So with only half of our total population currently receiving fluoridated water, there's certainly potential for us to get some really significant public health gains. My colleague Matt Doocey talked a little bit about the cost benefit of this. I note that having water fluoridated over 20 years is likely to save the Government around $600 million in savings through reduced need for dental treatment, and this will be versus the cost of extending the fluoridation at $144 million over that same 20-year period. I would think that local government might want to have a talk to the Government about why they're doing the spending and Government's doing the saving.
