I remember when I was growing up in QLD the amount of Cane Toads that were there, you'd get at least 20 Cane toads in your yard every night, and that was 15yrs ago. As much as I love Frogs and Toads, and wish it were different, I totally understand this culling. As an introduced species, it's not only a danger to the native Frogs (either by eating them, or competing for food), but to native birds and reptiles if they try to eat them.
