Thanks Gary. yes, they're Dendrobium affine, a common native here. They like it along creeks or swamps, preferably on Melaleucas (Paperbarks). But see them sometimes on Pandanus and Cycads. They like the rough textured trunks. I sometimes have trouble from possums, about the size of large cats. They scamper up and down tree trunks and anything in the way ...... "Bad luck!"

Pretty, but be careful about "rescuing" native orchids. They are protected plants and people have been prosecuted for removing them from the wild. I have a friend who does land clearing, and he says they are not even allowed to give them away. They have to call some agency and they come and get them and relocate them elsewhere. He isn't allowed to remove the logs until the orchids are moved, which, of course in this beauracracy, can be quite awhile.

As I said in my original post they were growing on my place. So they weren't in the "wild", and the need for rescue wasn't the result of land clearing. This species isn't listed as endangered, nor even vulnerable, although it is still protected in reserves and on public lands.

They look really happy to be alive and rescued :D I wish I could do that, tie orchids to trees but it freezes too often here :(

Hanging from trees can look really good too, and you can move them into shelter when the weather turns bad.
