I am attempting to upload some new items from Turbolister but the following error message returns for all iems.

"Postage cost cannot be calculated when item is located outside US. Use flat rate postage"

I am in Australia and on the Ebay Australia site. Yes, item is outside the US.

International postge from Aust depends on buyers destinations.

What box haven't I ticked correctly? I have put these up exactly the same as all my previous listings?

Thanks
