SEQUEST is a program that was established in 2021 by Marine Society UQ. The aim was to enable a more detailed understanding of marine invertebrate communities and provide a vital early warning system of changes and threats (e.g. invasive species) to Quandamooka (Moreton Bay). Using Autonomous Reef Monitoring Structures (ARMS), which are horizontal stacks of settlement plates, we could monitor marine invertebrate recruitment and diversity within communities. Four ARMS devices were placed in two different ecosystems in Quandamooka (Moreton Bay, QLD); (1) Manly Marina (highly disturbed) and (2) Minjerribah (minimal disturbance). From two years of monitoring the settlement plates, the more oceanic site near Minjerribah was dominated by urochordates (32%), followed by arthropods (20%) and annelids (12%) in our observations (n=93). While our observations at the marina (n = 396) were dominated by arthropods (34%), annelids (19%) and urochordates (17%). Some of the least common phyla observed at the Minjerribah and marina sites included Porifera (3% and 2% respectively) and Echinodermata (5% and 0.3% respectively). These findings, along with the detection of the invasive tunicate, Symplegma brakenhielmi, demonstrate SEQUEST’s ability to provide Bay custodians with data on the health of the Bay while upskilling SEQUEST’s dedicated volunteer scientists.
