Canberra, Nov 7 (TIWN) The government of South Australia (SA) has announced the largest overhaul of its criminal justice database in 30 years.

Corey Wingard, the state's correctional services minister, on Wednesday announced that the government has made a 15-million-Australian dollar (10.3-million-U.S. dollar) down payment on a new system to better-monitor the movement of criminals. 

The decision was prompted by terror attacks on Australian soil, most notably the 2014 Lindt cafe siege in Sydney during which lone gunman Man Haron Monis held 18 people hostage for 16 hours ending in the deaths of Monis and two civilians.  An inquiry into the incident revealed deficiencies in communication between security agencies.  In a separate incident in 2017, Somalian-born terrorist Yacqub Khayre, who was previously known to police, killed one man and held a woman hostage for hours in Melbourne's southeast suburbs.
