NSW to outlaw unauthorised cyber snooping. www.smh.com.au. March 30, 2004.

Legislation in Australian state (New South Wales) will now prohibit unauthorized e-mail surveillance without a court order. If surveillance is to be implemented then something like a popup warning could be implemented to warn employees of this surveillance (per ABC News story at http://www.abc.net.au/news/newsitems/s1077250.htm)
