The drivers of two 4WDs recorded driving recklessly on Stockton Dunes last weekend potentially face thousands of dollars in fines and criminal charges if caught, police have warned.
Police confirmed on Wednesday they were analysing social media footage of the vehicles flying several metres through the air as part of their investigation.
In addition to facing dangerous driving charges, the drivers could also be charged under the NSW National Parks and Wildlife Act.
The Worimi Conservation Lands Board of Management and the Worimi Local Aboriginal Land Council also condemned the reckless driving.
Board chairman Jamie Tarrant said the incident was an appalling display of illegal and dangerous driving.
"This type of behaviour is not welcome in the Worimi Conservation Lands. It is unsafe, disrespectful and totally at odds with the kind of experience we welcome visitors to the park to enjoy," he said.
Patrols and security in the park will be stepped up to stamp out any copycat behaviour.
"The board has spent over a decade working to provide a safe and enjoyable experience and a family friendly atmosphere while still providing opportunities for sustainable dune and beach driving," he said.
"Most of our visitors respect the park rules and this beautiful part of the coastline, however unfortunately, this weekend, everyone has been let down by a handful of foolish and irresponsible drivers.
"Fortunately, for these visitors they escaped serious injury despite significant damage to one of the vehicles, however, this could have been a very different story. We have seen many serious accidents due to dangerous and reckless driving in the dunes."
Four Wheel Drive NSW and ACT vice president Shane McClymont said the organisation did not condone reckless driving.
"It goes against our code of conduct that our members follow, and we fully support the Worimi Conservation Lands Board of Management and the NSW National Parks and Wildlife Service in this matter," Mr McClymont said.
All vehicles entering the Worimi Conservation Lands must be registered and display a valid Worimi Conservation Lands beach vehicle permit.
