I've just read the Sydney Airport Curfew Act 1995 (one of the shortest Acts of Parliament I've read).
Unless it's been amended, section 7, subsection 2 clearly states that 'the Operator of an aircraft commits an offence' if the operator engages in conduct which results in a contravention to subsection 1 (which details the prohibition and exceptions during curfew periods).
Nowhere does it state that the Pilot In Command is liable under the Act.
In another section it also goes on to state that the airport can be used during emergencies, and for other approved operations.
Nor do I recall any Notam that states ARFF is reduced during curfew periods.
So please help me out with some references, and I'd be mighty grateful.
Personally, I say well done! AJ for putting pax ahead of profit on this particular night.
