No one is saying that thee should be no change. The NT has changed a lot since I first started visiting their properties in the 1970s, mostly for the best, but in recent years they have begun to think they are the nation's conscience and as soon as one or two people get some publicity for themselves saying something is bad for us, whether sugar, palm oil or any other cause, especially if supported by a popular environmentalist, they immediately jump on the bandwagon.
Now if they were truly concerned about all these matters they would ban all visitors who arrived at their properties by private car. Only those arriving by public transport, or under their own power, bike or foot. Even electric vehicles sgould be banned because of the enormous damaging imprint of making the batteries for them and disposing of them afterwards.
But they won't do that will they? Most of their properties are in rural areas, a long way from good transport links, even if the NT ran their own shuttle buses and many people who would drive to a stately home or remote area of countryside, and get their in 30 minutes or an hour will not spend three hours and all the hassle of getting there by public transport and then as long or longer trying to get home again
