I've been wondering lately how and whether Australia could use its position as the biggest exporter to deliberately wreck the global thermal coal market, and consequently, coal usage.

I'm definitely not an economist, but would it be feasible, if coal production could be co-ordinated nationally, to manipulate the market through (I'm guessing) either or alternately dumping coal on it or suddenly cutting it off, possibly in an unpredictable manner? Does Australia have enough weight to make a difference? And would this have any effect greater than cutting off production entirely?
