Warrentless searches of subscribers' metadata have apparently been surreptitiously occurring for years, as indicated in The Canberra Times on 20 August 2014:
* when and where online communications services start and end;
* a user’s IP address;
* type and location of communication equipment; and
* upload and download volumes, among others.
One rather suspects that with this definition of retained metadata the Federal Government and its agencies can do a lot more than keep alert to any alleged domestic terrorist threat.
There is room for 'function creep' to become established.
The 2010 version of consultation concerning the proposed data retention policy also clearly outlines an intention to monitor the daily habits and social networks of ever Australian resident via their Internet and telephone use.
