The Australian authority on Tuesday has announced a ban of TikTok on government devices, thereby joining a growing list of Western nations cracking down on the Chinese-owned app due to national security fears.

Attorney-General Mark Dreyfus said the decision followed advice from the country’s intelligence agencies and would begin “as soon as practicable”.

Australia is the last member of the secretive Five Eyes security alliance to pursue a government TikTok ban, joining its allies the United States, Britain, Canada and New Zealand.

Earlier, France, the Netherlands and the European Commission have made similar moves.

Dreyfus said the government would approve some exemptions on a “case-by-case basis” with “appropriate security mitigations in place”.

Cyber security experts have warned that the app — which boasts more than one billion global users — could be used to hoover up data that is then shared with the Chinese government.

Surveys have estimated that as many as seven million Australians use the app — or about a quarter of the population.

In a security notice outlining the ban, the Attorney-General’s department said TikTok posed “significant security and privacy risks” stemming from the “extensive collection of user data”.

Fergus Ryan, an analyst with the Australian Strategic Policy Institute, said stripping TikTok from government devices was a “no-brainer”.

“It’s been clear for years that TikTok user data is accessible in China,” Ryan told AFP.

“Banning the use of the app on government phones is a prudent decision given this fact.”

Ryan said Beijing would likely “perceive it as unfair treatment of and discrimination against a Chinese company”.

The security concerns are underpinned by a 2017 Chinese law that requires local firms to hand over personal data to the state if it is relevant to national security.

Beijing has denied these reforms pose a threat to ordinary users.
