boat access is minimal there... unless you have a less than 4mtr tinnie. The ramp is a mud slide into a very tidal creek..
The sandflies will carry you away at that time of the year....... seriously ...
Maybe a better option would be Middle Creek. better ramp and access.
These two areas are quite popular though. I would not leave my boat in the water at either location....
There is another option of camping at Pancake Creek, you'll have to get there by boat though. Two ways........ but the only safe way ( for your vehicle ) is to travel via 1770.... launch boat at 1770 and head about 25k's to Bustard Head and then into the creek. Great camping spots just inside and quick access to Outter, Middle and Inner rocks, as well as Pancake Bomie Reef and further afield. This will require a little planning though.
If you can, camp at 1770 or Agnes Water, for the best offshore access, security and infrastructure.
