Look at the 1998 numbers, two years after the gun confiscation: armed robbery up 73%, unarmed robbery up 27%, assault up 20%, and unlawful entry up 8%. Again, read 'em and weep at
http://www.ssaa.org.au, the web site of the Australian counterpart to the NRA. The data are compiled and graphed there using official government crime data. Looking at these graphs, also note that, before and after the confiscation, about 30% or less of these crimes even involve firearms to begin with.
