Snowden called the laws a dangerous example of a liberal government’s violation of civil liberties and promised to reveal more documents on Australia’s intelligence operations.
"Australia is one of the most aggressive countries that engage in mass surveillance as a member of the Five Eyes Partnership," Greenwald told ABC broadcaster Thursday night.
"Australia is probably the country that has got away with things the most in terms of the Snowden revelations… We definitely intend to change that," the journalist added.
Since 2013, former National Security Agency (NSA) contractor Edward Snowden has been leaking documents that have exposed numerous global surveillance programs, many of them run by the NSA and the Five Eyes with the cooperation of telecommunication companies and European governments.
