In an interview on ABC's 7:30 program Tuesday night he said that Abu Bakr-al Baghdadi's name was an "operational matter". But as Leigh Sales points out in the interview, it's really not.
In fact, the man Kevin Andrews refused to name is so well known, the United States has a $10 million bounty on his head.
Sales pointed out to Andrews that it's pretty worrying that he couldn't say the name of the ISIS leader, given that he's "responsible for putting Australian men and women in harm's way."
The defence minister said he couldn't name the leader because ISIS is made up of "a combination of groups".
"It's not just one person involved, there's a series of people involved and we must ultimately destroy all of them if we're going to degrade their operations in that area." he said.
