Generally in Australia we have had good government but we have to be careful what powers we give them.
For instance a government that is bent on remaining in power(would they ever do that) can know who a journalist is in contact with or who they have been in contact with and when. Be they whistle blower, public servant or a member of their party.
A government can know every contact you make and can glean from that what possible story you are working on.
So we are told this is only meta data, only basic information, journalists above all know that so called basic information is the most valuable, its the first step along the path to a good story.
The reforms have already sparked fears among some parliamentarians of an invasion of personal privacy from laws that would force Internet providers and phone companies to keep every record of a customer’s phone and web use for at least two years.
