Australia

From my reading it's going to be the same campgrounds that already exist, but now with a commercial operator being able to book a proportion of the sites before the public can. I don't know if they will physically separate the commercially booked sites but at this point I have seen no mention of expanding or creating campgrounds for this purpose.

I am ideologically against letting commercial operators into this field - I accept the reality that camping fees in national parks are a necessary evil to help with provision of services and reduce false bookings, but I think if such fees are going to exist the money should go directly to Parks rather than have the majority go to a private company. Commercial camping operations should be operating on private land rather than public - that way public access to public land is not reduced and the public gets limited access to land they would not otherwise get to (the camping might even help fund preservation of said private land).
