NSW man charged after crane stunt

A NSW man who was filmed dangling from a 12-storey-high crane has been charged with trespass.

A video has emerged of the 20-year-old walking precariously along a chain strung the length of a crane's arm at a Wollongong construction site about 6.45am on Australia Day.

The man, who wasn't wearing a harness, can be seen wobbling back and forth as he stands on the chain.

The 20-year-old has been charged with trespass and risk safety of another, said a NSW police spokeswoman.
