The story of the Sisters Boo'kerrikin and how to distinguish between local wattle plants, by artist Joe Hurst.

This artwork depicts the D’harawal story of the man called 'Bulung', represented by the central rock, who devoted his life to finding the physical difference between the Wattle Sisters, represented by the three pillars.  All his attempts, however, failed. The secret of the Sisters' difference is told in the ceramic tiles around the pillars.
