Technology giants like Google and Facebook will be forced to decrypt messages and data under new government laws.

The tough new regulations compelling technology companies to hand over encrypted data are borne from concerns terror suspects may be using social media apps to plot attacks.

Under the new laws to be announced today by Prime Minister Malcolm Turnbull, social media providers will be asked to work with law enforcement and government bodies during counter-terror operations, the Herald Sun reports.

The laws will also give security agencies approval to spy on suspects by surreptitiously accessing their devices.

"We cannot allow the internet to be an ungoverned space," Mr Turnbull told the News Corp publication.

The PM has been a strong proponent of tackling data encryption in Australia, with Attorney-General George Brandis and Immigration Minister Peter Dutton meeting with the Five Eyes nations to talk about terror concerns last month.

Data encryption reportedly hindered more than 60 AFP terror operations last month, Herald Sun reports.

The inception of encrypted services and apps has led to a steady rise in blocked content that has hindered Australian investigations. In 2013 only three percent of data collected by ASIO was encrypted, compared to almost 55 percent in recent times.

Mr Turnbull used last week's G20 meeting to urge world leaders to adopt similar strategies to combat terrorism threats.
