Dr. Karin Denton:

Australia went from a decision to implement to implementation in about 12 months. I would have to check the exact duration but it was of that order. The UK, or England at any rate, will probably take approximately 18 months. Scotland and Wales will be somewhat quicker.

Obviously, we are not starting at the point of making a decision. A decision has already been made and I think that implementation within 12 months is achievable.
