Labor has thrown its support behind the federal government's $230 million plan to crack down on cyber-attacks.
Opposition Leader Bill Shorten welcomed Prime Minister Malcolm Turnbull's declaration of war on foreign online espionage, which focuses on closer collaboration with business and could involve launching offensive attacks.
"When it comes to national security, Labor and Liberal are in this together," Mr Shorten told reporters in Sydney.
"The truth is if you're a cyber criminal, or you're a people smuggler, or if you're a terrorist, both Liberal and Labor are equally committed, and we work together.
"So we're happy to support efforts to ensure we have the right cyber security."

With the federal election campaign kicking into full gear, Mr Shorten sought to bridge a common perceived gulf between the major parties on hardline national security policies.
"You can vote Liberal, or you can vote Labor, and you can be confident that when it comes to national security we read from the same song sheet," he said.
