Part 61 and the ATPL is fairly straight forward - The MCC is mandatory after September 1st 2015 for initial multi-crew type rating and initial issue of an Australian ATPL. To gain a type rating on a multi-crew airplane (above 5700KG) is by way of a Level D sim - and then conducting the ATPL Flight Test integrated with the type rating.
Contact MATS, They seem to have trained a number of crews recently.
