Hi Michael, yes, a good list of current orchid taxonomy can also be found here: https://www.anbg.gov.au/cpbr/cd-keys/orchidkey/html/currentspecies.html . My understanding is that there are not many true Dendrobiums in Australia any more, most have been separated into other genera, such as these Dockrillia. Might be good to ask @Tapirlord as well.
