Yep Centrelink is changing, well I suppose change is change even if its a bit lopsided. Medicare is also recognising our families too which is really cool I imagine everyone in a defacto relationship would lose their single parent payment.
Not sure about the tax laws... I thought FTB goes on combined income, so regardless of who can claim it would still go on your combined income, so your income if that the only income?

do feel sorry for those other girls in SA who can't access anything here because they are healthy.
That is sad, I think if you're willing to pay for it then why not, no one should be excluded just because they aren't medically infertile, I just don't think Medicare should fund someone who isn't medically infertile (the way I see it you and I would have probably needed help if we were in a straight relationship so it was coming to us anyway ).

ETA: Bath missed your post... Shel and I have never been synced (we have overlapped a fwe times but nothing regular) so its not too tricky we are just sensitive to when each other needs space and thats that, not too different to a straight relationship
