Australia will not officially disagree with the Indonesian findings because it would not be a good move diplomatically. I think there was also some mention on the documentary about Indonesia and Singapore giving Australia free access to accident investigations which involve their nationals. I do not exactly understand this but it would appear that if Australia upsets either Indonesia or Singapore then they will make things difficult for them. The thing to realise is that this investigation has been compromised by politics. It is a sad inditement on our polititians that they care nothing for the safety of their people.
