The problems with water and the Murray-Darling system are very serious for Australia. One could liken it to a similar fate befalling the Mississippi. The area called Southeastern Australia on a lot of wine from Oz is serviced (in part) by these rivers, and the recent lengthy drought has been severe. (see
here) However I drove through part of this area in mid-December last year. Going west, once you pass Balranald in NSW, you begin to see vineyards and while there were small areas of vineyards that did look dead the vast majority of vineyards were green and lush, much greener than the surrounding countryside. The grapes here go to both wine and the table including sultanas. While the grape harvests may be falling its clearly not an economic disaster, at least on the macro-scale; some individual farmers may suffer.
What was more interesting was the scene in the Barossa Valley. The vineyards looked stunning in their green leafy coats, while all else was dried and without color. There will still be plenty of wine coming from Oz.

FYI: To appreciate the importance of the Murray-Darling system to Australia click here to see that
The Murray-Darling Basin is 3,430km long, drains one-seventh of the Australian land mass, and is currently by far the most significant agricultural area in Australia.
