About This Quiz

For too long, the marsupials have captivated the attention of Australian wildlife enthusiasts. Sure, koalas are as cute as a bug’s ear and everyone has secretly wanted to try boxing a kangaroo, but have you ever looked in the rivers, lakes and oceans around Australia? They’re positively teeming with unique wildlife. Some of it is small and unassuming, some of it is massive and dangerous. With over 5,000 species of fish, there’s plenty to go around.

Australia’s uniqueness is present as much in its waterways as it is on the land. Some species have been introduced from far away, like rainbow trout, but many species of fish can only be found in Australia, like the blind cave gudgeon. Surrounded on all sides by oceans, it has some of the most remarkable marine species in the world, too. If you want to catch the best champion giant black marlin, you do it in Australia!

So do you think you know the difference between a barramundi and a bullrout? Can you identify an Empire gudgeon at 50 paces? Is there any chance you’d not know an un-speckled hardyhead when you saw one? If you think you have what it takes, dive in and take the test!
