A FRIEND of the 14-year-old boy who miraculously survived a 30-metre fall in the Blue Mountains has described the horrifying moment the teenager was “swept away” by water and mud.

Hamish Davis, also 14, was hiking Mount Solitary with four of his mates when they took a wrong turn at Korrowall Knife Edge at 3pm on Saturday.

His friend, Lindsay Bath, was just behind him and said “I don’t really trust this” seconds before he slipped and was washed over the edge, about 3pm.

“He was going down really fast and we didn’t get a chance to react. He was behind me. He was the last one and then he just slipped,” Hamish said.

“We were all really worried about him, we couldn’t see him at all.

“We wanted to have a quick look but we didn’t want to go to the edge because there was lots of water and it was really slippery.”

The group have been praised for keeping calm and the quick thinking that followed.

They called Lindsay with a mobile phone — and remarkably he answered despite serious head injuries.

The teen’s first question to his friends was: “Are you all OK?”

“He kept asking us if we were OK the whole time, that’s the type of person he is,” Hamish said.

Hamish also had two spot trackers and a Personal Locator Beacon and pressed the SOS button to raise the alarm.

His father, Andrew Davis, was the emergency contact and was immediately notified.

“There was an international call centre from America that called me and confirmed where they were and what had happened. He kept me on the line while he summoned the emergency workers,” Mr Davis said.

Hamish said they spoke to Lindsay’s father as well and kept Lindsay on the line for an hour, asking him to describe where he was so they could try find him.

A group of people running happened to pass by the group and then helped locate Lindsay while the Blue Mountains Police Rescue Squad and paramedics were en route.

By 6pm, when the difficult weather conditions had cleared and an Ambulance Helicopter winched Lindsay out of the area and took him to Sydney Children’s Hospital Randwick where he remains in a stable condition today.

“It’s incredible the lack of injuries he got after that fall, it looked like he took quite a fall ... I think he was really lucky,” Hamish said, saying they planned to go visit him in hospital.

Hamish’s dad said he was incredibly proud of how his son and friends — all experienced bush walkers — reacted.

“I’m very proud of him he has handled himself commendably in a difficult situation,” Mr Davis said.

“He has done everything he should have in the right way and proved that he is a capable leader.

“If they didn’t have the beacon, and if they didn’t know what to do, it obviously could have been a lot worse.”

The father and son said they couldn’t be more thankful to the emergency workers for their major rescue effort in the difficult weather conditions.

“The search and rescue people, helicopter people and police rescue people were really awesome,” Hamish said.

Lindsay’s dad, Andrew Bath, said his son had been through surgery “and will be fine”.

“He had a nasty gash at the back of his head and a sprained ankle, but he’s going to be OK,” he said.

He said the boys had all been scouts together for a really long time and were “well trained” in how to prepare for things going wrong in the bush.

“I’m very proud of my son and enormously grateful to the rescue team,” he said.

He said his son told him he was lying on mud when he fell.

They also said it highlighted just how important it was to have a beacon when walking in remote areas.

“The boys were three to four hours away from foot help. Hiking was the only way, other than the helicopter, in or out. (Having the beacon) very much expedited that process,” Mr Davis said.
