This features a rock wall and small waterfall. A length of miniature train track runs through a fence opposite this aviary and up to the concrete block structure described earlier. This marks an earlier course of the miniature train line. The Spirit of the Outback store (former Rock Shop) is founded on a concrete slab with a sloping skirt around the entire building and expressed columns at each wall joint, which hide the downpipes. These consist of a concrete casing. It has a hipped roof clad in corrugated steel and walls faced with stone. Its wide fascia panels and eaves are lined with fibrous-cement sheeting. Inside there is a cathedral ceiling with fibrous-cement sheeting behind narrow timber rafters. The walls are also lined with fibrous-cement sheeting. A south-facing doorway in the former Rock Shop allows visitors into the sanctuary. To the immediate east of this doorway stands the annex built in 1965 to a rectangular plan but with similar materials. To the south-west of this is situated the main train station platform. To the south is the landing of an elevated timber walkway leading into the south-eastern corner of the site and then into the Green Cauldron enclosure, which sits near the site's southern boundary and incorporates at least two earlier building phases carried out after the early 1980s. The Green Guardian Theatre building (1990) sits between this structure and the main train platform. The last four structures are not considered of significance. In the south-eastern corner of the site, visible only to visitors on the walkway, is a fibrous-cement clad building, likely to be one of the oldest structures on the site. It is octagonal in plan and has a concertinaed, hip and valley roof made with flat fibrous-cement sheets and barge boards individual to each roof face. Its walls are similarly clad. It has a number of aluminium-framed, sliding windows. The timber walkway area is shaded by a number of mature trees, which shelter this structure from potentially damaging hail and wind. It sits behind a high chain-wire and thatched fence. To the west the site is bounded by a wide avenue of paving beside a screen of paperbarks (Melaleuca sp.) and gum trees (Eucalyptus sp.) lining the lorikeet habitat of Flat Rock Creek. Between it and the lorikeet-feeding arena are a number of enclosures housing koalas. To the east is the entrance to the Green Guardian Theatre (1990).
