Andrew Delfosse Badgery (Del Badgery) built and flew the first aircraft consucted in Australia and was also the first to fly an aircraft in Tasmania on Sept.10th.1914, Badgery's Creek is named after him, his wife Dorothy (Wall) was the creator of Blinky Bill and their only child Peter, born in 1925 served in the RAAF during WW2, later joining Qantas (DC3), then joining Fiji Airways, he moved back to Australia in the 70s... Why not honour the aviation pioneer and retain Badgery in the airport's name?
Zlin,
I think there might be some challenge to this. John Duigan built and flew the first Australian designed aircraft in 1910.

There is a really good book about Duigan called 'A flying life' by David Crotty.
Perhaps The new airport should be named after him.
