Judd - CASA have deferred the MCC requirement until 1/9/2015 (refer FAQ on CASA website)
Civil Aviation Safety Authority - Frequently Asked Questions ? Flight crew training and licensing
When the MCC is introduced it should be incorporated in all Type Rating courses, given you'll need to do the flight test under multi crew conditions, in a multi crew aircraft, the type rating will achieve the MCC requirement.
I've searched and can not find the current Jetstar requirements on their website, maybe you'll find they too will accept ATPL subjects.
