It's really hard to tell since the breeding program for australian dens has gone full throttle... but it does look like a d. kingianum hybrid perhaps with d. jonesii in it... or maybe a form of jonesii that's pink? and maybe something else to get more spotting in there?
Thank you for the answer to my Question.
My wife pull tags to look and forget to replace them.
Now, then repotting, I put extra tag on the bottom the pot.

Good luck with the identification. It certainly looks like a kingianum with some speciosum influence but positive ID due to the number of Dendrobium crosses out there may be difficult. Nice flower though does it have a scent? If so you can tick the box with Strong speciosum influence.
