooler months. Lily was last seen wearing a shirt and shorts. Police have been unable to confirm exactly what supplies, clothing or emergency equipment she carried.
Her vehicle was located near the start of the trail late on Wednesday night after family members reported her overdue. A command post was established. Searchers from NSW Police, Police Rescue, the State Emergency Service, Fire and Rescue NSW, NSW Ambulance and, later, Australian Defence Force personnel began combing the area. Drones, an ambulance helicopter, PolAir assets, trail-bike riders and ground teams have all been deployed. Family members have joined the effort on the ground. Overnight operations continued where safety allowed; fresh teams arrived at 7 a.m. on Saturday. Temperatures overnight have dropped below five degrees Celsius in places. The terrain is described by police as “fairly rugged” and “quite extensive and rough bushland.”
Premier Chris Minns has publicly expressed solidarity with the family. “Our heart goes out to that young walker’s family,” he said. “We know this must be heartbreaking and incredibly anxious. I’m praying for good news.” Detective Inspector Bowles has echoed that cautious optimism, noting Lily’s experience and the presence of water sources in the broader area, while acknowledging that exact supplies remain unconfirmed. “We are still hopeful that we will be able to locate her safe and sound.”
Lily Hooper is described as Caucasian in appearance, approximately 175 centimetres tall, of slim build, with long blonde hair and blue eyes. She turned 18 in December 2025 and is a recent graduate of Campbelltown Performing Arts High School. Social media posts and family statements paint a picture of a close-knit household; her parents, Kirrily and Jim Hooper, have been described by relatives as “not coping very well.” An aunt, Sheridan Munro, posted publicly that the family was “desperately trying to find her” and praised the emergency crews working around the clock. An uncle, Trent Brideson, told media the family had received no significant new information in the early stages of the search.
The decision to hike alone is not unusual for experienced walkers, yet it carries inherent risks. Police have used the case to remind the public of basic safety practices: lodge a trip intention plan with National Parks where possible, carry adequate water, food, warm clothing and an emergency beacon or satellite communicator, and ensure someone knows the planned route and expected return time. Lily had informed family of her plans but did not, according to police, lodge a formal trip plan with park authorities.
Search coordinators have focused initially on the eight-kilometre (one-way) Bonnum Pic trail and surrounding ridges and gullies. The summit itself is a narrow, exposed feature. Reaching it involves scrambling across rock domes and, for those who continue to the very end of the ridge, negotiating a steep, exposed section sometimes called the “slide of death.” Whether Lily turned back after the summit, continued further, or left the marked route for any reason remains unknown. The last messages she sent — the “four messages before silence” of the title that has circulated in early reporting — are understood to have been sent while she was still on the trail and in contact. Once those messages stopped, and once she failed to respond to attempts to reach her that evening, the window of communication closed.
In missing-person cases involving wilderness, the first 48 to 72 hours are often regarded as critical. After that, the combination of exposure, limited food and water, and the physical demands of the terrain can rapidly reduce survival odds, even for fit young adults. Night-time temperatures, possible injury from a fall on rocky ground, disorientation in dense scrub, or simply becoming overdue and unable to retrace steps are among the scenarios searchers must consider. At the same time, there are documented cases of experienced hikers surviving several days in Australian bushland by finding water, sheltering under rock overhangs and remaining relatively still to conserve energy.
As of the morning of Saturday 15 August, no further signs of Lily — clothing, equipment, footprints beyond the initial inquiries, or other physical evidence — had been publicly reported. The search continues with specialist Police Rescue coordinators directing air and ground assets. Public appeals have been issued for anyone who walked the Bonnum Pic trail on Wednesday, or who has any information about Lily’s movements, to contact Moss Vale Police Station on (02) 4869 7899 or Crime Stoppers on 1800 333 000.

The story of Lily Hooper is still unfolding in real time. An 18-year-old who left home on an ordinary Wednesday morning with a plan, a phone and the confidence of an experienced walker has become the focus of one of the most intensive multi-agency searches currently under way in New South Wales. The messages she sent that morning are the last direct words her family received. In the silence that followed, those texts have taken on the weight of potential clues: timestamps that may help reconstruct her progress toward the summit, tone that may indicate whether she was still progressing normally or beginning to encounter difficulty, and content that may reveal her intentions for the remainder of the day.
Police remain hopeful. Family and friends remain desperate for news. Searchers continue to move through the sandstone ridges and dense bush of Nattai National Park. Somewhere in that landscape, or along the routes leading out of it, lies the answer to what happened after the final message was sent and the silence began.
Until that answer is found, the focus stays on the search: methodical, multi-layered, and still conducted in the belief that Lily Hooper can be located alive. The rugged beauty of Bonnum Pic has drawn many walkers before her. For one young woman who set out alone on 12 August 2026, it has become the centre of a community’s hope and a family’s ordeal. The last messages she wrote are now part of the public record of her journey — brief digital traces of a life that, until that morning, had been full of movement, training, travel and connection. Those traces, and the silence that followed them, continue to guide the effort to bring her home.
