Ronnie it is the case, and it is QFs policy.
Additionally the policy has been influenced by scared punters (including retarded politicians) running to the media after go-arounds.
As for minimum fuel and QFs policy....well ultimately the Capt decides what fuel goes on. Most follow the policy and then add some. Obviously there are a fair few flights where payload doesnt allow extra, QFs fuel policy is designed to be fairly grey to allow for these situations and therefore can be a little bit flexible based on interpretation. Luckily there are only a few twits who go min op by choice.
I am sure others have a different interpretation, and I certainly dont regard my opinion on this matter as the definitive answer.
