Kiama mayor Brian Petschler has condemned footage showing a young man jumping off a cliff into the South Coast town’s famous blowhole.
‘‘This kind of behaviour is extremely irresponsible. The signs warn people who choose to engage in dangerous recreational activities that they do so at their own risk,’’ he said.
‘‘Unfortunately you can’t stop stupidity.’’
The video obtained by AAP, now deleted from Facebook, shows onlookers screaming as the youth jumps from the rocks into the surging water below.
Police told AAP that diving off the cliffs was dangerous and nearby signs clearly forbade it.
A 60-year-old man died in 2014 when he was swept off the rocks while fishing near the blowhole.
