It was an EMQ helicopter that rescued the Capricorn Bell407 crew off Rockhampton some years ago - at first light. These type of rescues can only be safely carried out with two instrument rated pilots
If this rescue/winch operation was carried out at first light (which it was), why do you need two instrument rated pilots up front??
Another question... why the need to have an ATPL(H) to fly the AW139? EMS/SAR work in Australia is classed as aerial work.
