If the booking system(s) limit the numbers to similar/capped levels there may be no need for prohibitions.
As it stands, our park service 'Leave no Trace' guidelines do indeed make camping on top of Mt Ossa 'doing something wrong'.

All communications, in line with these guidelines, should be aimed at discouragement. Iv'e no reason to suspect they aren't.
If you have been discouraged, what happens next is a choice to take part in neglect, or not.
What has been obvious (for a long time) is a need to sort out toilet issues up there.
We can have a toilet at Pelion pass but it doesn't address any effect of pooing anywhere higher. And given day-walkers to Mt Ossa may not be carrying a trowel etc.
I'd choose a info board and rack at the Pelion Hut toilet offering those waste bags to carry to Kia Ora.. just that..
I'd then not listen to excuses..
We'll pick up our warm dogs poo and carry that a way..
We'll sit on a communal seat, over a (excuse me) festering, fly-blown cess pit..
Some visitors don't understand, in this age, why even an active composting toilet isn't achievable out there. WAG (waste) bags, still early days, it's shaping up as a matter of demographics for the reaction. Some europeans seem to be able to identify what it is without question, while i'm still trying to formulate the latest introductory spiel.
We can have a toilet at Pelion Pass, another in the area. This is the model we can grow with. Choices are made, however some quite subtle. It's time for these things now but what happens as we build up eg. waste and heli services. Being businesses.. always looking for growth and afforded influence. Why on earth would they ever support WAG bags anywhere. As happens, lobby against such things is very much more likely. We could cut in half the necessary toilets and flights for this developed track ingress.. minimising our impact, support a more sustainable waste 'industry' and therefore a proper effort at LNT & sustainable tourism.. or not.
So much bigger than simply supporting/ or not the latest transgression. I don't have any Z packs gear (hear it's pretty good). Easy for me to swap the subject for the eg.Kathmandu / Aldi corporate junket. I suspect support would be more circumspect from some other members here. If the Z packs team take responsibility/ remove the camping references from their vid, cut the place some slack, there is simply no issue left (here).
