An anonymous reader writes: Australian Telecommunications Giant Telstra has for a decade been storing huge volumes of electronic communications carried between Asia and America for surveillance by United States intelligence agencies. This includes not just the metadata, but the actual content of emails, online messages and phone calls. With the blessing of the Australian government Telstra agreed to route data through a "US point of contact through a secure storage facility on US soil that was staffed exclusively by US citizens". The contract was prompted by Telstra's decision to expand its business in Asia by taking control of hundreds of kilometres of undersea telecommunications cables. The deal started under the Liberal Party and continued under Labor. The Greens have demanded an explanation.
