Very little data around for this at the moment.
It looks like it went ahead with a very low number of invitations, maybe as low as 400. We have seen mostly Accountants so far and one IT occupation (unconfirmed)..
We have seen invites for Accountant at 75 points for both EOIs of the 13th (emailed to us) and 16th October 2017 (online). As well as several 80 pointers emailed to us.
We will update as soon as we can get more info. If you have details of any 189 invites please email them direct to us at query@iscah.com
