Marine radios provide a means of calling for assistance if a vessel is in distress, monitoring and/or updating rescue operations, and positioning a vessel by radio direction finding.
Marine radios operate on:
- VHF marine radio channels
- MF/HF marine radio frequencies
- 27MHz marine radio channels
Marine Radio Victoria
In Victoria, VHF and HF emergency radio traffic is monitored and recorded by Marine Radio Victoria (MRV) 24 hours a day, 365 days of the year.
MRV covers the Victorian coastline, up to 20 nautical miles from the coast on the VHF emergency channels and out to 200 miles for the HF emergency frequencies.
MRV also provides radio checks and broadcasts weather forecasts and warnings.
TSV recommends that boaters install a VHF radio instead of a 27Mhz radio to take advantage of the benefits of MRV and the superior functionality of VHF radios.

Radio weather services
|27MHz||There are weather services provided on 27MHz by some limited coast stations.|
|VHF Marine Radio Victoria||
Broadcasts Victorian coastal waters forecasts - including Bass Strait (4 zones) as well as Port Phillip, Western Port and Gippsland Lakes - on VHF channel 67 at 06:48 and 18:48 EST|
Broadcasts an initial weather warning on VHF Channel 67 as soon as possible after receipt.
Broadcasts current weather warnings at 00:48, 02:48, 04:48, 06:48, 08:48, 10:48, 12:48, 14:48, 16:48, 18:48, 20:48, 22:48 EST on VHF channel 67 following initial broadcast until notice of cancellation is received by fax from the BOM.
Broadcasts notices of cancellation of weather warning as soon as possible after its receipt and at the next scheduled Victorian coastal weather forecast broadcast. NB: Broadcasts of, and cancellation broadcasts of, weather warnings will be preceded by a SECURITE announcement on VHF channel 16.
The Bureau of Meteorology broadcasts weather forecasts to eastern Australia from Charleville on:
8176 and 12365kHz – all hours
Scheduled broadcast times for Victorian coastal waters are:
0130, 0530, 0930, 1330, 1730 and 2130 EST (add one hour for EDST).
Warnings are broadcast every hour starting 0000 EST.
Use of standard procedures avoids confusion and shortens transmitting time.
Unnecessary chatter can mask a weak call for help and one day that may be your call. Only the recommended phonetic alphabet should be used in bad conditions.
Radio operating procedure
Your two-way radio is your communication lifeline so it is important to remember that you:
- Do not transmit unnecessarily
- Listen before transmitting and avoid interfering with other stations
- Use one of the following calling distress channels:
- 27MHz channel 88
- VHF channel 16
- HF frequencies 4125, 6215 and 8291KHz
- Maintain best contact channel or frequency and be guided by the coast or limited coast station when sending distress messages
- Arrange to switch to a working channel once you have made contact with the person you called for non-distress messages
- Always use your call sign or the name of the vessel for identification – use of given names or surnames is not permitted
- Keep messages brief and clear
- Be familiar with the type and syntax of emergency, urgency and safety messages
- State your position, the nature of the distress, the time afloat, the type of vessel and the number of people involved if making a distress call
- Stop transmitting when requested to do so by a coast station.
Marine radio qualifications
The Australian Waters Qualification is the minimum mandatory qualification you must have to operate a VHF marine radio. Learn about the Australian Waters Qualification on the Australian Communications and Media Authority (ACMA) website.
Further study - VHF and MF/HF
The Office of Maritime Communications at the Australian Maritime College (AMC) is responsible for the management of Marine Radio Operators Certificates in Australia.
Radio channel stickers
If you would like us to send you a VHF marine radio sticker, email your name and full postal address to email@example.com
MSV no longer produces 27MHz marine radio stickers.
An alarm signal is used to attract the attention of operators to the incoming message. It produces a two-toned warbling sound which can be easily distinguished, even in poor reception conditions.
How to call for help
Distress messages prefixed "MAYDAY" repeated three times are used only in grave and imminent danger.
Urgency messages prefixed "PAN PAN" repeated three times are used when you or your vessel are not in grave and imminent danger.
Safety signals prefixed "SECURITE" repeated three times (pronounced SAY-CURE-E-TAY) are used when a station wants to pass important information concerning safety such as navigational warnings or weather warnings.
Distress and urgency communications can be made on the following channels:
|VHF||16 (67 alternative)|
|27MHz||88 (86 alternative)|
|HF (frequency)||4125, 6215 and 8291kHz|
