HEARTBREAKING UPDATE: The family of missing Sydney teen Lily Hooper, 18, has broken their silence as the search continues after she vanished without a trace in Nattai National Park. New details have now emerged about her disappearance — and the latest information has given loved ones a renewed reason to keep hoping…
The family of 18-year-old Lily Hooper is living through every parent’s and relative’s nightmare. On Wednesday morning, 12 August 2026, the experienced young bushwalker left the family home on Burragorang Road in Oakdale, in Sydney’s south-west, telling loved ones she was heading out for a hike in Nattai National Park. She kept them updated with messages throughout the morning. Then the messages stopped. She did not return that evening. By late night her car had been found at the trailhead. By the time her uncle spoke to media on Friday afternoon, more than 48 hours had passed with no further sign of her. As the search entered its fourth day on Saturday, 15 August, the family’s public comments painted a picture of raw anxiety, fragile hope and a desperate desire for any scrap of information that might bring Lily home.
Lily’s uncle, Trent Brideson, told the Daily Mail on Friday that the family had been given no significant new information. He described her parents, Kirrily and Jim Hooper, as “understandably not coping very well.” The understatement carried the weight of days spent waiting by phones, scanning updates and trying to hold onto the belief that their fit, capable daughter could still be found alive in the rugged Southern Highlands bushland. Lily’s aunt, Sheridan Munro, posted on Facebook: “My beautiful niece Lily Hooper went on a hike in the Southern Highlands and hasn’t returned. We are desperately trying to find her.” In a later update she added that emergency crews had been “working around the clock” and were “incredible,” while confirming the painful reality that Lily still had not been located. “Praying,” she wrote.
Those brief public statements have become the family’s voice in a story that has rapidly drawn statewide attention. Relatives have joined search efforts alongside police, SES volunteers, firefighters and other agencies in some accounts, though Brideson earlier indicated that only authorised personnel were permitted into certain active search zones tracking Lily’s last known movements. The tension between wanting to be physically present in the search and being forced to wait for official updates is a common and agonising feature of missing-person cases in remote terrain.
Lily herself is described by those who know her as far more than a typical teenager heading out for a walk. She is an experienced bushwalker. She is also a dedicated martial artist. Only weeks earlier she had returned from a Muay Thai training camp in Thailand, which she had described on social media as “epic.” Her gym, the Bujutsu Martial Arts and Fitness Centre in Smeaton Grange, posted a public appeal calling her “one tough girl” and stating that if anyone could survive a hiking accident, it would be Lily. Friends and training partners have echoed that assessment of her fitness, resilience and outdoor capability. She is a recent graduate of Campbelltown Performing Arts High School, turned 18 in December 2025, and comes from a close-knit family that regularly shared photos of gatherings with sisters and cousins.
The timeline of her disappearance is now well established. Around 8 a.m. on Wednesday she left home with the intention of hiking the Bonnum Pic Walking Trail in Nattai National Park, roughly 60 to 80 kilometres from her Oakdale base and about 90 minutes’ drive from central Sydney. She remained in phone contact with family members during the morning, sending messages that indicated she was progressing along the trail. Police inquiries suggest she reached the summit of Bonnum Pic by mid-morning. After that, contact ceased. When she failed to return by approximately 10 p.m., the family reported her missing. Officers from the Hume Police District located her vehicle parked on Wanganderry Road near the start of the trail around 11 p.m. A command post was established and a multi-agency search began almost immediately.
Detective Inspector Benjamin Bowles of the Hume Police District has been the primary public face of the investigation. He has repeatedly described Lily as an experienced bushwalker and emphasised that there is no information pointing to foul play. “We don’t have any information to suggest that this is anything other than an overdue hiker,” he has said. At the same time he has acknowledged the seriousness of the situation. “We have not been able to fully confirm what supplies [Lily] had with her at the time, but we are still hopeful that we will be able to locate her safe and sound.” Police have been unable to determine exactly what clothing, food, water or emergency equipment she carried beyond the shirt and shorts she was last seen wearing. Overnight temperatures in the area have dropped below five degrees Celsius in places, adding urgency to the search.
