Clois' post is actually some pretty old material, pulled together about a year or so after the great Australian gun ban took effect. The purpose of that data was to impart to Americans generally, and gun-control-advocates specifically, that there is a downside to trying to wipe out private ownership of firearms. Whether it did or not is a matter of ample conjecture. Since that ban has been in place for several years now, it would be good to see some more-current data to see if there actually is a difference beyond subjective good feelings.
Different cultures breed different perspectives on life - too many differences between here and there to make much out of simple data. To each their own. Amazingly enough, there are still many who want to live in The Sudan or in Chad, too.
It's good to see there is some rationale applied to the give-backs, and not just simple emotional bile. It deserves to be mentioned, at least in passing, that those dreaded military style semi autos represent an insignificant proportion of gun crime here in America.
