I had a look through the SMH articles. The Koala extinction one is a bit of a play on words and play on hearts. It doesn't actually say they are facing extinction as a species. It says that they are driven toward extinction sooner, and that they have a chance of becoming extinct in NSW. It's a bit of a play on words as most people hear "extinction" and think that means the end of the entire species. So SMH have played on that emotional misunderstanding. Extinction can just mean the end of a family or the end of a group (for example, NSW Koalas). That's possible, but it's unlikely that all Koalas would go extinct. That said, people often think that Koalas are Australia wide. But they're actually only east coast creatures. Stretching from the middle of Queensland coast down to Victoria. Still unlikely to go extinct but it's a massive loss of the species.
