CASA allowed three years for the industry to work up the data on their roster practice.
- resting periods were to be in accommodation, not in transport
- "unforeseen operational circumstances" were the only way duties could be extended over statutory limits. (not east coast summer CB)
- rest periods were inviolate.
Of course the operators did not have the data and could not crew the flying, so CASA kicked the can down the road...
With Qantas (am told) now critically short across most fleets and ranks, serious issues with training capacity, expect more can kicking..
Anyone considering extending should consider exactly what the new regulations allow (and consider fatiguing) before making the decision to leave the protection of the statutory limits..
