Help us to help you, log on with VN6KC before departure.


Your radio, whether it be a 27MHz or a VHF, is your link to the mainland while you are at sea. It should be in good working order and tested regularly by conducting radio checks with the volunteer sea rescue group in your area.


By logging your proposed voyage with a sea rescue group, and updating your log when your plans change, you are insuring that someone knows your whereabouts at all times and that a search will be organized should you fail to return on time.

Information required at the time of your logon is as follows:


  • 1. Your call sign and Department Of Transport number, (registration number) commonly referred to as the DOT number.
  • 2. People on board, (inform the radio officer if there are children present), amount of fuel carried and port of departure.
  • 3. Your area of operation (destination or fishing area), be precise, help us to find you!
  • 4. Your estimated time of arrival at your destination or return to your port of departure, referred to as the ETR.


Remember to speak clearly and slowly as the radio officer is recording the information as you speak, try to avoid having an outboard motor running in the background.


A typical radio communication is commenced by calling the required station three (3) times followed by your call sign and the word "over" i.e. "vn6kc, vn6kc, vn6kc, this is Echo Bravo 123, Echo Bravo 123, Over". The use of the phonics alphabet will avoid confusion when using letters during radio communications.


Once the station has acknowledged your call you may commence providing your details for the log. Remember to say "over" when you have completed your transmission. The station will then confirm your log on or will request further information, please be patient, this information is vital for any search and rescue mission that may be mounted later.


Special note: Waterproof stickers are available (free of charge) from our HQ detailing information required and frequencies, both working and emergency, you can also pickup a "Help us to help you" leaflet.

What happens when you logon with your sea rescue group at VN6KC (Rockingham Sea Rescue)


Upon receiving your call sign and / or DOT number the vn6kc duty officer will ask you to commence your logon. Should the officer be busy on another call you will be asked to "Wait One", which means that you are first in line. To avoid over talking another transmission please listen prior to activating your radio.


- Your details will be recorded on a "running sheet" and after confirmation will be transcribed to a "logon slip". This slip is your record and will be updated each time you modify your voyage details.


- All logon slips are slotted in ETR sequence. the top slip being the next vessel due to return to port. Should you not return by your advised ETR the duty officer will commence standard "Overdue" procedures. Yon will be called every 10 minutes for the first 30 minutes before the duty officer informs the Water Police of the overdue incident. The officer will then be guided by the Water Police who will decide when or if we are to commence a search and rescue mission.


- Special note: Please remember to logoff on your return to avoid unnecessary concerns for the duty officer and the Water Police. Once you have logged on you will remain on the log until the duty officer has been advised to remove you.


- Attention all divers! Should you fail to logoff your dive by your advised ETR the duty officer shall call you one time only prior to contacting the Water Police. This procedure is designed to ensure that assistance is made available as soon as possible after your expected ETR
