Prime Minister Malcolm Turnbull says an “open, free and secure” internet is vital for Australia’s future prosperity.

Introducing the Government’s $230 million cyber-security strategy, he says the plan sets out a “philosophy and program” for meeting the challenges of the digital age.

“A secure cyberspace provides trust and confidence for individuals, business and the public sector to share ideas and information and to innovate online,” Mr Turnbull said.

“The security threats we face are real and they are growing in severity and frequency.”

He argues the cyber-security strategy is critical to Australia’s transition to “a new and more diverse economy, which is fuelled by innovation”.

“We cannot allow cyberspace to become a lawless domain. The private sector and government sector both have vital roles to play.

“By working together we will build and strengthen a trusted online environment and unlock Australia’s digital potential.”

The strategy comprises 33 distinct programs, and will directly result in the creation of more than 100 jobs.
