NICOLA WILLIS (National): In rising to offer the final contribution in this debate, I'm reminded of that reality, which is that we politicians in this House do an important job but we would be absolutely nowhere without the highly informed and educated officials and public servants behind us who do much of the detailed, difficult work on bills like this and do so with a level of expertise that is, as I think it is fair to say, and with all due respect to all of my colleagues, to a level that is beyond the comprehension of anyone who's contributed to this debate.
