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.
Geography of Sydney
The geography of Sydney is characterised by its coastal location on a basin bordered by the Pacific Ocean to the east, the Blue Mountains to the west, the Hawkesbury River to the north and the Woronora Plateau to the south. Sydney lies on a submergent coastline on the east coast of New South Wales, where the ocean level has risen to flood deep river valleys (rias) carved in the Sydney sandstone. Port Jackson, better known as Sydney Harbour, is one such ria.
