Australia, 1988. Aboriginal art.
That design I find interesting; maybe because it's quite different from the others.

As for kangaroos/wallabies in Europe, well, of course you can find them in zoos. Apart from that (let me quote from the Polish central bank's brochure), "In Europe, feral or stray Bennett's wallabies (usually from private and public zoos) make up a constant though small population in Great Britain (the oldest groups derive from the wallabies that strayed in 1920). A group of approximately 30 kangaroos lives in the wild 50 km west of Paris – they are the descendants of wallabies from one of the zoos, that escaped after a hurricane in the 1970s."
So maybe it would have made more sense for the Royal Mint and the Monnaie de Paris to get involved in that common issue. Ah well, the two shown in the initial post are for collectors only anyway. Most of the other pieces may actually occur (or have occurred) in the wild.
