Planned extinction: Is it ethical to deliberately wipe out a species?

Now there's a war of attrition.

It's suspected that the Rabbit is the single greatest factor in the extinction of native species since European colonization in Australia; bigger then humans, or even feral cats/dogs/foxes. The land damage they've caused through erosion is projected to take centuries to repair.

Here down under we've delibrately introduced not one but two foreign viruses to try to wipe them out; first Myxoma in 1950, then Calici in the 90s. Both brought numbers plummetting down for a while, until they acquired a resistance and rebounded.

Hell, we even built the world's longest fence to try to contain them; 3256km.

Their extermination at least from the continent would be hugely beneficial to most other living things there, including people.

That's one of the thigns we learned from HIV/AIDS treatments.  You always need 3.  Even if the 3rd one is only like 60% effective. 

Plus now half of the bunnies are immute to Myxoma.  So it's not so effective anymore.

I do know they were releasing something very recently in Sidney - from a bunny list.  So maybe there is something new going out.  Rabbit should only be indoor pets in Australia - not pest.

Or they could make tiny bunny killing robots.  They also need to do that with the monguses in Hawaii.  Similar devistation.
