You're sure they were for Australian residents and not imported search results from one of the other sites?
Hmm, I may have been mistaken then. If that's the case, though, I still don't know why it wouldn't be showing up for you.
Can you post one of your item numbers or a link to an auction so we can see if it shows up for anybody else?
By the way, you might also file a support case (bottom of the Help page) and maybe Auctiva staff can give you a direct anwser.
