In London/UK the tourist board operate a "Blue Badge" scheme for tour guides. This means that they have sat exams and past vetting procedures to do their job. You know that they know their subject and you are going to get a good tour.
Is there a similar scheme in Australian cities ?
Thanks, planning a short tour soon and want to cram a lot of good stuff in.
