I suspect spin will be a significant feature and we're in a nice situation at the moment where two of the most in-form batsmen outside the test side are handy part-time spinners (North and Maxwell) as well as one of the leading wicket-takers in the Shield being a spinner (O'Keefe). So, for mine:
Batsman:
Warner
Rogers
Doolan (could make an argument for Marsh or Hughes here but I want to see more of Doolan before casting a judgement)
Clarke
Smith
Watson
North
Maxwell
Keeper:
Haddin
Bowlers:
Johnson
Harris (if fit - otherwise Starc or Bird would be more preferences)
Siddle
Pattinson
Lyon
O'Keefe
Batsman:
