This may be going off the point a bit, and open to correction, but as a Pom who lived in Australia for a while, it struck me that Gundagai is the place name that is most often found in Australian songs.

The most recent I can think of being John Dengate's "Bare Legged Kate", based on his mother's childhood.

If this is a general thread on bush music, then Wongawilli is a name that should not be left out. They are involved in collecting and performing Ozzie traditional music, but the good part is they are also a great band. There is a web site. A search for wongawilli will find it, I need to improve my knowledge to include clever links. If it is more general follow Alan's link, there is some good stuff on the contemporary Oz folk scene, which I hope to be adding to in the near future.

I picked up a CD by Trevor Lucas, called the Overlander, which has some traditional bush songs on it, but it must have been a re-release of some of his very early recordings, before he joined Fairport Convention. It was in the bargain bin, so I am not sure if it is still available.
