"Frankly there does not seem to be any aviation related event in Australia that is targeted at GA, the closest being the SAAA show at Narromine, which I hope to attend again."
Yes, been to the Narromine show, 2012 or 2013, can't remember now but I thought that an organisation in Queensland ran a big show, aimed at GA? Sorry, can't for the life of me remember the name of the organisers, just that it is a fairly big show.
