National and State parks need funding from somewhere. I agree that Private operators should not act as middlemen in building “Resorts” or “Glamp Sites”, where they can funnel off the bulk of the profits and only leave a pittance for Park maintenance.
Any “improvements” need to be designed, developed, deployed and managed by the Public Sector for the public benefit.
Natural environments do need to be maintained. Whether it is by Traditional Owners, Western-style Park Rangers, Primary Industry producers or just local concerned citizens; they need to be audited and managed for the benefit of the whole community, national interest and future wellbeing and prosperity.
