Jack. Avalon east is FREE to land at. They will once again have 2 strips available and ATC RFF. What else do you want for free??
The main Rwy 18/36 at YMAV will be way too busy with Airshow traffic and Jetstar RPT movements to let you in there with your bug smasher...fair enough?
Do you have any idea how much people like M Hall and HARS charge to appear?? Thought not.
The guys running the show do work closely with most large Airshows around the world and attend the same shows in a working capacity to both help and learn.
Maybe you could do a better job with the limited budget they have but I doubt it....
