Welcome!! thanks you for your kinds words. I personally don't know of info in aust. But I do know of a woman (IM) from Australia who is using a surrogate here in the states. I can ask her if she will contact you to help you with all the information you need. Just shoot me a message with your private email and I will give it to her.
If there is anything I can help you with, I don't mind at all, just ask!
