And it is not "just" the individual HLS's going. It will be their associated instrument approaches as well. Westmead has 3, 2 GNSS 1 NDB. Merriwa has a GNSS, it's on the list, so is Mossman Hospital and Tully Hospital.
Sure you might be able to find an accident scene and get down in bad weather, but if the hospital approach no longer exists, how do you find the HLS to offload your patient?
