The Academy urges State and Federal governments to combine forces to provide immediately all the resources necessary to combat this threat and eliminate the introduced population. The lessons from past introductions of pests to Australia and other parts of the world show clearly that a delay of even a few months will dramatically increase the scale of the problem and the cost of any remedy. Control carried out now, before the breeding season begins in July, will be many times more effective than controls done subsequently. Any longer delay may render the problem insoluble, and condemn more of our charismatic fauna to extinction.’
