This is the main Papuan biodome that is the central highlight of the indoor section, though sadly barely have any signage indicating what species are held here.
From my last tour, the animals I saw were;
Hypsilurus godeffroyi
Tiliqua gigas evanescens
Carettochelys insculpta
Chelodina novaeguinae
Elseya novaeguinae
Emydura subglobosa
Datnoides campbelli
Melanotaenia boesemani
They also have lophosaurus dilophus and Australian green tree frog that are well-hidden within the biotope.
