Hinchinbrook Island - Cane Toads

I have just come back from completing this walk with some friends and one thing that suprised me was that there were a large number of Cane Toads on the island especially around Zoe Bay. Must have seen at least 20 of these just on the track between the falls and the campsite which was a bit suprising. Could really do some damage to the island over the next few years which is really sad.
I took a photo of one which I will post up here later but was wondering if anyone else has experienced this, if it has been reported anywhere and if anything is being done about it (I don't think anything can be done)? It doesn't sound like they have been there for very long as people I have spoken to about it were un aware that they were there.
