Mr President, I ask a supplementary question. I refer to a common scenario, given by Associate Professor Owler, of patients on the anti-clotting medication warfarin who may not always fall under the 10-visit concession cap. Associate Professor Owler says that when patients go on warfarin they usually need a large number of visits to determine whether their blood is too thin or thin enough for this treatment. Isn't it true that with a $7 GP tax this could add up to hundreds of dollars for this life-saving treatment?
