Marine Rescue
There are a number of marine rescue services in South Australia, these are all operated by highly trained volunteers who give up their own time and often use their own vessels to assist in the searching and rescue of others.
When not involved in rescue operations they can often be seen on weekends patrolling the coastal waters, and are in constant contact via radio to other boats and also search and rescue base stations.
Marine radio base stations are scattered throughout the state and keep a listening watch on all of the marine radio and citizen band emergency channels. They also provide scheduled calls, and updated weather forecasts and warnings for vessels at sea or on coastal waterways. Many of these base stations have been established in individuals own homes, and are monitored constantly.
On receipt of a distress call, phone calls can quickly be made to the Police and other search organisations. Often other emergency services may be required to assist such as the SA Ambulance Service, State Emergency Service, or the MAC rescue helicopters, large scale searches are normally coordinated by the Marine Rescue Coordination Centre (MRCC) in Canberra and also the local Police.

During larger incidents involving many emergency services a Multi Agency talkgroup may also be allocated to facilitate communications.
