The second point is the increase in meth out in the communities. We know that the growth of meth in the communities is sky-rocketing, and we can't expect it not to have an impact on what is going on in prisons because we know that 90 percent of people in prisons, over the course of their lives, have a drug and alcohol or a mental health issue. So for those people who are on meth out in the communities, that will also flow on into their behaviour in prisons and it impacts on the way they behave there.
