Established in 1939 by the Defence Forces to provide landward defence for a country with no naval service, the Coastwatching Service was an unarmed military force numbering approximately 700 and made up of army reservists and men with maritime experience who joined up after the outbreak of war. Manning 83 LOPs, one located every ten miles or so along the coastline, the coastwatchers were the Defence Forces’ primary marine and air intelligence-gathering system during ‘the Emergency’.
