Welcome to Geekhack!
It certainly made a difference knowing that you could known a bit off the US price to get the Aussie price back then, but everything back to normal now - multiple by 1.2 or whatever it is these days. I just Google it like "115USD in AUD" for example.
You can occasionally find Model Ms on eBay (even in Australia!). I was lucky enough to find an auction for two that was close enough to pickup.
Keep looking, have patience, and one will turn up.
