Yeah not much collection is done on that side of Australia. Coupled with the general thinking that those two species are subtropical or semi-temperate and want generally cooler temps than common reef temps. They are not seen or collect for the hobby frequently. When I was looking in to Clemonops cains Marin was the only ones mentioned to have carried them. If prepared to drop mid to high 4 figures on them, reach out to Cains Marin and see if you can get on a await list or something.
