The agreement, conveniently, isn't legally binding. It's a gentleman's agreement between utter scoundrels, formed to give a semblance of trustworthiness.

As an Australian, I wouldn't trust it at all. The US government has already asked the Australian government for highly expanded information on Australian citizens, and that's above the table.

Stop believing what these people are telling you. They have an awful track record, and the people making the statements now are even worse than the previous people.
