Sky News Australia has removed dozens of videos from its websites, after YouTube suspended the channel for spreading Covid misinformation.
In recent days it has taken down about 30 videos without explanation or making corrections.
Sky News Australia has declined to comment.
But its parent company, News Corp Australia, told local media the network had taken an "editorial decision" to remove the videos.
It comes as millions of Australians remain in lockdown to prevent the spread of Delta outbreaks in Sydney and Melbourne.
Fewer than a quarter of Australians are vaccinated. Frustration over restrictions has also led to several large anti-lockdown protests.
