Yes, you can call CAAS. They are quite friendly and will give you medical results.
Even though i've cleared, i've been waiting since March. When I called a certain HR person in SQ he told me still pending.
But some of my friends who went to the same interview are already going to the Australian training phase in Nov.
So very hard to say must wait how long.
I'm also very impatient already, but i've heard from a recent successful candidate that the wait could be as long as 2-3 months or 6-8 months. But even then, no guarantees. For now just be glad you have not heard bad news, cos i also have friends who got rejection email after passing the medical.
good luck
