The Australian implementation is "metadata", but what that is and means is still rather ambiguous. After a five year court case, the Federal Court decided in 2017 that the average citizen isn't allowed to access all data that may be about them, despite being allowed to do so under the Privacy Act. If that sounds ambiguous... It's because it is. Without an ability to say with is metadata and what is not, everything may be getting stored, and some companies will be overly conservative in how much data they are storing. Not to say that this is worse than the Chinese implementation which is far more explicit in its demands for privacy invasion, just that the Australian case is... Worse than it sounds.
