Bad oversight by 2 crews, how did the aircraft leave Oz without the full route package. It is this second point that needs addressing by QF. There is something systemically wrong when this sort of event occurs, and this is not the first time charts have not been on board and a diversion was the result.
Trouble is it is easier for this current management to get the boys and girls in for tea and bickies then to go and find a solution to stop this happening again-ever.
