I have had this problem for 2 days, but it seems to be fixed now.

I could not get Aust only and a search that normally brings about 1200 items was returning about 115,000.

The Ebay IT monkeys definitely hit the jackpot with this effort! 

I can just just see them all jumping up & down, screeching madly and hi fiving each other...

Instead of;

(a) only alienating those who want to search only within their own country, or

(b)  only alienating those who want to search only overseas,

they managed to screw everybody!

Both here, the US and UK were full of complaints that whichever locations were specified, you only got the alternative & it was impossible to change parameters;

i.e. tick your home country only and you got bazillions of listings world wide, or if you wanted worldwide, you only got your country's listings!

Thank goodness I only buy here and did not have to put up with Ebay scrambling my selling prospects.

I had a number of things on my watch list that ended in the last 2 days and I saw that some of them finished with MUCH lower prices than normal.  Maybe people couldn't find them amongst the mass of overseas listings?

And the Oscar goes to...  EBAY!!
