NSW skydiver unharmed after tree crash

A skydiver has escaped injury after reports he crashed into a tree near a busy highway on Sydney's outskirts.

Paramedics were called to the scene near Picton shortly before 11am on Wednesday by someone driving on the Hume Highway but were not required to treat anyone, a NSW Ambulance spokesman said.

A spokeswoman from Sydney Skydivers Drop Zone would not confirm where the man landed, saying he walked away unharmed.

"We don't wish to discuss it, there was no ambulance or police called," she told AAP.
