Monitoring and Reporting (Port Phillip Bay)

Monitoring and reporting for marine water quality in Port Phillip Bay

The current condition of marine water in Port Phillip Bay has been assessed (Method and Condition) and targets have been set for the future (Targets). Lead organisations are committed to achieving these targets (Leadership) and the main pressures have been identified (Pressures).

This section outlines the monitoring that will be undertaken to check progress towards the targets and how progress will be reported.


The Environment Protection Authority regularly collects water quality data for Port Phillip Bay and maintains a database of the results.

Each year, this data is used to re-assess the condition of marine water by comparing the results to the objectives in the relevant State environmental protection policy.


The condition of marine water will be reported on as part of a ‘catchment condition’ report produced every three years by the Port Phillip & Westernport Catchment Management Authority. The report will include discussion of the following questions:

  • Is adequate data being collected to enable monitoring and reporting of progress towards the targets?
  • Has the condition of the marine water changed?
  • Are we likely to meet the targets?  If not, what changes are needed so it becomes likely the targets will be met?  Or do the targets need to be revised?
  • Does this target provide sufficient indication of the overall ecological health and resilience of marine environments?  If not, what changes are needed?
