@That Aussie Guy Has been variously on and off display over the past half a decade or so. I saw it on my 2021 visit to the zoo but missed it on my 2023 visit.
@WhistlingKite24 I believe the Common Snapping Turtle was housed in the tank to the left of the large indoor saltwater crocodile enclosure for "Crunch" when I went to visit, which also housed Alligator Snapping Turtles
