Hi Kerry & Linda, welcome!
There is heaps of information out there, it just takes time to sift through it all. I'm sure you've cruised through some of the threads on here, there is a couple of websites mentioned on some of them to give you a great place to start.
Try
Pride and Joy online it is Victoria but has lots of links to gay and lesbian parenting/conceiving websites.
You have lots of options, your main one being known or unknown donor! Good luck girls, there is lots of discussion on here about everyone's journeys, I think some of the really relevent ones to you are on the second page so read those if you get time.
