Anyway.. Walkers are identified on buying a parks permit/pass aren't they? Maybe their permit should be forfeit if they don't take the booking system seriously?

Admittedly already starting down that path, needing at least someone checking off permits, against bookings. Maybe a 'boothy' at the track-heads, on random days.
