A scuba diver who got separated from his party and ended up stranded 30 miles out at sea recorded what he believed to be his last moments.

In 2016, Jacob Childs faced a number of challenges when diving off the coast of south-east Queensland, Australia.

The diver could see the boat departing as he came out of the water but lost sight of the safety line.

Even though he made every attempt to catch up to the boat, it finally disappeared from view, leaving him stranded for six hours.

Jacob made the decision to record what he thought would be his last moments since he didn’t think the rescue team would be able to find him in the pitch black as the sun started going down.  

In the video, he says: “So that’s it. The sun goes down they won’t do nothing. That’s a wrap on old Jakey.”

The diver said that he ran into problems when he surfaced and saw that the rope had been drawn in.

Shockingly, the captain took off, rather than returning to fetch him, which made things significantly worse for Jacob.

Following the whole ordeal, he told ABC news: “We took a while to anchor up … which left us [with] several people in different states of readiness. I was one of the first to hop in [to the water].

“It was then 15 minutes before the last people hopped in … in which time we were fighting the current the whole way.

“Then we started to descend down the line. One person was up the top, so I went to swap hands and I missed the rope … so I surfaced alongside to the boat.

“There was no tagline out the back for me to grab on to … by the time the skipper had thrown it out I was already past it.”

He told the Express: “It’s a long time to spend by yourself, and it’s a long swim back to shore.

“There’s nothing to judge where you are. All the waves look the same and there’s no land to try and gage yourself against.

“I think they picked me up eight miles from where we were diving.”

Thankfully a massive rescue effort was launched to find him, and at around 5.30 in the evening, an aircraft saw him floating in the sea.

According to Jacob, he “was nice and warm in my wetsuit … I wasn’t overly tired as I was floating.

“I just wanted a drink of water and a cup of tea.”

Sergeant Rob Jorna, the officer in command of the rescue effort, claimed that Jacob’s experience helped the crew locate him.

He said: “He knew what to do, and his level headedness at the time, and he didn’t panic and he did all the right things, and activated his safety equipment which alerted the air observer.”
