Here's a video from this comedic dance sequence... I haven't seen anything in better quality, but 1934 Australian films are probably a little hard to come by. You can see the whole film on Youtube

Well, I watched the scene and then some (my first impression: terrible movie), but the dancer seems to be randomly chosen, grabbed and danced with. Makes little sense to me and I don't think I can watch the whole thing.
Anyway, there seems to be a ton of uncredited actors and actresses in that scene and I fear the dancer is one of them...!
