Counterespionage

In 1916, a three-masted windjammer bearing Norwegian colours sailed out of a quiet anchorage in Germany, loaded with cargo and apparently bound for Australia. Her true mission was quite different.

In the wake of the Second World War and the realisation that the Soviet Union had set up extensive espionage networks around the world, Australia responded by establishing its own spy-hunting agency- ASIO. By the 1950s its counterespionage activities were increasingly supplemented by attempts at countersubversion-identifying individuals and organisations suspected of activities that threatened national security. In doing so, it crossed the boundary from being a professional agency that collected, evaluated and transmitted intelligence, to a sometimes politicised but always shadowy presence, monitoring not just communists but also peace activists, scientists, academics, journalists and writers.

The British 1940s wartime counterespionage "Operation Jack King" is explained after MI5 archives are opened for this.
