Riesling down under

Hi Terry - any thoughts on what’s happening with Riesling out in the southern hemisphere these days? Been very impressed by the quality of some of the dry Rieslings coming out of Australia (Grosset and Frankland River are making some tremendous ones), and some of the off dry Rieslings in NZ. Any general impressions on some of those regions, and has anything from there stood out for you?

I see the wines only sporadically, but have been pleased with a few of them also.
