2014 Sydney hostage crisis
The 2014 Sydney hostage crisis, also known as the Sydney siege and Lindt Cafe siege, occurred on 15–16 December 2014 when a lone gunman, Man Haron Monis, held hostage ten customers and eight employees of a Lindt chocolate café located at Martin Place in Sydney, Australia. Police treated the event as a terrorist attack at the time, but Monis' motives were subsequently debated. However, the findings of the Coroner in 2017 deemed the event to be a terrorist attack.

On the morning of 9 November, the communications station at Direction Island, in the Cocos (Keeling) Islands group, was captured by the German light cruiser . Before capture, the station was able to transmit an SOS, which was received by the troop convoy, and "Sydney" was ordered to investigate. "Emden"s wireless operators had overheard the distress call and the orders to "Sydney", and prepared to meet the Australian warship.
