Matt Trigg, 20, was going for a leisurely jog at the remote Green Pools about four kilometres from the Cape Bridgewater car park three weeks ago.

"My girlfriend and I decided to go for a holiday before the Melbourne lockdown restrictions came in," Mr Trigg said.

The couple decided to head along the Great Ocean Road and spent time in Portland.

On the morning of the incident, Mr Trigg, who was training for a half marathon decided to take in the sights at Cape Bridgewater.

"I saw some of the rockpools down below and I decided to go for a swim," Mr Trigg said.

Unfortunately, that was a decision he would regret.

"Some of the rock gave way and I fell down about six to 10 metres," Mr Trigg said.

He lost consciousness for what he believes may have been about 30 minutes.

When he awoke his first thought was to try and call his girlfriend to see if she could help.

He said he was in a lot of pain and was finding it very difficult to walk.

However, Mr Trigg had no reception on his mobile phone. That's when he made the decision to call Triple-0.

Mr Trigg was rescued by Warnambool's HEMS4 rescue helicopter and flown to the Royal Melbourne Hospital.

He had to be winched to safety due to the rough terrain making it a difficult spot to access.

He broke his pelvis in two places, broke a bone in his lower back, broke his jaw in four spots, fractured and dislocated his wrist and sprained his ankle.

Despite this, Mr Trigg knows he is lucky to be alive.

In the hours after the accident, he feared he may never walk again. "It could have been much worse and it was lucky I took my phone," Mr Trigg said.

However, the university student is slowly recovering and already plans to enter another half marathon when he's up to it. "I want to get back to jogging - I really miss it," he said.

Mr Trigg is also keen to return to the south-west.

"Portland is a beautiful place," he said. "We saw whales and seals - we will go back there for sure."

Mr Trigg thanked everyone who helped ensure he got to the hospital in a timely manner.

"Everyone was great - they were all so nice," he said.

The HEMS4 rescue helicopter performed six winch rescues in a six-week period, including Mr Trigg's.

Air Ambulance paramedics are specially trained to perform advanced treatments in challenging environments.
