"In effect, this is the head of our security apparatus ringing up saying, 'Senator, I don't like you commenting the way you did'," he told AAP.
"He is paid well, he is not a coward in any way shape or form, he is a pretty tough guy.
"Maybe some other politician, who wasn't a former submariner, might be inclined to back off, but I don't."

Mr Pezzullo strongly denies the crossbencher's accusation.
"My sole request made to him by telephone was to ask that he reflect on his adverse references to my purported view of media scrutiny," Mr Pezzullo told the ABC.
"His comments were unfounded and not able to be responded to by me in the media as quite properly I lack the public platform that he has, and uses."
