How many people have they had in Australia recently? Australia has less than a quarter of America's population and has never had as many or nearly as many guns or gun owners to begin with. It is not and has never been a valid comparison. It is also incorrect to assume that a weapon ban was the cause of a reduction in crimes committed or wrongful deaths caused. Such theories never look at overall trends in crime in the nation in question. Violent crime was already on the decline in Australia before the ban. Same for the UK. The United States is at an all time low in gun violence and violence in general and both have been trending downwards for decades. You propose that such a ban would reduce violence with no credible evidence while evidence that bans do not work period are glaringly obvious when one looks at the War on Drugs.
