I prefer the text out to the side as in #35 but would like the main emphasis to be on the words "Nature Photography' rather than "Australian"
I don't know if I like the letter 'A' in the middle of the blades as when I use the logo without the text this won't mean much. Maybe a bird or animal coming out from the centre?
The hovering birds around the top are a nice touch :-)
#43 : I like this design (the yellow dot more than the red), however I would need a more Australian animal than a giraffe. They are only seen in Zoo's over here :-)
