I think a few people should just do some basic cane toad searches in Google scholar, the results will answer most of the questions that have been asked. As well as explain the basics of ecology and toads, and how the biggest killer of cane toads is cane toads(have a look into cane toad survival rates). It is worth noting that to date nothing has gone extinct due to cane toads, there are much bigger threats - cats and foxes - have a look into the small mammals and critical weight range, or just look in the Australian mammal field guide and look at how many species previous range compares to current range. Or just note that Australia has the highest mammal extinction rate in the world.
Back to toads, everyone wants to do something about them, but lets be completely honest we can't. toads are here, there spreading and all we can do is slow them. When they hit the kimberleys there will be massive declines in frog eating species. will anything go extinct? wait and see. The government spent millions trying to develop methods to get rid of them, and realized it was going nowhere and stopped. Toads have decimated wildlife populations but animals are adapting, e.g. birds flip toads over, crocodiles have been seen to "wash" them before eating, snake head size has apparently changed (there is a paper on this).
There is nothing we can do now but watch them slowly march across the country
