SYDNEY - Australian Prime Minister Tony Abbott on Wednesday defended tough new terror laws under which Internet data, including websites browsed, will be retained, denying it is an invasion of privacy.
The government plans to overhaul laws to make it easier to arrest and prosecute terrorists and make it an offence to travel to designated hotspots overseas without a valid reason.
It has also substantially increased resources to security and intelligence agencies and wants telecommunications companies to retain metadata for up to two years.
"They're not invading privacy," Abbott told the Australian Broadcasting Corporation of the proposed laws which were announced in Canberra on Tuesday.
"The metadata that we're talking about is information which is already kept. And all we're saying is that the telecommunications providers should continue to keep this.
"We're not asking anyone to do what they don't already do," he added. "We're simply asking that they continue to do it as technology changes, because this is an important weapon in the fight against crime more generally." The prime minister said he had no doubt that the "civil libertarian brigade" would do their best to stop the laws, but said it was his responsibility to keep the nation safe.
"And all of the expert advice from every single counter-terrorist agency is that this information is absolutely essential if we are to maintain our vigilance against terrorist activity," he said.
Abbott said an instructive metaphor was to think of metadata as the information written on the front of an envelope - the recipient, address, sender and the time and place it was sent from - not its contents.
But Civil Liberties Australia director Tim Vines said Internet providers currently collected billing and subscriber information, but had no incentive to retain other data long term.
He said government agencies already had extensive powers to request metadata and warrants to intercept communications between people of interest to authorities.
"Why do we need a scheme of mass surveillance?" he asked.
Katina Michael, vice-chair of the Australian Privacy Foundation, said the mass collection of data left people's private information vulnerable to being accessed by hackers or others.
"We are very opposed to any metadata being retained by the government," she told AFP. "What's that going to solve, save for additional surveillance powers?"
