Theft Ranking
Has Weapons-Usable Nuclear Materials


The top-ranked country for the third Index in a row, Australia’s score is unchanged from 2014. In the future, Australia could improve its nuclear materials security conditions by strengthening laws and regulations to require updating of its Design Basis Threat and to mitigate the insider threat. Steps include requiring more stringent and frequent personnel vetting and requiring personnel to report suspicious behavior. Australia’s nuclear materials security conditions remain adversely affected by the presence of groups interested in illicitly acquiring weapons-usable nuclear materials.
