The proportion of Australian voters naming Indonesia as a security threat reached one in five after the Santa Cruz massacre in 1991, subsequently increasing to three in ten following the 1999 crisis in East Timor. In 2004, an Australian Strategic Policy Institute survey showed 29% of those polled identified Indonesia as 'most likely' to pose a security threat to Australia in the future, a slight decline from the figure of 31% recorded in 2001. In all surveyed periods, Indonesia was identified as Australia's foremost security threat.
