Why are you even bothering with this ? Such a waste of time and money. Almost no one requires you to have an ATPL to get hired these days in oz.
You just need a CPL with an instrument rating and ATPL exams done or in your case the conversion exam and AHUF. You may require a MCC ($6k) however depending on which country you gained your multi crew experience in you may be able to get a certificate of equivalence from CLARC at CASA which is a few hundred $$ instead.
