I'm at a loss to understand how a crowd like Wagners could spend so much on a very large private airport, and yet only have one runway? Does the wind only blow in one direction in Toowoomba??
From a jet ops perspective, Cooly, Sunshine Coast, Cairns, Townsville, Alice, Ayers Rock, Kalgoorlie, Karratha, Paraburdoo, Newman, etc. etc. all seem to cope well with only one runway.
