At a press conference this afternoon, Malinauskas advised he would be speaking with the state’s chief information officer today for advice and would then make a decision quickly about protecting South Australia’s information.

“I already don’t have TikTok on my phone for security reasons,” he said.

Attorney-General Mark Dreyfus announced the Federal Government ban on Tuesday after receiving advice from intelligence and security agencies over the platform possibly being used for foreign interference by China.

He said the directive would come into effect “as soon as practicable”.

“Exemptions will only be granted on a case-by-case basis and with appropriate security mitigations in place,” Dreyfus said in a statement.

Concerns over TikTok relate to the potential for data to be harvested and accessed by the Chinese government under national laws that can compel companies to hand over information.

Victorian Premier Daniel Andrews, who has more than 100,000 TikTok followers, earlier confirmed he would delete his account, but had not yet been briefed on the national security advice being considered by the Commonwealth.

He told reporters his government would follow the lead of its federal counterparts on matters of national security.

A cyber security expert flagged the public’s use of the app should also be reconsidered.

“I do wonder whether or not there needs to be some broader action,” CyberCX chief strategy officer Alastair MacGibbon said.

“This is not around things made in China, as it’s often depicted, this is an argument about things controlled by China.

“There’s a fundamental difference between normal electronics manufactured in China and electronics that are controlled essentially under the laws of Beijing.”

Opposition security spokesman James Paterson said Australia was behind other countries such as the United States, United Kingdom, New Zealand and Canada which had implemented a ban on government devices.

He said TikTok represented a serious espionage threat and wider action to protect the public should be the government’s next step.

“The data privacy and security risks and also the foreign interference risks that affect millions of Australians who use the platform are so far not yet dealt with,” he said.

“They have to be dealt with. Dealing with it on government devices is only the start.”

But Greens senator David Shoebridge said the government’s directive had missed the point and did not confront data security problems.

“The data security issues for TikTok are mirrored in pretty much every other social media platform – the difference is that our government is not running a fear campaign against the governments that host those platforms,” he said.

“Banning TikTok from government devices is a publicity stunt which masks the fact our data is being exploited by every corporation that can get its hands on it – social media platforms, health apps, the games our children play.”
