A staged terrorist event will test how well social media platforms in Australia manage to stop the spread of violent extremist material.
And Prime Minister Scott Morrison has put them on notice that if they don't come up to scratch, he'll be coming for them.
A task force of social media companies, tech giants and Australian internet service providers formed following the Christchurch attack has laid out how the companies will act against material that shows an actual terrorist attack or violent crime, or encourages people to commit one.
The release of its 30 recommendations on Sunday comes on the heels of Mr Morrison convincing the leaders of the world's largest economies to join action against the spread of terrorist and violent material online.
"(Technology companies) need to apply as much of your energy, resources, effort, innovation, technology, to addressing this problem as you do to sending me an ad to go and buy a new T-shirt when I look at something on the internet," the prime minister told AAP in Osaka where he attended the G20 summit.
"They're very good at that. I need them to be as focused and good at making sure terrorists don't use their product as a weapon."
He said it would be very hard for the companies to now think they could do nothing.
"Because frankly, if they do do nothing, I'll be back. I'll be back saying, 'Well, you know, I think we're gonna have to go further than a statement'."
Google, Facebook, Twitter, Amazon, Microsoft, Telstra, Optus, Vodafone and TPG make it clear in the task force's report they recognise the government is willing to pass further laws and regulations if they don't act.
The Morrison government has already enacted laws to make it a criminal offence for companies not to take down videos that show abhorrent violent content, and these were held up to G20 leaders as the gold standard.
The tech companies have promised to review their algorithms to make sure they aren't pushing people towards terrorist and extreme violent content and to set up better and easier-to-use reporting mechanisms for people to flag content.
Live-streaming services will set limitations on new users, possibly including a 24-hour "cooling-off" period after signing up or limiting their audience size.
They will have to suspend users who repeatedly breach community standards and have processes to quickly deal with flagged content.
The industry will develop a new online crisis response protocol for dealing with terrorist and extreme violent material, which could be extended to all media companies.
A test terrorist event in the next 12 months will demonstrate how well the new systems are working.
And companies will report twice a year to government on how many items have been flagged, how many blocked or removed, the time taken to review and take action on flagged content, and how many views it got in that time.
Mr Morrison told AAP the task force's suggestions were ahead of the curve and would be shared with G20 leaders to inform their actions in their own countries.
He said pushing for action on the world stage was the most practical thing Australia could do for its New Zealand cousins after the March attack, when an Australian man allegedly killed 51 Muslims at two Christchurch mosques and wounded dozens more.
"Christchurch was a truly shocking event and having been there for the memorial service and met the victims, this was the very least, I think, Australia could do," Mr Morrison told AAP.
