Police have been studying video footage as they try to identify reckless jet-ski rider who rode his craft up the Swallow Rock boat ramp at Grays Point and skidded well into the car park.
NSW Police Force's, Marine Area Command Chief Inspector Joe McNulty said the actions were “just negligent and dangerous”.
“It was travelling at high speed, left the water and travelled up through a car park where there could have been women and kids, packing up after a Sunday boating activity, and dangerously impacting on their lives as well,” he said.
The video, which was posted on Instagram appears to have been taken by another jet ski rider travelling alongside.
Laughter can be heard from a group of people as the jet-ski skids up the car park.
