Luxury camp inside Walls of Jerusalem WHA with heli access

I have been following RiverFly 1864's proposal to build a permanent standing camp on Halls Island, inside the Walls of Jerusalem WHA.
Access will be via helicopter to a new helipad and track to be built just south of Lake Malbena.
The proposal has now been posted on the Federal Environment Department EPBC website, so it must require approval under the EPBC Act 1999.
http://epbcnotices.environment.gov.au/invitations/, number 2018/8177.
They have invited public comment, which closes on 17 April.
Pretty extraordinary that they are able to do this inside the boundary Walls of Jerusalem WHA.
Stage II, according to the proposal, will be a new, walking track to Mount Oana, likewise inside the WHA - at the moment there are not even footpads in this area.
I understand how the original owner was able to get a lease on Halls Island in 1955, and how that lease passed to his daughter.
What I don't understand is how Riverfly 1864 were able to get that lease transferred to them in the last few years. Shouldn't the lease have been transferred to the Government so Halls Island could be incorporated into the Walls of Jersualem National Park?
The proposal is for 30 trips a year - assuming 4 days per trip that essentially puts Halls Island off-limits to the public for 120 days a year.
Aside from that, the precedent for private developments in remove parts of the WHA where there are not even any formed tracks at present, and helicopter access for clients, is an extremely negative development in my view.
I've been visiting Halls Island most years since 1995 - I would be extremely sorry to see it developed as proposed.
Interested to hear people's thoughts on it.
