Port Macquarie is one airport that springs to mind where this situation exists quite often, with turboprops/jets landing 03, mixing it with circuit traffic on 21. It is however fairly easy to resolve if you just talk to the other person!
It is also easier if you are able to conduct a straight in approach, that way you can keep the other aircraft in view at all times. Otherwise, position yourself to join downwind as the other aircraft touches down, then conduct a normal circuit, if it gets tight ask the other aircraft to extend on downwind. You will more than likley find that this can be completed without either aircraft being hindered.
Disclaimer: Of course this technique will not work if one runway has RH circuits!
