EMQ is a government run operation to my understanding. I ask why would they go to the cost level of training flight crew just to bring them under CASA regs for flight duty time, when they just need to introduce it into their SOP’s. CASA requires Pilots to work to flight duty hours but the area of operational flight crew is left to the operators. Any responsible company would place a flight duty time on their crew to minimise their risk exposure to in flight or work place incidents.
CASA rules are in place for guidance and for limits. There is no rule to state that flight and duty limits can only apply to pilots, the same could be applied to engineers, crew and management if a company is responsible enough.
These limits may vary to hour duration but assessed on work to be performed and risk associated with it.
