===National Criminal Investigation DNA Database===
The National Criminal Investigation DNA Database (NCIDD) provides Australian police with the ability to match DNA profiles across state and territory borders.

The NCIDD contains DNA profiles from samples collected by Australian police. These profiles are derived from samples collected at crime scenes, or from convicted offenders, suspects, items belonging to missing persons and unknown deceased persons.

The NCIDD enables police agencies to compare DNA profiles from a crime scene with convicted offenders throughout Australia. Additionally, the database allows police to match profiles from two or more unsolved crime scenes, linking seemingly unrelated police investigations.

By 30 June 2012, the NCIDD had linked 69,606 individuals to crime scenes, and had made 12,216 crime scene to crime scene links. At 31 December 2012, there were 713,200 profiles recorded on the NCIDD.

As well as their ongoing day to day value to Australian police, the international value of these systems was proven following the [[2002 Bali bombing|Bali bombings in 2002]] and the [[Australia]]n response to the [[2004 Indian Ocean earthquake|Thailand tsunami of 2004]].
