On the right (of the photo) would be the Common Wombat (Vombatus ursinus) and on the other side would be Red-legged Pademelons (Thylogale stigmatica). However the wombat had been temporarily moved to another facility to avoid stress from nearby construction work, and it seems like the pademelons haven't been here for some time.
This boardwalk is at the beginning of the walk-through kangaroo enclosure. In the back can be seen the door out of the indoor section where all the terrariums are, and indeed some of the tanks can be seen through the window (the row of three which are visible, from right to left in the photo, are for crocodile, frogs, and Red-bellied Black Snake).
