Yes I do exactly what you propose - use my Oz passport for all flights and for entering and leaving US and Oz (and for the ESTA), and use my UK passport for entering and leaving UK and European countries. I never have any problems. Just make sure you show your australian passport when checking in, even if you're departing through immigration on a UK passport
