One is the not-for-profit History Museum, the other is the Transfield-owned Range Museum, which has an entry fee.
There are several aircraft on outside display including a Canberra, Meteor and Jindivik. There are also examples of various rockets and missiles, including the large Blue Steel that was carried by the British Vulcan bomber.
There are some good reviews on TripAdvisor, as always.
