Its all OK .....CASA is onto it
To wit
The Civil Aviation Safety Authority’s stance on fatigue management in Australia is about managing the risk of fatigue within a defined environment or work setting, and not simply about managing the work or flight and duty times of operational personnel. Each organisation and individual has a role to play in contributing to managing and mitigating the potentially hazardous effects of fatigue.
CASA’s focus is on scientific, evidence-based, fatigue risk management. As a result of ongoing participation in such research, CASA proposes to issue guidelines for fatigue risk management during 2009.
