Trash 'N' Navs..
You can probably learn as much about the NAFC from the net as you can from me. Pity that their website seems to be 12 months behind. Maybe that tells us something.
My limited info is that it's essentially a committee of the various state departmental heads who determine how the Federally funded contract aircraft are to be used. There's obviously some sense in having a Federally funded asset with a flexible deployment so that aircraft can be allocated according to need, rather than just according to state boundaries. But it's also true that when one part of SE Australia has a bad fire seaon, it tends to be across state boundaries.
A better source for current research into the effectiveness of the various systems would be the Bushfire CRC.
