I would be pleased to try any Australian Recommendations assuming I can get them here. I did try a bottle of Shiratz from Yellow Tail and I found it pretty bitter. I realize that "Yellow Tail" may well be the junk export wines, so if you have a suggestion I'd like to try it.
At the price the Yellowtail shiraz is good value. Yes, it's a little tart though. The merlot is smoother, but it might be a little heavy for you if you're mostly a white drinker.
The best wine ever made in Australia is Penfolds Grange Hermitage (oops, Penfolds Grange). But as I indicated above it's expensive.http://en.wikipedia.org/wiki/Grange_Hermitage
(Anything by Penfolds will be good. Easily recognised by the simple, stylishly elegant label.)
More affordably, an old favourite of mine (since my youth) is McWilliam's Mount Pleasant Philip Shiraz.http://danmurphys.com.au/product/DM_731 ... lip-shiraz
You might like a red that's a little lighter and fruitier such as a Burgundy (oops, Pinot noir). They also come in whites and sparklings. http://danmurphys.com.au/dm/search/dm_s ... a54ec935c7
One white that I tried recently and thought rather highly of was a pinot grigio made by De Bortoli. It was light and crisp (and the price was reasonable).
One of my favourite Australian whites (again, since my youth) would have to be the Wyndham Estate Oak Cask Chardonnay. I'd be very surprised if that weren't available in the USA.
