A new self-guided walk, funded by the Friends, was launched on January 21st 2016 by Ngunnawal elder, Aunty Agnes Shea and Barbara Podger, chair of the Friends' Public Fund. The event was reported by ABC News.

The trail features 27 plants important to Indigenous people, ranging from the coastal native raspberry (Rubus moluccanus) to the quandong (Santalum acuminatum) found in the drier Australian interior. The Aboriginal Plant Use trail winds through the Rainforest Gully, Conifer Garden, Rock Garden and Monocot Garden with interpretive signs telling how Aboriginal people used each of the featured plants.
