Other than the dead c all of these are Australian. Just thought I'd mention it because usually it's New Zealanders getting mistaken for Australians. If you haven't heard Menstruation Sisters check them out. Its Oren Ambarchi on drums, Nick who also played in Phlegm on guitar and another guy named Brendan on bass. They played for the first time in 6 years about a month ago and it was nuts.

Although I like her music, Bjork is not really a band, well, properly anyway. An aside, but Neil Young was born in Canada, of course.

So, disqualifying any groups with members from several different countries and bands who have some members from the U.S. or U.K., and for the purposes of answering the topic question, my favorite current band is the wholly Japanese OOIOO. (I'm supposing that this P-We project is going to still continue to make records).
And my favorite one that has clearly already peaked is the entirely Australian INXS. (I refuse to acknowledge the new version).

Konono No. 1 (Democratic Republic of Congo)
Getachew Mekuriya (Ethiopia)
Tinariwen (Saharan Africa - they're nomads, so live all over the place).
Jennifer Gentle (Italy)
Celtic Frost (Switzerland)
Monarch (France)
Negura Bunget (Romania)
