The vertical reference level for each standard port is the port datum. Since 1994, this datum was set to the lowest astronomical tide (LAT) at Queensland ports. To define this datum a tide gauge benchmark (TGBM) is established. The height of this benchmark, relative to LAT, is then used to define the port datum onsite.
