Australia's acting prime minister Michael McCormack has blasted social media giants for kicking Donald Trump off their platforms.
Treasurer Josh Frydenberg has also voiced his discomfort, raising concerns about freedom of speech.
The US president has been removed from Twitter, Facebook and Instagram after posting messages the technology giants said could encourage violence, following an insurrection by a mob of his supporters.
Asked if Mr Trump helped incite a riot at the US Capitol on January 6, Mr McCormack said the president's social media comments were unfortunate, as was his refusal to accept the outcome of the US election.
But Mr McCormack also likened the riot to Black Lives Matter protests last year and said it should not be up to Big Tech to decide whose voices were heard.
"I don't believe in that sort of censorship," he told ABC radio on Monday.
"There's been a lot of people who have said and done a lot of things on Twitter previously that haven't received that sort of condemnation or indeed censorship."
However, the acting prime minister acknowledged social media companies were within their rights to close accounts.
"That's a matter for Twitter, they've made that call, they've got a company, they've got a business to run, and they've made that decision," he said.
The treasurer said he felt "pretty uncomfortable" about the action taken against Mr Trump.
"Freedom of speech is fundamental to our society. As Voltaire said, 'I may not agree with what you say, but I defend your right to say it'," Mr Frydenberg told reporters.
"Those decisions were taken by commercial companies, but personally, I felt uncomfortable with what they did."
Australia's competition watchdog has called for clearer rules to determine what content is acceptable on social media.
Queensland MP George Christensen is among several federal government backbenchers using social media to peddle misinformation being spread by supporters of Mr Trump.
But Mr Frydenberg, a senior member of the leadership team, refused to censure him.
"George Christensen will make decisions he is accountable for."
Mr Frydenberg said the prime minister spoke for the government and the whole country in expressing disgust about the storming and ransacking of Congress in Washington DC.
Opposition Leader Anthony Albanese called on the prime minister to condemn Mr Christensen and his coalition colleague Craig Kelly, who has also been spreading discredited conspiracy theories about the riot.
Mr Albanese defended social media companies shutting down Mr Trump's accounts.
"It's about time that people weren't given a platform to spread hatred, to spread lies," he told Sydney radio 2SM.
Mr McCormack would not be drawn on whether Mr Trump should be removed from office before his term ends on January 20.
But he did apply a distinctly Australian lens to the "unfortunate events" at Capitol Hill and the dying days of the Trump presidency.
"Many people don't remember how you rode the horse, they remember how you dismount the horse," Mr McCormack said.
