maps-of-all-beaches---driving-and-access-areas

Vehicles are permitted to access beaches:

  • to launch or retrieve boats in designated boat launch areas, provided they take the shortest practical route
  • to drive along the foreshore in beach driving areas ONLY – see above  maps showing accessways and driving zones on the beach
  • for emergency purposes.

       Note: two-wheeled motorbikes are banned from all beach areas.

Any vehicle brought onto the beach must:

  • access the beach via an authorised vehicle accessway (as long as 10km/h isn’t exceeded on these accessways)
  • not be parked in a way that blocks access for other beach users
  • be driven in a safe and careful manner (no more than 20km/h, in permitted beach driving areas ONLY)
  • not be repeatedly driven back and forth over the same stretch of wet sand (as this can damage shellfish beds)
  • not be driven onto dune areas as they are fragile and contain breeding birds and erosion control plants.
