I think it's fair to say Australia usually has the most varied wickets in world cricket, though in recent years they've pretty much all been flat, like in most parts of the world. Last year we had a bit more variation than we have for a while, so if that continues we might get 5 fairly different pitches, which should make for a more interesting series.
Traditionally, Brisbane favours swing bowling, particularly if it's overcast, and you can occasionally get really lethal wickets there. Fair to expect a bit of movement on the first morning and maybe even the whole first day, then it will flatten out. Warne also loves it because of the bounce, even though it's not really known as a turning pitch and Panesar probably won't get much help.
Adelaide is usually the flattest test wicket in Australia, excluding Bellrieve, and is very good for batting for a few days and will usually turn on days 4 and 5. Australia will almost certianly play two spinners.
Perth used to be the fast bowling heaven obviously, but the last few seasons it's been very flat and if anything favours spin more than pace. Huge scores there in the Pura Cup so far this season, so I'd expect an absolute road.
Melbourne was pretty seam-friendly last year so hopefully we'll get more of the same. It's pretty unpredictable these days though, given the drop-in wickets they've been using. Traditionally it's the most seam-friendly pitch alongside Brisbane, and so Australia probably won't pick MacGill here either.
The SCG is normally the best wicket for spin in Australia, and it's also late in the season by the time the SCG test rolls around, so it's usually dry and will turn a lot, especially on the later days.
The above are all generalisations, and it's entirely possible that every wicket will be a road or that Adelaide will be a minefield or whatever. Now you know as much as me, though.
