GaryGnu,
I have been told.
There are at least 30 Capts at this time with more than 2000hrs Airbus, and some 15 at least with in excess of 6,000hrs on A320's, in 12 months time when or if the a/c arrive there will be about 60.with at least 1500hrs on type in command.
However I am told that the 2000hr requirement from CASA is going to be relaxed to more like 1,000 hrs, therefore J* pilots will be able to crew the a/c without the need for any direct entry captains.
And remember the a/c don't all arrive on day 1. It would be a gradual ramp up and consequently be quite manageable albeit busy.
