Or worst case, book a very cheap flight from anywhere in Asia to anywhere in Australia post the 6 weeks but prior to the maximum trip length of the policy. So, her trip would end in Australia. If she has any major issue while in Asia that would require a claim against the policy, it would be perfectly understandable if she changes her travel plans and rather flies back to Ireland where she has family. Having both citizenships makes it very plausible that she would end up in either country at the end of her trip.
