Does anyone think that your more restrictive (as compared with the US) gun laws have reduced crime? Did the laws passed in the 1990s (including confiscation) cause any reduction of crime? Or were there demographic factors involved.
Here in the US, homicides by ethnic group are 19.8 per 100,000 for blacks, 6.4 per 100,000 for Hispanics, and only 1.7 per 100,000 for whites. The 1.7 figure is lower than most European countries.
They claim its about the same or a small drop. The background factor is Australia has doubled police per capita(twice as many cops on the street) since the 90's and the incarceration rate has also doubled. Thats not a net positive effect, except for a dictator in a banana republic maybe.
laws brought in for massacres are an argument full of holes anyway. A massacre as bad as it sounds is just 40 people shot up every 20 years or so. Meanwhile there are a steady 600 killed in regular homicides every year in the same time.
All the billions spent in weapons registration and extra police salaries, claiming to save 20-40 folks from a potential massacre when 15.600 still got murdered.
