This is patently not the 'controller was separating the aircraft as if they were both IFR'.
So why the right hand turn???
My understanding is, in E, ATC provides separation to IFR and advisory on VFR. So by turning the Cessna s/he had 'taken control' and on that basis I can only assume was providing IFR/IFR separation.
Now I have absolutely no problems with that, that is the 'culture' everyone says we don't have in Oz. It is just that if it is true, then it is not a breakdown of NAS.
