There is no link to any Australian group, think tank or academic centre that looks at these issues. Surely not a true indication of interest and expertise? A volunteer before 2012? (In NZ it's Transparency International.)
I'm sure we would come out of such an assessment fairly well, but it's a reminder that the Federal Government's budget initiative Operation Sunlight may still have a way to go and that some who look closely at these things find major flaws in transparency claims for example concerning the Defence budget.
Here is just one aspect of transparency covered in the Report:
In 68 of the 94 countries surveyed, legislatures do not organize any public hearings at which the public is given an opportunity to testify on the budgets of individual ministries.(Come to think of it, neither do we.) Further, in 35 countries included in the Survey, all legislative budget discussions involving the executive are closed meetings; the public is excluded altogether from observing these meetings, even if they are committee hearings, and no public record of the meetings is provided. In 36 countries, only a few such discussions are open to the public.
