 This might be a good example of never learning the lesson. In
conservation, 'management' there seems to be a history of muddling through
introductions of species to particular habitats (usually islands) without
due consideration of the impact on other organisms. New Zealand
conservation has a 'good' historical record of this. I guess it's no
surprise to see that Australia follows suit.
