As for the cause, I've not seen anything but I've been out of the loop since I retired.
The question is who sign's off on a "double engine failure" flight permit and what conditions, inspections/test are required before such flight?
No risk in double failure or even roll back around either Melbourne or Sydney to anyone other than crew.
I can see the Flight Permit now - both crew must watch "Miracle on the Hudson" immediately prior to flight.
