I don't have any in e-book form, so can't give very specific recommendations. I can see that some do exist but look like they have accessibility problems outside Australia.
I was always partial to Judith Wright, and see Kobo AU have a
collection here, and Kobo US show it
here.
Kobo also have this humongous collection: "
Australian Poetry Since 1788"
AU US. This is more like the wide ranging selection you were looking for, with work from many poets, but it is huge and so correspondingly expensive (and my searches on Amazon didn't show it as anything but hardcover, if you normally shop there). Maybe a library will have it?
