    Telstra found divulging web browsing histories to law-
enforcement agencies without a warrant  Telstra says it has
divulged customers' web browsing histories without a warrant.
The federal government has been left red-faced following
revelations that law-enforcement agencies have been accessing
Australians' web browsing histories without a warrant.  Access
to phone and internet data held by telecommunications companies
has been the subject of much debate recently, as the government
seeks to extend the power of intelligence and law-enforcement
agencies to fight terrorism and crime. It has proposed telcos
retain customers' metadata for up to two years for
investigation.  However, spy agency ASIO and federal police have
given assurances that data on what websites Australians visit -
know as web history - could only be obtained with warrants.
Now a paper published by the parliamentary library on Monday has
revealed an industry practice of providing website addresses
(URLs) to law enforcement without warrant
