Here's my 2 cents worth, happy to be corrected.
The owner of Gnaraloo is in the process of upgrading the accomodation at the Homestead compound, so I assume the contestants etc will be based there.
3 mile camp is already a cess pit, with the 'Piss' fence, food scraps and litter left by the hundreds of visitors there.
The reef and track at tombies have already been severely degraded by over use.
The air strip is already regularly used by travelling surfers
I assume the contest will be in winter as this is when conditions are best for surfing tombstones.
Unfortunately if you're trying to save Gnaraloo you're about 20 years too late


Try further north, there are still a few special spots
