Marine Safety Information (MSI) is broken up into two main areas, weather and other MSI. The other MSI consists of information such as navigational aid details, obstructions and similar.

Weather

The Bureau of Meteorology is responsible for the broadcasting of weather on HF radio through a contract with TVNZ(A).

There are two sets of frequencies, one covering the East of Australia (VMC) the other the West (VMW), these are continually broadcasting on a four hour cycle which means weather for any one area is broadcast six times in any 24 hour period.

Other ways to access weather information

VHF broadcasts weather is also broadcast over VHF channel 67 by Coast Radio Darwin at 0803 and 1803 each day. This consists of the forecast for Darwin Harbour and surrounding areas plus the Coastal Waters Forecast for Daly River to Cape Don.

Phone for weather - there are various types of weather information that can be gained over the phone including:

  • 1900 955 367 – Coastal forecasts, warnings and observation bulletins.
  • 1300 659 214 – Non cyclone warnings including coastal waters and wind warnings.
  • 1300 659 211 – Tropical cyclone warnings and information.

Other marine safety information (MSI)

All marine safety information, excluding weather, is broken down into eight segments around Australia and given a letter from A through to H. These areas are known as the Auscoast Areas or Navarea X.

Marine safety information is broadcast at 57 minutes past the hour somewhere in Australia, see schedule below, on HF radio 8176 kHz. Each HF station broadcasts the warnings for its adjacent area plus the one either side. A Sat-C system instantly receives them as they are issued.
