The track may be compliant with a particular standard, but not to the standard required to host an event for the likes of Supercars (Grade 3), or any catagory that sits at the same tier as Supercars, in the eyes of the FIA.
If the track is no longer FIA Grade 3-compliant, CAMS are not obligated to issue the required licences to Supercars, or the likes of The Nationals.
