This is the list I have: Olive Python Woma Python Jungle Python Inland Taipan Eastern Brown Snake Mulga Snake Coastal Taipan Brown Tree Snake Blue-tongued Lizard Snapping Turtle Saw-shelled Turtle Magnificent Green Treefrog Tarantulas Red-backed Spider* Scorpions Millipedes* Spiny Leaf Insect And mind you that might not even be correct. Signage was largely wrong, non-existent or unspecific, and there was a couple of tanks you couldn't see into properly.
The top ten most venomous snakes were a kind of target species for me during my trip in Australia, but all listed species I've seen elsewere.
