It is dependent on your CN number Nic, Ally is lucky enough to have a number in the low 300's where as I am in the early 2k mark. Each month they release the numbers for interview based on these cn numbers per region.
Thanks - that makes sense. Do you know if they let you know by email or post?
What range are you in Nic?
Yes you can check the monthly release, it is currently at 375 for Oceania ( November dates)
