Notice to mariners

A Notice to Mariners (NtM) reports maritime safety information on Northern Territory (NT) waters.

This includes:

  • closed waters (exclusion zones)
  • new hydrographic information
  • changes in channel depths
  • aids to navigation.

They're shared to mariners (recreational and commercial) and maritime-related organisations.

Marine operators are also required by law to report navigational hazards or dangers.

Types of notices

A notice can appear as a:

  • permanent notice - changes to information which result in a chart correction released by the Australian Hydrographic Service
  • preliminary notice (P) - a pre-emptive notification of a permanent change
  • temporary notice (T) - information valid only for a limited time.
