A News Corp employee has accused the organisation of a "misinformation campaign" filled with "irresponsible" and "dangerous" coverage of the national bushfire crisis, urging executive chairman Michael Miller to think about the "big picture".

In an email distributed to News Corp Australia staff and addressed to Mr Miller, commercial finance manager Emily Townsend said she had been filled with anxiety and disappointment over the coverage, which had impacted her ability to work.

Ms Townsend, who has worked for News Corp Australia for five years, thanked Mr Miller for the email about fundraising initiatives in relation to the fires, but said the efforts did not offset the company's coverage of the bushfires.

"I have been severely impacted by the coverage of News Corp publications in relation to the fires, in particular the misinformation campaign that has tried to divert attention away from the real issue which is climate change to rather focus on arson (including misrepresenting facts)," she said.
