Ms Buttrose raised concerns about the raids on the ABC's headquarters and a News Corp journalist's home in a conversation with the new Communications Minister.
Search warrants were executed at the A-B-C's Ultimo headquarters over 2017 stories on allegations Australian soldiers may have carried out unlawful killings in Afghanistan, based on leaked Defence papers.
Another warrant executed on News Corp journalist Annika Smethurst's home was over the 2018 publication of a leaked plan to allow the Australian Signals Directorate to spy on Australians.
