anti discrimination act is what actually faciltates unfair dismissal laws, thus though they are both relevant it is the unfair dismissal laws which protect workers in this case as it provides redress, thnk of it like this... if we did not have unfair dismissal laws you couldn't really do anything to stop employers dismissing on the basis of physical disabilty etc, as although anti discrimination laws would make it illegal there would be no way to punish employers, or get the workers job reinstated, thus workers are only protected with unfair dismissal laws in place.
