One of the Library of Australian Authors series. 'Shape-shifter aliens establish bases in wilderness areas of Earth, including north-west Australia ... While exploring the Kimberleys, two English youths stumble upon a plot by the aliens to destroy humanity through the breeding of new forms of plague. At first the conspirators appear to be merely members of some secret society, but it is soon revealed that they are nothing less than devils from outer space' ('Strange Constellations. A History of Australian Science Fiction').
