I'm also in the US, but I do know that Australia most definitely has them (I'm actually going to try and get a friend to pick some up for me)! So if you can find an Australian member willing to help, you should be set. Good luck!
If there's just one or two that you're after, you could always tell me which one and I'll add it to my list. I'll then send that list to my friend and if she's able to find the one you want, you can pay me, then I'll pay her and she can ship our Zelfs here in one box. Once they get here, I'll send your Zelf to you. If that sounds good, drop me a PM!
Haha, I just now noticed which Zelf you want. If this plan sounds good to you, I'll add a second Gar-Girl to my list for ya!
