I actually know intimately well the importance of biosecurity. I had M. bovis on farm, and I think most of you are acutely aware of it. It was pretty much the most heartbreaking part of my farming career—I've been farming for 30 years, which I often share with this House—and it was the hardest 18 months of my farming life. It absolutely devastated me, the local community, and I think we would share in the concern of what M. bovis has meant to the country. It's a billion dollars; it's an absolute rort on my small community, and all of the 50-odd farms that were involved in it.
