The most interesting animals in Australia are the ones that have evolved to fill the very specific niches available on the once-isolated continent. The introduction of new species during European colonization brought animals that weren't so well adjusted, and have strained the local environment to keep up. Domestic cattle, for instance, have been fouling fields because the local dung beetle population simply can't cope with that much cow crap. This has forced scientists to look elsewhere for a solution.
