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.

An anonymous call was made to Australia's anti-terrorism hotline 48 hours before the siege, raising concerns about the content of Monis' website. On his website, Monis had pledged allegiance to "the caliph of the Muslims", believed to be referring to Islamic State leader Abu Bakr al-Baghdadi, and denounced moderate Islam. It has been reported that the Australian Security Intelligence Organisation followed up on the call by reviewing the website and Monis' posts on social media but found nothing to indicate that he was likely to commit an act of violence.
