Yes....I think the Vimy should probably stay in Adelaide, and it is regrettable how remote the Southern Cross is in BNE now....I've visited many times of course...but it gets harder. I was in Tamworth this time last week and my Son and I stopped to look at the East West Avro Anson...again, not terribly easy to access.
Caboolture, Caloundra & the once a month Amberley Museum are all enjoyable, and after driving to Tamworth not too far from here! .... All very enjoyable little museums!...
