Lewis,
As far as I'm aware, the only areas in the Gramps where climbing is prohibited is in reference areas where general public access is prohibited. The only recognised climbing area affected is the left end of Liomin Castle.
There are examples of climbing prohibition in other Victorian National Parks, the most important being Tongue Point at Wilsons Prom. While not a National Park, the prohbition on climbing at Hanging Rock is also a major concern as this was one of the birth places of Victorian climbing.
