Oh,and veterans of the Armed Forces.Didn't Nopalitano once classify vets as being potential terrorists?
The problem is this whole thing was mishandled. The ban should have explicitly been on all forms of face coverings with no exceptions - but it wasn’t. It was specifically on religious headcoverings. This would almost made it both unconstitutional under Section 116 of the Constitution, as well as violating anti-discrimination laws. So it could not be allowed to stand.
Now, if there are any security issues of real concern, the appropriate authorities (the Australian Federal Police) are free to reintroduce restrictions that clearly do not reference religion (such as ‘no covering of the face under any circumstances’) in a way that will pass constitutional muster, and legal muster. As it was, the restrictions put in place prevented that happening, and would have almost certainly been struck down by the High Court anyway.
