A frogman is someone who is trained in scuba diving or swimming underwater in a tactical capacity that includes military, and in some European countries, police work. Such personnel are also known by the more formal names of combat diver, combatant diver, or combat swimmer. The word frogman first arose in the stage name The Fearless Frogman of Paul Boyton in the 1870s and later was claimed by John Spence, an enlisted member of the U.S. Navy and member of the OSS Maritime Unit, to have been applied to him while he was training in a green waterproof suit.
The Clearance Diving Branch is the specialist diving unit of the Royal Australian Navy (RAN) whose versatile role covers all spheres of military diving, and includes explosive ordnance disposal and maritime counter-terrorism. The Branch has evolved from traditional maritime diving, and explosive ordnance disposal, to include a special operations focus.
Professional diving is underwater diving where the divers are paid for their work. The procedures are often regulated by legislation and codes of practice as it is an inherently hazardous occupation and the diver works as a member of a team. Due to the dangerous nature of some professional diving operations, specialized equipment such as an on-site hyperbaric chamber and diver-to-surface communication system is often required by law, and the mode of diving for some applications may be regulated.
Underwater divers may be employed in any branch of an armed force, including the navy, army, marines, air force and coast guard. Scope of operations includes: search and recovery, search and rescue, hydrographic survey, explosive ordnance disposal, demolition, underwater engineering, salvage, ships husbandry, reconnaissance, infiltration, sabotage, counterifiltration, underwater combat and security.
In-water recompression (IWR) or underwater oxygen treatment is the emergency treatment of decompression sickness (DCS) by returning the diver underwater to help the gas bubbles in the tissues, which are causing the symptoms, to resolve. It is a procedure that exposes the diver to significant risk which should be compared with the risk associated with the available options and balanced against the probable benefits. Some authorities recommend that it is only to be used when the time to travel to the nearest recompression chamber is too long to save the victim's life, others take a more pragmatic approach, and accept that in some circumstances IWR is the best available option. The risks may not be justified for case of mild symptoms likely to resolve spontaneously, or for cases where the diver is likely to be unsafe in the water, but in-water recompression may be justified in cases where severe outcomes are likely if not recompressed, if conducted by a competent and suitably equipped team.
HMAS Canberra was an Adelaide class guided missile frigate of the Royal Australian Navy (RAN). Based on the Oliver Hazard Perry class design, Canberra was one of four Adelaide class ships constructed in the United States of America, and one of six to serve in the RAN.
A clearance diver was originally a specialist naval diver who used explosives underwater to remove obstructions to make harbours and shipping channels safe to navigate, but the term "clearance diver" was later used to include other naval underwater work. Units of clearance divers were first formed during and after World War II to clear ports and harbours in the Mediterranean and Northern Europe of unexploded ordnance and shipwrecks and booby traps laid by the Germans.

Captain Trevor Jackson is an Australian technical diver, shipwreck researcher, author and inventor. In 2002 he staged what became known as the "Centaur Dive", which subsequently led to the gazetted position of the sunken Hospital Ship AHS Centaur being questioned. Jackson is the inventor of the 'Sea Tiger' lost diver location system, and an author on the subject of wreck diving.
The Cave Divers Association of Australia (CDAA) is a cave diving organisation which was formed in September 1973 to represent the interests of recreational scuba divers who dive in water‐filled caves and sinkholes principally in the Lower South East of South Australia (SA) and secondly in other parts of Australia. Its formation occurred after a series of diving fatalities in waterfilled caves and sinkholes in the Mount Gambier region between 1969 and 1973 and in parallel to a South Australian Government inquiry into these deaths. The CDAA's major achievement has been the dramatic reduction of fatalities via the introduction of a site rating scheme and an associated testing system which was brought in during the mid-1970s. While its major area of operation is in the Limestone Coast region of SA, it administers and supports cave diving activity in other parts of Australia including the Nullarbor Plain and Wellington, New South Wales.
Army engineer divers are members of national armies who are trained to undertake reconnaissance, demolition, and salvage tasks underwater. These divers have similar skills and qualifications as professional divers. In the United States Army, they are members of the Corps of Engineers.

In June and July 2018, a junior association football team were rescued from Tham Luang Nang Non, a cave system in Chiang Rai province, northern Thailand. Twelve members of the team aged 11 to 16, and their 25-year-old assistant coach entered the cave on 23 June after a practice session. Shortly after they entered, heavy rainfall began and partially flooded the cave system, blocking their way out and trapping them deep within.
The Kilsby sinkhole is a sinkhole located near Mount Gambier in South Australia. Since the late 1960s, the naturally occurring karst sinkhole has been used for recreational diving as well as civilian and police diver training.
The Women Divers Hall of Fame (WDHOF) is an international honor society. Its purpose is to honor the accomplishments of women divers, and their contributions to various fields of underwater diving. Full membership is restricted to nominees who have been found to meet the WDHOF's criteria, which include being an underwater diver and having contributed to diving in ways recognised as being significant.
