CAMPER vans, four-wheel-drives and trail bikes descended on Broadmeadow's District Park last week to take part in the Unlock Australia meeting.
People who attended the Newcastle rally protested about the inaccessibility of the coastal dunes along Stockton Bight, officially known as the Worimi Conservation Lands.
Protest organisers say between 8000 and 10,000 people attended but police say the number was closer to 2000 people.
Thousands of cars formed a 48-kilometre convoy between Cessnock and Stockton, making their point known to as many possible.
Recent figures have indicated that up to 180,000 people visit the beach each year from the Birubi end, many of them using 4WD vehicles to gain access.
Erosion is a major issue at Stockton, where part of the dunes has been closed by the National Parks and Wildlife Service after storm damage last year.
Four-wheel-drive access to Stockton Beach will be limited until March because of upgrades to the Lavis Lane entrance of the Worimi Conservation Lands.
The $300,000 upgrades include the realignment of Lavis Lane, sealing a section of the road, and improvements to the car park and signage.
