Back to topic.
I think that Cullen is a great find and has finished the season extremely well. He would be (on current form) the 3rd best spinner in the country behind Warne and MacGill. Hauritz needs to get his groove back, White doesn't bowl enough overs to be considered a top line spinner (an allrounder maybe), Doherty has had shocking figures and looks to be in the same league as Hauritz at the moment.
On the batting front Jaques has had a great season and could leapfrog Mike Hussey as the next opening option. I think that the selectors will stick with Hussey. David Hussey has disappointed this season after a hot one last season. Callum Ferguson and Craig Philipson have shown promise and you can't knock the class of Rogers and North from WA. Thornely may also be a contender next year.
The next fringe of fast bowlers includes Tait (obviously) but there are no real other youngsters in line other than maybe Griffith from Tasmania. Mitchell Johnson needs to get a full season under his belt.
Haddin will go to England as reserve keeper. Seccombe has disappointed with the bat and Hartley may be too good to ignore next season. No other gloveman has done enough. Ronchi can't get into the FC side for WA so who knows how good he is. Crosthwaite has at least played a couple of games at the end of the season.
My top XI of guys who have not played a test yet is.
Hussey, Jaques, Rogers, Hodge, North, Thornely, Haddin, Cullen, Tait, Griffith, Harwood (struggling for last bowler, could also pick Wright, Rofe, Dawes, S Clark)
