A path along the foreshore and up to the rotunda contains bricks engraved with dedications and messages from local people. This was definitely my favourite.
The artwork is in the shape the footpad of the Tachyglossus, a now-extinct relative of the echidna. It includes totems of the local Gulidjan/Kolacgnat tribe as well as a boomerang, a gum tree leaf and an outline of Red Rock, a dormant volcano visible on the other side of the lake. It is surrounded by native grasses and plants, and a stone wall that represents British settlement.
