If a particular indsutry lacks comparative advantage in some country (in this case Australia) it only stands to reason that others do have comparative advantage in it.

So you we can speculate why, in a complicated world, the (cars, Australia) paring works badly while the (education, Australia) and (cars, [South!] Korea) pairings work well and the (cars, Taiwan) paring is somewhere in between.

But an important answer behind all of these is: The market speaketh thus.
