How about a visit to the Australian National Aviation Museum at Moorabbin Airport; with one of the most important collections of aircraft and engines in Australia this is a fantastic place for those interested in aviation history and technology, and a great place for kids and adults alike to wander around and even look inside a number of aircraft.
Some examples of the collection include a Mirage jet, the oldest WW2 Beaufort Bomber left in the world, The oldest CAC Wirraway surviving and one of just five Beaufighters left....
