TasRep Guidelines

Reporting Your Position

You must contact Tas Maritime Radio at least once each day, more frequently if you are out of sight of land, possibly following a regular sked, or at a pre-arranged time. Call as you depart and let us know when you intend filing position reports and try to adhere to those times.

At the end of your journey it is especially important that you close your Transit Log by advising that you have arrived at your destination, or when leaving the coverage area, that you are closing with Tas Maritime Radio and now wish to be handed over to an adjacent coast station. (See coverage areas and adjacent coast stations below.)

SE Australia VHF coverage
VHF Coverage

Tas Maritime Radio's predicted VHF coverage is shown in this diagram along with those of adjacent VHF stations. The TMR areas show that Tas Maritime listens on VHF channel 16 and they also show the sked channels used in those areas.

Tas Maritime monitors channel 16 for emergency calls 24 hours each day, and for general traffic between 0700 and 1900 each day.

Outside these coverage areas you can still contact Tas Maritime Radio (if your vessel has the appropriate equipment) using HF radio, satphone or email (see below).

HF Coverage

HF coverage is always affected by atmospheric conditions however Tas Maritime Radio routinely works vessels in New Zealand and the South Pacific. Adverse conditions can make communication on HF very difficult indeed and you should therefore carefully consider which band is best to use at any given time. By day 2MHz & 4MHz should work well up to 300km, 6MHz up to 750km, 8MHz up to about 2000km. All have greater range at night. If you are having trouble with a particular frequency band, try the next higher one.

Tas Maritime Radio monitors HF calling/distress frequencies: 2524, 4125, 6215, 8291 kHz between 0700 and 1900 each day.

Note that if you are testing your HF you will have difficulty receiving if your vessel is in a marina. For best results you need to be in open water.


If you have email on board during your voyage (via satellite) you can communicate with Tas Maritime by sending an email to ops@tasmaritime.com.au. It can be easier to provide positions and other details if there's a lot of radio interference. The same goes for satphone - call +61 3 6231 2276. In an emergency situation email should be the last resort due to the time lag in delivery.
