Hi, don't know much about the Bendigo area (I'm in Sydney) In Melbourne, the capital of Victoria (would be a couple of hours drive from Bendigo) there is a small museum at Moorabin Airport and also Point Cook RAAF base (a little South-West of Melbourne CBD) has a museum too, with a single aircraft flying display (the aircraft varies) two or three days a week. Point Cook also will host a weekend airshow on March 1st and 2nd this year - The Centenary of (Australian) Military Aviation. Sorry, best I can do.
