Apart from all the details questioned above, it's great to see a non-aviation operator has thought about using private charter for the snow season. I hope it works out for them, and we see this happen more often!
Don't be so critical everyone. I'm sure CASA will be approving this operation before it happens, and bring many jobs back into the industry for pilots, cabin crew, engineers, ground staff, and check-in crew. It's must be better than be an out-of-work pilot driving a BUS from Adelaide to Wangaratta.
Hope it also makes Wangaratta a better airport, as it is under utilised. Flown there a few times, and always thought it could handle bigger ops.
Cheers KP
