RAAus can count for none of your CPL [CAR 5.111, 5.114]
Have a look at CAR 5.104 (1) (f) (ii) which includes reference to CAR 5.115. Then have a look at the definition of "recognised flight time" in regulation two.
You might then wish to reconsider the 'none' statement, if you so desire.
As for doing a CPL based primarily on RAAus hours though? Probably not the best idea.
