looking at earlier photos in the gallery, the Reptile House was a few years ago displaying a theme of deadliest snakes.
The current line-up, if coming in from the entrance at the left of this shot:
1) Mixed tank for baby Freshwater Crocodile, Merten's Water Monitor, Eastern Water Dragon, and Northern Snakeneck (C. rugosa).
2) Spiny-tailed Monitor and Centralian Blue-tongue Skink. (This is the first tank visible on the left of this photo).
3) Red-bellied Black Snake.
4) Boyd's Forest Dragon and Green Tree Frog.
5) Mainland Tiger Snake.
6) Australian Scrub Python, Jungle Carpet Python, and Land Mullet.
7) Frilled Lizard and Major Skink.
8) Green Tree Snake.
9) Black-headed Python.
10) Central Bearded Dragon and Stumptail Skink.
At the far end of the house is another room where there is a viewing window to off-show tanks. At the front of the window are a few small display tanks though, for Burton's Legless Lizard, Guthega Skink, and (presumably usually there, but not on my visit) Alpine She-Oak Skink.
All the main tanks have annoying revolving electronic signage.
There are some other herptile species displayed elsewhere in the park as well.
