Telstra caught disclosing browser data without a warrant

Recently the Australian government started down the path of changing laws to collect metadata for two years. In response to claims that this type of data retention would be abused Prime Minister Tony Abbott's office stated "The government requires a lawful warrant to look at Australians' web-browsing history. This is not metadata, it's content". Now, just two weeks later, Telstra has been caught releasing this type of data without a warrant. Critics of data retention have stated that this would happen eventually, that data would be released without a warrant. Now they can say "it is happening now".
