Do you know of any interesting or little known introduced populations? Here are some I know of:

  • Greater Rheas in Germany
  • Red-Necked Wallabies in Ireland
  • Beech Martens in Wisconsin
  • Mariana Swiftlets in Hawaii
  • Electric Eels in Flordia
  • Siamese Fighting Fish in Australia
  • Various US birds not on the ABA list (Red-Vented Bulbul, Great Tit, European Goldfinch, Greylag Goose, Swan Goose, Black Swan, Pin-Tailed Whydah, Orange-Cheeked Waxbill, ect.)
 
There are wallabies in quite a few places in the UK namely the Peak District and the Isle of Wight. I think there are even more too.

Wrong on both accounts; the Peak District population died off some time ago now (the final two females were last seen in 2003 and 2009 respectively, and the last male before the turn of the century) and there has never been a feral population on the Isle of Wight. I believe you intended to say the Isle of Man, which does have a substantial population.

There is also a large population in the Scottish Highlands, on the shores of Loch Lomond and two of the larger islands within the loch, along with smaller populations in Devon and Bedfordshire.

Are you able to reveal the location of the Devon wallabies?

It was a friend that told me it was the Isle of Wight so they must have misheard.

I don't know the precise location I'm afraid - I recall reading about them in a paper largely focused on the decline of the Peak population, but for the life of me I cannot remember where the aforementioned paper was published in order to check whether the Devon location was directly stated.
 
Do you know where the Siamese Fighting fish are located? I know of several water ways around Brisbane with Black Pacu, although not established Black Pacu can live for over 20 years so there not going anywhere anytime soon...

Wikipedia said:
In January 2014 a large population of the fish was discovered in the Adelaide River Floodplain in the Northern Territory, Australia. As an invasive species they pose a threat to native fish, frogs and other wetland wildlife.

There's a place called Robin Hill on the IOW that used to have animals- they had a number of escapes including Prairie Dogs that established themselves on the Downs outside the zoo boundary, and also Fallow Deer that established for a while until they were culled. They had Wallabies too and its quite possible some of those escaped also, though a feral population is not there now, nor the Prairie Dogs afaik. Robin Hill is now an adventure park and most(all?) animals have long gone.
 
No-one mentioning parrots? There's quite a few populations in Europe, including the (in)famous Kingston parakeets. And I think Spain has at least five species including nanday(?) conures.
