Some say yeh, some say nar, i drive past often and the entrance near the petrol station often has large signs saying 'no trespassing' etc, but they never last long.
From what I’ve been told there are two separate land owners, one along the creek don't mind - other does.
All hear say sooo...
One thing i can say for sure is that if you ride from where you park to the track the cops can fine you or take your bike etc I've been riding in there on my pitty and often see cops on bikes but not sure if they are there to check for stolen cars or just to be seen. Never been booked.
