Superintendent Hawkins said police would continue to be out in force this Labour Day long weekend. "Close to 500 traffic infringement notices have been issued in the past two years in the area with at least three vehicles impounded," he said. "Drone surveillance has revealed drivers are continuing to engage in risky behaviour and police remain committed to following up any reports of dangerous activity which may put other motorists and innocent campers at risk of injury." Queensland Parks and Wildlife Service state compliance manager Michael Devery said rangers regularly monitored visitor behaviour. He said fines were issued for non-compliance, failure to have necessary permits and for environmentally and socially inappropriate behaviour.
