that is a quite common WWT airlines aircraft, quite small and very nimble. (Willy Wag Tail Airlines

) they are like the sparrows back home, all over the place here. they look like the aussie cousin of the fantail, except the fan tail is much more nimble
that was the only anz aircraft i saw, and yes i just had to include it!! all that variety in just over 1 1/2 hours!!
