Yes to both however . . . 

A few minutes after making my post I did several searches and all worked perfectly!

In one instance all listings were from Australia. and in another with only a few Australian items, AU was at the top, followed by a heading  "Overseas Listings". Today is the first time I've ever seen that. I do web programming, so my browser cache is cleared several times a day.

Let's hope it keeps up because I've often had to plow through several pages before finding one AU listing.
