I grow this one but I am also lucky enough to be within its native range and have it growing on rocks not far from my house! It is indeed very hardy, I have had bits fall to the floor of the patio only to be found when I swept behind the pots and they were growing happily :P.
I have just remounted mine on a net mount made out of plastic gutter leaf guard mesh stuffed with a mixture of sphagnum and live moss. I think it will really like this mount but time will tell.
If these home made mounts work well I plan to eventually use them to make a patchwork 'green wall' in my patio.

I would contact the Australian Orchid Nursery. They may not have it on their site but I suspect they would stock it and other members had plants shipped overseas from him recently.

Here is the one I just mounted, there are a few other bits floating around the pots but I am hoping this one will expand to become a nice specimen for me
