How old is the queen do you think? If she is still sound as a layer there should be frames with brood in the middle of the brood frames even thou it is our so called Winter, it is more like a Summer climate in other parts of the world. I was down on the Gold Coast a couple of months ago and all the hives where really strong and swarming was an issue then. If your not seeing capped worker cells but seeing only capped drone cells then I would suspect you have a laying worker bee. Maybe what you have seen as a queen is a drone, a photo would be a help if you can get a photo of her. Normally a queen rite colony doesn’t have a laying worker, and in the cooler weather drone number should be down in numbers. If the queen is a poor layer it wouldn’t achieve anything in moving her. If you can get a frame of capped worker brood that can be a help.
Cheers
