Would likely be more in line with north America or southern Canada down here, I like to make up nucs for over winterering in late August and through September, after they have collected the honey crop.
I made one or two up towards the end of October, more by accident than design as I had the queens in the truck ready to requeen hives which turned out not to need them so utilised the queens by pinching a couple of frames of brood from strong hives. I've marked them out and will be interested in their condition come spring.
