Shellfish reefs in Moreton Bay play an essential role in maintaining coastal ecosystem health and hold cultural significance in Australia. For thousands of years, Traditional Owners have sustainably harvested shellfish, leaving behind oyster middens that still shape the coastal landscape. European colonists later exploited these oyster reefs for lime production, leading to overharvesting and ecosystem collapse. Today, only 1-4% of Australia’s original shellfish reefs remain, victims of dredging, disease, sedimentation, and degraded water quality.
