Hiker to be honoured as family suggests 'Lily's Law'

A teenage hiker missing for more than a week before being found dead will receive a special honour from her state, as her father highlights the dangers of the bush.

Lily Hooper, 18, was found dead on Thursday, eight days after leaving her home in Oakdale, southwest of Sydney, for a day-long hike in Nattai National Park.

Her father has asked the government to consider flying the flag on Sydney Harbour Bridge, where Ms Hooper worked as a tour guide, at half-mast.

NSW Premier Chris Minns confirmed he was in contact with the family and the state was planning to honour the teenager.

"I want to talk with them and work on it together, but we'll do something special for Lily," he said.

"In recognition of her life, but also in recognition of the fact … Lily was doing everything right, getting out into public, getting out into the wilderness, seeing nature, living her best life."

A park in her local area hosted an array of purple candles and flowers in Ms Hooper's honour over the weekend.

Jim Hooper said he wanted his daughter's death to help raise bush safety awareness.

"It'd be good if there was a legacy that was left like a Skye's Law, Jack's Law ... Lily's Law," he told Seven on Sunday.

"That's about the awareness of going out in the bush with (radio beacons), tracker devices, Garmin, Navman type devices... the bush can swallow you up."

Geospatial scientist Krystal Dacey told AAP disappearances were a risk for hikers of all experience levels.

"From my work on lost people, I can say that high levels of wilderness experience does not prevent a person from getting lost," she said.

Ms Dacey said traditional bush safety recommendations remained relevant - including the use of personal locators.

Considering navigation itself as a risk could also help prevent hikers from becoming lost, she said.
