By the looks of the report these crews carried the fuel that the regulator and their own companies required them to carry or in the case of the QF crew even more, but then we're faced with the situation where the forecasts and the observations were not accurate for not one but two airports. Even being set up like that they both got their aircraft safely on the ground. You can bet your bottom dollar that the next time they see a one degree split with less than five knots of wind they will take full alternate fuel regardless of what the met guys and flight planning guys say. Hopefully many others will too.
In spite of the ATSB folk preaching to pilots about getting weather updates most would have to agree that the system failed and the pilots successfully dealt with the unusual situation.
