Probably the the easiest place to find what ReMix birds are available is to check the ReMix bird plate Library (http://www.empken.com/SongbirdReMix/sbrmplates.htm),  

On the left column, you'll notice a List starting with North America.... scroll down about 3/4 of the way and you'll see Australian Birds. Click the bird on the list and the render (with no postwork) will appear in the right frame. Hover the mouse over bird name on the list and small window will appear telling you what package it's in or whether it's free in my downloads.

4 Australian parrots should be released in the next week or so (at DAZ) in my "Parrots of the World" package. Which 4? The Galah, Red-tailed Black Cockatoo, Crimson Rosella and the Night Parrot.  "Pet Shop" has a healthy dose of Australian birds too (Budgies, Zebra and Gouldian Finches and Cockatiel). Since you have SBRM2, in my free downloads there's the lesser and greater sulfur crested cockatoos (http://www.empken.com/downloads/downloads2.html).  I'll be updating those within a week with a new improved cockatoo crest.

And finally, those of you with DAZ|Studio, I have updates available to make your DS birds load and look a lot better in my download section.
