Due to apellation controlee we no longer have locally produced Port or Sherry in Australia - Port is now "Tawny" or "Ruby" and Sherry is called "Apera" which is a name dreamed up to suggest "Aperitif".
However serious Aussie wines are generally (but not always) called by grape variety, so you get Merlots, Pinot Noirs etc.
Oz is a wine drinker's paradise if you ever visit here, as it's still taxed more as a grocery item rather than grog. Currently drinking a "cleanskin" for the equivalent of two quid Pommy money which is simply labelled "Fruity White" and originates from "South Eastern Australia". Northern Slope??

It's very drinkable indeed and reminds me of the Moselles you used to get cheaply in Europe from the corner shop as a lunchtime quaffer.
That was four dollars. I bypassed the three dollar shelf to get to it.
