HF Marine Communications in Tasmania

The services provided by Tas Maritime Radio are:

1. 24hour,7day monitoring of the International Distress and safety traffic frequencies of 4125, 6215 and 8291 kHz for distress calls from vessels. It should be noted that in line with International measures 2182 kHz will not be monitored.

2. “SECURITE” (Safety) broadcasts as necessary on 4125, 6215 and 8291 kHz.

3. Once per day broadcast of Marine Safety Information on 2524, 4146 and 6227 kHz at 0903 hrs Local Time.

4. Weather forecasts and position skeds (see below).

Tas Maritime Radio is operated during the nominal hours of 0715 – 1945 hrs daily and by TasPorts (Hobart) from 1945-0715 hrs daily.

Although the station is manned by two separate organisations, vessels should call using the same station name Tas Maritimeat any time, irrespective of who is operating the station.

Calling Tas Maritime Radio when an emergency exists

The entire network of Coast Radio Stations around Australia continuously monitor the distress frequencies 4125, 6215 and 8291 kHz. Since the areas of coverage of coast radio stations overlap, it is possible that a distress or urgency call will be heard by several Coast Radio Stations. Your call would be handled by the closest station with the best radio reception.

The process to broadcast an emergency message is:

  1. Select the most appropriate frequency from 4125, 6215 and 8291 kHz. (As a general rule, lower frequencies are needed when closer to Hobart, and lower frequencies are needed during the night)
  2. Make your emergency call (MAYDAY or PAN PAN) in the recognised manner. In order that the most appropriate Coast Radio Station responds, ensure your vessel position is provided in the call.
  3. Tas Maritime will respond to your distress call and advise Tasmania Police. Tasmania Police will take control of any search and rescue (SAR) effort.
  4. Tas Maritime will relay messages between you and the SAR team.
  5. In cases where you require medical advice, information will be relayed to your vessel from the Tasmanian Ambulance Service by Tas Maritime Radio.
  6. If Tas Maritime does not respond to your distress call, another Coast Radio station will accept the call.
  7. If no station answers your call, repeat the call and if there is still no response, repeat on a higher distress frequency.


Marine Safety Information

Marine Safety Information (MSI) broadcasts contain warnings for mariners sent out by the Rescue Co-ordination Centre (RCC) of Australian Search and Rescue (AusSAR), a division of the Australian Maritime Safety Authority (AMSA), located in Canberra. It includes information such as navigation light outages as well as special operations that effect vessel navigation (eg pipe laying in Bass Strait).

MSI information is listed for the Aus-coast areas (labelled A-H) shown in Figure 1.

Most Tasmanian coastal vessels will operate in Aus-Coast Area D.

Every Coast Radio station will broadcast MSI for both its Aus-Coast area and those adjacent. (MSI broadcasts will occur on 8176 kHz only).

Note: Tas Maritime Broadcast MSIs on 2524, 4146 and 6227 kHz

If urgent Marine Safety Information comes to hand, it will be immediately broadcast as a “SECURITE” (Safety) message announced on the distress frequencies 4125, 6215 and 8291 kHz.

Tas Maritime Weather Forecasts and Position Skeds

Latest weather forecasts are provided at 0745, 1345 and 1733 hrs daily. These forecasts are simultaneously announced on 2182, 4125 and 6215 kHz and then simultaneously transmitted on 2524, 4146 and 6227 kHz.

Position reports are taken after broadcast of the weather forecast.

Coastal Waters Wind warnings are broadcast as they are issued (only between 0715 and 1945 hrs daily) by the Bureau of Meteorology. These warnings are announced on 2182, 4125 and 6215 kHz and transmitted on 2524, 4146 and 6227 kHz.

Weather Information

The Bureau of Meteorology (BOM) broadcast marine radio weather forecasts. The broadcasts (for Eastern Australia, including Tasmania) will come from Charleville in Central Australia. The radio station call sign is “VMC”. The weather broadcasts are fully automated, therefore a ship station cannot call up the BOM on “VMC” and expect a response.

The Bureau of Meteorology weather forecast frequencies for “VMC” are 2201, 4426, 6507, 8176, 12365 and 16546 kHz. The BOM publish times that Tasmanian weather will be scheduled on these frequencies. Further information on weather broadcasts should be obtained from the BOM.

GMDSS /Australian Search and Rescue (AusSAR)

The Global Maritime Distress Safety System is also a valid way for vessels to meet their safety communication obligations. Vessels may therefore utilise satellite systems and digital selective calling systems for safety communications. Specific requirements for these systems should be sought from the Australian Maritime Safety Authority (AMSA).
