2014 Sydney hostage crisis
After the siege began, a staged exclusion zone was established with thousands of people evacuated from nearby buildings, including from the floors above the café. The Sydney Opera House was evacuated after a suspicious package was found; however, reports were unconfirmed by police. The US Consulate General in Sydney, located in Martin Place, was also evacuated. Some Sydney schools were put in "white level lockout" due to the hostage situation, which meant that no school group was permitted to leave the school grounds.
Central railway station, Sydney
A riot, dubbed the Battle of Central Station, took place in 1916. Soldiers rebelling against camp conditions had raided hotels in Liverpool and travelled to the city by commandeered trains. Upon arrival at Central station, the rioters set about destroying the station facilities, and fire was exchanged between rampaging rioters and military police. One rioter was shot dead and several were injured. The only remaining evidence of the gun battle is a small bullet-hole in the marble by the entrance to platform 1. This incident had a direct influence on the introduction of 6 o'clock closing of hotels in 1916, which lasted in New South Wales until 1955.
