Thank you.
I guess the information I want to extract here is more a comparison across time. Basically we're here because of a policy decision in 1972. Then there was the voluntary moratorium in 1988. Now we're in 2017. As I was saying, the information I want to extract is whether the risks have changed and if we've adapted to those risks.
I'll start with the enforcement side, the Department of the Environment. Over the years, from 1972 to now, are there particular types of offenders that are repeat offenders, or have you seen something changing over the years?
