Coastal Radio Network Services

The existing marine safety radio service used by most commercial vessels and some recreational vessels operating in waters off the coast is changing from 1 July 2002. The former Commonwealth-funded and Telstra-operated Coastal Radio Network is set to close 30 June 2002 and will be replaced by a HF and VHF system provided by the Sydney, Newcastle and Port Kembla Port Corporations.

Replacement Services 2005

An integrated network of stations operated around Australia by the States and the Northern Territory will monitor the relevant VHF and HF ‘distress and calling’ frequencies and broadcast navigation warning and marine safety information relevant to their broadcast areas.

HF Radio

For HF radio 24 hour, 7 day week service will be operated from Sydney Ports Corporation that will monitor the 4125, 6215 and 8291 kHz distress and calling frequencies. This HF service will cover NSW coastal waters to at least 200 nautical miles of the shore from a new transceiver site in Sydney (Callsign COAST RADIO SYDNEY). Sydney Ports Corporation will also broadcast relevant navigation warnings and marine safety information (MSI) on 8176 kHz at 1057 and 2357 hours and as such warnings are received from AMSA.

The Bureau of Meteorology will broadcast marine weather information for NSW ‘coastal waters’ and ‘high seas’ from VMC Weather Australia East located at Charleville Qld on the existing working frequencies: 2201, 4426, 6507, 8176, 12365 plus 16546 kHz. These broadcasts will be on a 24 hour, 7 day a week basis. These frequencies have been allocated to the Bureau of Meteorology and their use as general working frequencies is no longer practicable.

The Bureau will publicise the scheduled broadcast times.

VHF Radio

For VHF radio, Sydney, Newcastle and Port Kembla Port Corporations will monitor the VHF distress and emergency channel 16 and local weather and navigation warning broadcasts will be provided on VHF channel 67 at 0733 and 1733 hours EST. Severe weather warnings will be broadcast at hourly intervals upon receipt of such warnings from AMSA and until such time that the severe weather conditions no longer exist. This VHF service will only cover waters within the vicinity of Newcastle to Nowra.

Note: the above frequencies are unchanged from those currently used by Sydney Radio.

A Description of Coastal Radio Network Services

27MHz

27 MHz is the main frequency used by recreational boaters and the volunteer services because of its low cost (approximately $200) and its suitability for use in enclosed waters where the majority of recreational boaters operate. This radio provides a range of 10 -15 nautical miles which is usually limited to line of sight.
27 MHz radios allow ship to ship communication between other users of this frequency and ship to shore communication with the volunteer services. 27MHz radios are capable of transmitting distress alerts, receiving weather forecasts and marine safety information provided that the vessel is operating within the coverage area and times of the volunteer services.

VHF

The VHF radios have a better range and clarity than 27 Mhz radios but are more expensive (approximately $400). The Uniform Shipping Laws (USL) Code states that effective VHF coverage only extends to 20 nautical miles from a shore station but may be as far as 30 nautical miles under some circumstances.

VHF also allows ship to ship communication between vessels using a VHF radio and ship to shore communications with the volunteer services, the three port corporations and the Coastal Radio Network (CRN) until 30 June 2002 and the new service beyond that date. This radio is therefore capable of transmitting distress alerts, receiving weather forecasts and marine safety information.

A certificate from the Australian Communications Authority is still required to use VHF radio on boats in Australia. Marine radio users can either obtain a Marine Radio Operators Certificate of Proficiency (MROCP) or a Marine Radio Operators VHF Certificate of Proficiency (MROVCP) to meet this requirement.

However, VHF radio is now covered by a Class Licence, so marine radio users do not need to obtain (and pay for) a separate radio licence.

HF

HF is used for long distance ship to shore communication at a cost of around $4,000. HF coverage is highly variable and dependant on a number of factors such as atmospheric and weather conditions and the power of the HF radio that is being used. Generally speaking HF coverage is up to 200 Nautical miles but under certain circumstances can be considerably more.

Please note: New HF radio services from the Bureau of Meteorology commence from 1 July 2002 when broadcasts via Telstra Coast Radio Stations (voice) and the Royal Australian Navy (radio fax) cease.
