Press freedom might be important to Australia's prime minister in China, but it's an inconvenience back home.

That's the view of News Corp Australia group executive corporate affairs, policy and government relations Campbell Reid, following a police raid on the home of a former senior government adviser.

"We have always said the AFP raids on journalists were not intended to intimidate journalists but the people who have the courage to talk to journalists," he said. "Today we are seeing that process of intimidation continue."

The AFP raid on the Canberra home of Cameron Gill follows raids on News Corp and ABC journalists. Gill was a senior adviser to former Liberal MP Mal Brough when he was minister for defence matériel and science in 2015. News' national daily The Australian also said it had established that he was married to Australia's ambassador to Iraq, Joanne Loundes. It said the AFP had refused to confirm that the raid on the Griffith home was connected with the raids made on journalists.

Last week Campbell Reid accused Australian prime minister Scott Morrison of hypocrisy over expressed over writer Yang Hengjun's incarceration in China but not with press freedom at home. "I saw Mr Morrison in front of the microphones talking very compellingly about the predicament the Australian writer in China is in. Under arrest, accused of espionage; so I ask this question: Why is press freedom very important, and freedom of information important in China, and not very important in Australia?" Reid asked at an Alliance for Journalists Freedom Summit.
