The management of water quality remains an essential requirement to ensure the long-term protection of the coastal and inshore ecosystems of the Great Barrier Reef (GBR) (Commonwealth of Australia, 2015). The land management initiatives under the Australian and Queensland Government's Reef Water Quality Protection Plan (Reef Plan) and the Reef 2050 Long Term Sustainability Plan (Reef 2050 Plan) are key actions to improve the water quality entering the Great Barrier Reef. The goal of Reef Plan is “To ensure that by 2020 the quality of water entering the reef from broadscale land use has no detrimental impact on the health and resilience of the Great Barrier Reef.” The purpose of this report was to conduct a rapid and preliminary review of the Marine Water Quality Metric presented in the 2015-16 Reef Plan Report Card, focusing on issues highlighted by the Reef Plan ISP associated with data confidence of remotely sensed data in inshore areas
