This document is the first annual monitoring report of the Pressure Monitoring sub-program of the Darwin Harbour Integrated Marine Monitoring and Research Program (IMMRP). It reports on trends and other relationships in the time series of a range of pressure indicators previously identified as relevant to Darwin Harbour. The indicators correspond to key aspects of catchment condition including land-use, stormwater pollutant loads, fire regime and waste disposal, marine pressures including shipping activity and biological harvesting and the underpinning drivers behind the pressures including human population and economic development. Several of the indicators had increasing trends that were statistically significant over the time periods of measurement including population size and gross regional product (2000-01 to 2019-20), fire frequencies in most western sub-catchments (2000 to 2020) and point-source loads of total nitrogen to the Inner Harbour (2011-12 to 2018-19).,
