Not baileyane, which has a maximum of 6 pairs of leaflets per leaf. Probably Acacia dealbata http://worldwidewattle.com/imagegallery/image.php?p=0&l=d&id=23625&o=1 but it could be Acacia mearnsii http://worldwidewattle.com/imagegallery/image.php?p=0&l=m&id=17958&o=1
I didn't load the best photos and the app put them in the wrong order. I have reordered them and will delete and re-post the bright green one. When I scanned some branches and sent them to Sydney in 2010 I was told one could be a hybrid, but now it looks more like A. mearnsii. There is also A. dealbata and A. decurrens in this little patch.
