Sydney90,
There are at least 4 ground schools taking place right now. All will be finished just before Christmas but will take up most of December.
Also for those interested the governments Parliamentary Committee into Cabin Crew Ratio have recommended that the 1:36 ratio stand and that any airline such as Virgin Australia that has an exemption of the 738 to operate 1:50 (4 crew) will not be renewed when it expires.
That means if passed and accepted that all 738 services in the near future have 5 crew. There are other changes happening anyway though that have led to the sudden recruitment and massive increase in cabin crew required.
