They've got a couple of 727 freighters running out of Qld, along with the live belfast.
The current one seems pretty busy, though a little notorious for delays due to engine troubles. I've seen it go through Perth a couple of times in the last year and I've stood next to it once in Port Hedland (presumably dropping off mining supplies, it's a mining town). Last time I saw it in Perth, it stayed on the ground for 3 days due to engine problems.
My first encounter with the belSlow was stepping off a 146 one morning at a normally empty airport, looking up and discovering that you can put turboprops on something bigger than a fokker 50 and that there was a plane even cuter than a quadrapuff (I think I have a thing for fisher price looking planes). The guy sharing my taxi that day couldn't shut me up about it the whole ride!
Standing next to the Heavylift was probably the moment that turned me onto planes forever and sent me scrambling looking for aviation jobs, so I'd have to say a second airborne one would be absolutely WONDERFUL!
Failing that, I'd like a nice little diecast model one for my desk at least..sigh..what I'd give to go for a fly in that thingy! What are the rules about shipping yourself as oversize cargo again....
Toast.
