I particularly like a white wine as a sundowner/pre-dinner type of drink.
I'd suggest trying some of the IMO pretty decent Pinot Grigio/Gris from Australia and NZ that are around now. Vintage Cellars, and probably Dans, has a quite extensive range these days.
Also try some of the Italian and Spanish varietals: there are some good Vermentinos and Fianos being produced in Australia now, and Arneis, but that tends to be a light style that some may find flavourless. Soave (not a variety as such, but made from Gargenaga) can be a good food white
I like Spanish Albarino but any that are available are from Spain despite an attempt to grow it in Australia. The first attempt to introduce the variety was stuffed up when it was found after several years that producing vineyards were in fact the much poorer Savagnin. A disaster! There are now some true plantings that may soon see Australian Albarino. Vintage Cellars has a couple of fairly ordinary ones; the really good ones can be sourced from more specialised retailers (and can be expensive - but worth trying as something a bit different IMHO).
Assyrtiko, from Santorini, is hard to get but is a lovely wine. Look for Sigalis, the top producer, in a specialised wine store.
Hopefully that's something for you to go on with
