I have some information. First ground school starts mid August but is in Brisbane so Brissy people will be contacted soon with dates ect ect. They are out of the office this week and will be back Friday (I think) the delay in getting the emails out re the medical is due to the huge number of people they are employing. If you are at the waiting stage you can call them and they will let you know if you have passed. She did mention to me that if I had not made it through I would have known via email by now (if you were on one of the original VRD's) Sydney ground school starts 15 September for 6-7 weeks and there are 11 ground schools for Sydney planned.
I had a friend go for the recruitment day in Sydney on Tuesday 2nd July and she mentioned that a lot got through.... there was about 1/3 out of my day that made it so maybe they are relaxing the rules a little due to numbers.
If you need to know what is happening they are more than helpful when you call them and it eased my mind!
