pohm, did said QF aircraft give an inbound report? Did they give indications as to their tracking? Did you know where they were or where they'd come from?
Whilst on the one hand I can see the point of calling it a bonehead report if you don't know where they are but I'd be surprised if that was the only information broadcast. I suspect that you'd probably know what their general heading was and roughly where they were coming from so them referring to you in their 11 perhaps gives more clues than it appears from your tale. Perhaps your own SA could also do with a bit of work?
Of course, there remains the possibility that the crew also thought 'doh' immediately after saying that too.
