The OZ national authorities got very uppity about their data and have successful extracted Megabucks from Aerad (or whoever they are at the moment) and have tried (but it is unclear if they succeed) to get money out of Jepp. In addition, I am lead to believe the Oz position was a factor in convincing the US government that the DAFIF data should no longer be publicly available (as they were republishing the data provided by every national AIP).
