Has anyone been approved to leave australia for medical treatment - in this case, the IVF treatment embryo transfer?

I just read the rules and surrogacy etc is ok but medical treatment has to be evidenced by the treatment is otherwise not available in Australia. Other option is a compassionate ground under other general I suppose.

If we do give details about why we don’t use IVF in australia, we are basically letting the gov know we are using donors, indirectly. I wonder if they would grant us ok to leave Aus for that??
