Monitoring and reporting of marine water quality for Western Port

The current quality of marine water in Western Port 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 undertakes regular water quality monitoring in Western Port and maintains a database of results.

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


The water quality in Western Port will be reported on as part of a ‘catchment condition’ report produced every 3 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 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 the target provide sufficient indication of the overall ecological health and resilience of marine environments? If not, what changes are needed?