The Bonnum Pic trail itself is no casual outing. Guides rate it strenuous to very challenging: approximately 15–16 kilometres return, involving fire trails, overgrown sections, rock scrambling, navigation across exposed sandstone domes and, near the final ridge, steep and potentially hazardous terrain that some experienced walkers advise treating with a rope. The landscape is part of the Greater Blue Mountains World Heritage Area — deep gorges, towering cliffs and dense eucalypt forest. Post-fire regrowth has made parts of the route difficult to follow. Water sources are limited. It is a walk that rewards experienced walkers with spectacular views over the Wollondilly Valley but demands self-reliance, good navigation skills and appropriate preparation. Police have used the case to remind the public of basic safety measures: tell someone your exact plans, carry adequate supplies, consider an emergency beacon or satellite communicator, and lodge a trip intention form with National Parks where possible. Lily had informed family of her intentions but did not, according to police, lodge a formal plan with park authorities.
As the days have lengthened, the search has expanded. Local police were joined by regional Police Rescue, NSW Ambulance, Fire and Rescue NSW, the State Emergency Service and members of Lily’s family. Drones, an ambulance helicopter, PolAir assets, Rural Fire Service support and Volunteer Rescue Association members have all been involved. Australian Defence Force personnel joined the effort on Friday. Specialist Police Rescue coordinators have directed operations that include trail-bike riders and ground teams moving through “fairly rugged” and “quite extensive and rough bushland.” Search activity continued overnight where conditions allowed; fresh teams arrived at 7 a.m. on Saturday. By then the operation had entered its fourth day with no public report of further physical evidence — no discarded clothing, equipment or confirmed sightings beyond the car and the mid-morning summit assessment.
NSW Premier Chris Minns has publicly expressed solidarity. “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.” Those words have been echoed by many following the case. For the Hooper family the anxiety is not abstract. It is the silence after the last message, the empty place at the table, the knowledge that their daughter or niece is somewhere in that dense, challenging country and that every hour matters.
New details that have emerged since the initial disappearance have mostly refined rather than transformed the picture. The confirmation that Lily reached the summit mid-morning has helped focus search efforts on the upper sections of the trail and surrounding ridges and gullies. The involvement of the ADF and the sustained overnight capability signal the seriousness with which authorities are treating the case. Family members’ willingness to speak publicly, even briefly, has humanised the statistics and underscored the emotional toll. Reports that relatives have been able to participate in aspects of the search, while others remain restricted from certain zones, illustrate the practical and emotional complexity of large-scale wilderness operations.
Lily is described as Caucasian in appearance, about 175 centimetres tall, of slim build, with long blonde hair and blue eyes. Anyone who walked the Bonnum Pic trail on Wednesday, or who has any information about her movements or whereabouts, is urged to contact Moss Vale Police Station on (02) 4869 7899 or Crime Stoppers on 1800 333 000.
For Kirrily and Jim Hooper, for Trent Brideson, Sheridan Munro and the wider circle of relatives and friends, the days since Wednesday morning have been measured in unanswered messages, briefings that contain no breakthrough, and the constant effort to remain hopeful while confronting the realities of rugged terrain, limited supplies and the passage of time. Lily left home as a capable, fit young woman planning a solo hike she was experienced enough to undertake. She kept her family updated until the point when she could no longer do so. In the silence that followed, her family has chosen to speak — not with speculation or accusations, but with the simple, devastating truth that they are desperate to find her and that the waiting is almost unbearable.
The search continues. Fresh teams are on the ground. Air assets are still scanning the ridges and valleys of Nattai National Park. Police remain hopeful. The family remains suspended between hope and dread. And the young woman at the centre of it all — the experienced hiker, the Muay Thai trainee, the daughter and niece whose last messages still linger on family phones — is still missing without a trace. Every new detail that emerges is scrutinised for meaning. Every public statement from relatives is a reminder that behind the operational briefings and the maps of search grids there is a family that simply wants Lily home.
