Today, I learned that Australia is a land mass that broke off of Antarctica. As a result, it didn't have robust fauna or earthworm ecosystems, so it doesn't have millions of years of soil compaction....
Summary
Australia's extreme venom prevalence in both land and marine animals results from its geographic isolation after breaking off from Antarctica 35-40 million years ago, allowing venomous elapid snakes to monopolize ecological niches without competition from non-venomous species, while its arid, nutrient-poor environment created selective pressure for instant-kill venom as predators and prey evolved in an intense arms race.
