Interesting that nobody I've talked to over here seems to be that surprised about the extensive data collection. A few people are annoyed about the unaccountable way it's been done and the abuse of power, real or potential, though.
It takes a lot to shake Aussies out of the "she'll be right" mentality, and we don't have a Fourth Amendment to be violated like the US does.
I also fear that the aware, technically literate people here won't attempt to move Parliament House on the issue, they'll just resort to stronger encryption.
