Tasmanian devils wipe out thousands of penguins on tiny Australian island:
An attempt to save the Tasmanian devil by shipping an "insurance population" to a tiny Australian island has come at a "catastrophic" cost to the birdlife there, including the complete elimination of little penguins, according to BirdLife Tasmania.
Maria Island, a 116-square-kilometre island east of Tasmania, was home to 3,000 breeding pairs of little penguins around a decade ago.
Their populations have dwindled since Tasmanian devils were introduced in 2012, but according to BirdLife Tasmania, the most recent survey conducted by the parks department showed penguins had completely disappeared from the island.

Every time we humans meddle, Nature pays a price. Not the first rodeo for Oz though - they and the Kiwis have a long record of eco-mishaps. Rabbits, stoats, (feral) cats, possums. Introducing a predator for a pest, which goes on to wipe out several other species - this is BAU (business as usual) for AU/NZ. Its the standard "She'll be right." followed by "Oh oops, we didn't see that coming." You can bet the eco-experts who advised on this all got 6 figure incomes...

Of course, all those mistakes are predicated on the first mistake: Letting the fucking Brits in!

The "native" aborigines wiped out the large marsupials when they arrived, leaving only smaller animals for the Brits to inadvertently kill.

Sounds good - but demonstrably not true. For example, locally to me, consider the reintroduction of the red kite into UK which has been a huge success with currently hundreds of breeding pairs.

Is it really so surprising that reintroducing a species didn't cause problems? The ecosystem had already evolved to support them there.
Versus introducing a species into an area it's not native to, then it has no local competitors and goes crazy.

It wasn't really re-introduction in the case of Maria island (pronounce Mor-i-ah). There were never devils there before (the island is too small to have a sustainable population). The devils on Maria are human raised rescue animals. They have different behaviors than wild devils, e.g., they are much more social with members of their own species (female with young will allow males in burrow-- not seen anywhere else AFAIK) as well as less reclusive.
Maria island is an amazing place to bring the family to be certain to see wildlife in a setting that is not oppressive like a zoo. Essentially, a large free range zoo. Wombats are nearly tame, and come out during the day (normally nocturnal). Free camping too (7km from the ferry landing IIRC), so just need to pay the round trip ferry fare. Or, cheap camping close to the landing.
It is a former prison island. The cells have been converted into hotel rooms if camping is not your thing.
As for the devils, Moria has cancer free devils. There aren't many of those left, since the cancers they have are transmissible.

> Rabbits
Introduced to Aus & NZ by idiot rich people so they could hunt them
> stoats
Introduced to Aus & NZ, against the advice of scientists & naturalists, by idiot politicians to control the rabbits. A pest now in NZ, but never successfully established in Australia.
> (feral) cats
Introduced to Australia & NZ, initially as ship's cats and later by rich free settlers as pets.
> possums
Native to most of Australia. Introduced to NZ from Australia by businessmen to develop a fur trade.
Seems the historical examples in your rant don't really have much to do with this particular situation...

FWIW, the Tasmanian DPI did predict this outcome before the devils were introduced there. But Little Penguins are almost ubiquitous around the coast of Tasmania & southern Australia and their IUCN status is "Least Concern". Maria Island also already had a number of other local introduced species (pademelons, wallabies, and roos) that were effectively 'pests' there, and it was felt at the time that the risk to a small penguin population was outweighed by the much larger risk that Devil Facial Tumour Disease posed to the whole of the devil population.
