Frightening footage of 'dumb' thrillseekers
Authorities have appealed to young thrillseekers not to copy people seen on social media, throwing themselves off Sydney's North Head.
They are tied to ropes with suspect anchors, risking certain death if they crash onto rocks 70 metres below.
Climbers call it 'The Fear': Sheer cliffs, 100 metres high at Sydney's North Head, but it plays centre stage in an act of extreme recklessness.
A rope swinger dangles above the drop, then plunges 70 metres in free fall before the rope hurtles him across the cliff face, underneath an overhang - before returning in a dangerous pendulum, swinging backwards and forwards.
It's illegal, but the popular rock climbing site is rated medium difficulty.
Police say it isn't the experienced, well equipped thrillseekers they are really worried about, it's the amateur copycats.
"It's frightening, and if it does so it will be catastrophic," Inspector Nigel Taylor said.
"These people... make it look easy on the video, but I can assure it is an extremely dangerous location."
Not just swinging on a rope, even being a spectator is dangerous, on rock edges considered unstable, and in strong, unpredictable winds.
It does not stop the audience getting close.
National Parks is appealing for information to identify rope swingers. They are risking a fine of $300.
