Hi there and welcome!
Unfortunately in Australia PGD/IVF for family balancing reason is banned...stupid government we have... dont get me started on that!
The only way you can have it done in Australia is if their is a genetic reason for it, eg a genetic disease in your family specifically affecting males.
I am also currently looking into the possibility of going to Thailand or USA, I am just waiting for a repsonse back from Jetanin. But to go the USA and do IVF/PGD and Microsort, including your arifares and accom (for 2) will cost you in the range of $25,000 AUD for once try....ouch
GL :)
I am also desperate for a baby girl :(
