The Australian government has demanded Facebook immediately restore official public safety pages such as health departments and emergency services as soon as possible.
Facebook has said it would do so, and has begun lifting bans on some government and other non-news services.
After being blindsided by the tech giant's decision to ban news content, Treasurer Josh Frydenberg said the actions of Facebook were "unnecessary and wrong".
"Their decision to block Australians' access to government sites - be they about support through the pandemic, mental health, emergency services, the Bureau of Meteorology - were completely unrelated to the media code which is yet to pass through the Senate," Mr Frydenberg said on Thursday.
The Treasurer rejected Facebook's claim that the definition of news was so broad to as to include the official government pages.
"We don't accept that interpretation of the definition of news. It's very clear in the legislation it doesn't apply to government information," he said.
Thursday's events confirmed the immense market power of the media digital giants, the Treasurer said.
"Many Australians rely on Facebook for their information, information that may be very important, credible information about government services," he said.
"It does show you how integral they are to the provision of news."
The inclusion of pages by public health bodies and charities shocked Health Minister Greg Hunt, noting that ACT Health, Queensland Health, South Australia Health, Dementia Australia, the Kids Cancer Project, and Bowel Cancer Australia were all affected.
"The fact that the Kids Cancer Project could be effected is frankly a disgrace," Mr Hunt said.
Communications Minister Paul Fletcher spoke to Facebook on Thursday morning after the news and government pages were banned.
"We're very clear on the proposition that we're going to legislate the code," Mr Fletcher said.
"We have been talking to stakeholders all the way through, including Google and Facebook, and we'll continue to do that."
