As with all things CASA, it probably depends.....
If converting a licence for the first time, answer is yes, subject to the usual air law, medical and verification letter etc.
But a while ago CASA ruled against those who were either too indolent or mentally-challenged to pass 'their' exams and instead tried to shortcut the system via the licence-of-convenience route. Most pilots went for a USA ATP, which in times gone by could almost be purchased from a vending machine. Schools that guaranteed an ATP in a week for a fixed price with 'examiner on staff'. Harrumphh.... CASA cottoned on to this and (for a while at least) required the applicant to show proof that they had substantial operating experience using that licence.
So if your mate (and I can guess who it is) is currently flying Fiji registered aircraft on Part 121 operations, CASA should accept a conversion of the ATPL, assuming that he has the necessary hours. Though, having said that, if the ATPL was a validation of a licence from elsewhere (e.g. USA) possibly not.
It could hinge on whether he can get a letter of verification out of the Fiji CAA stating that the licence was an original issue. In some jurisdictions they do no favours for foreigners, in others a brown paper bag solves all problems of this nature and in others they play it straight enough.
