Hi Blaine & Larney.

Welcome to BellyBelly. There is so much info out there its hard to absorb it all, especially when your so excited about starting your family.

My partner and I are also planning on doing the egg mummy/ tummy mummy thing, using Sara's eggs to get me pregnant. We are having a break from it all at the moment though after doing a few IUI's last year.
I think you will find in regards to the surrogacy thing it will be much much simpler if you donate your eggs to your partner rather than trying to nut out the legalities of surrogacy. And like Sally2 said; you will both be legal parent regardless of what the paperwork at your fertility clinic says. Although the having both mums on the birth certificate is NOT Federal law, while lots of the new laws regarding same sex families are Federal the birth certificate thing is still state law. In QLD we still can't have both parents on the birth certificate, hopefully this is changing soon. I'm not sure about SA but you can in NSW, WA, VIC and TAS so who knows.( We Queenslanders are famous for being behind the times LOL)

Like others have suggested its a good idea to get a referral to a fertility specialist now as some clinics have a waiting list for IVF even if you BYO sperm. Also if you are using a known donor they will require the donation to be frozen and quarantined for 6 months before they use it. This is to cover their legal bum bums in case of diseases.
I'm happy to be corrected if I'm wrong but my understanding of the legalities surrounding donor sperm is that because they are a donor they are not a legal parent in any way, so you would technically be breaking the law if you listed them on the birth certificate. Births, deaths and marriages will require their details though but this wont be listed on the actual certificate. If you list a donor as a parent you are also setting yourself up for huge dramas with centerlink too(regarding child matanece payments). I got this info from a legal guide to same sex parenting called "talking Turkey" (google it, its great) It is a NSW guide but heaps of the info is relevant aus wide.
OMG I'm rambling, I hope this is all making sense.

The other thing it will be good to find out now from your clinic is the cost of the IVF treatment, You wont be eligible for any Medicare rebate as you have no fertility issues so everything will be out of pocket.

Your other options for getting pregnant and IUI at the clinic (were the sperm is inserted through a catheter into your uterus at the time of ovulation) which is much cheaper than IVF. Or if you have a know donor you could always DIY at home.

The other thing I wanted to say is don't get too caught up in having DNA from both or you or carrying each others bub. The moment your baby it born in wont matter one bit who's related to who. You'll BOTH be loving doting parents (I'm sure some of the girls on here who have children on here will back that up). Love makes a family.
That said, if this is how you want to create your family don't let anyone stand in your way! I have spoken to other women who have used their partner's eggs, and they were a bit cold towards me when I was asking them questions about how it all worked. But they had done it at the end of very long difficult fertility treatments, as an only option to fall pregnant. I got the impression they thought I was being silly and just "playing house" trying to create an idealistic family.

I'll stop now. I feel like I'm writing a novel, lol.
Good luck with everything, I truly wish you all the best. If you have any questions just ask. Don't be a stranger. Everyone on here is lovely and very helpful.

-Beth.
