First of all, the situation in Australia is far more complex then you are making it out to be:

Second, if the US has crime in major urban centers, then contributes to the overall crime rate. Yes there is less crime in rural areas then large suburban areas, but that is true anywhere, because small towns have fewer people, thus they have less crime overall because there are fewer people to commit crimes and its harder to get away with a crime in a small town where everyone knows each other.
Why does say Canada, have a far lower crime rate then the US does? Canada has stricter gun laws and yet Canada is far safer then the US is.
Its not just guns, its also failed social policies, a gap between rich and poor that is far larger then other Western countries and clearly a insufficient mental health system. But the easy access to guns makes these problems worse, not better. Right wingers often say they don't like the government getting bigger, so would they be willing to put more fund into mental health? That's going to cost money, security guards at schools are not cheap either. So you have to pick, more gun control or more money going to all this other stuff and likely a tax hike to pay for it.
There are so many factors that go into a crime rate that cross comparing countries is ridiculous. If this is the route you wish to go, then explain why the UK, Mexico, South Africa and Brazil have a higher overall violent crime rate when they have extremely strict gun laws? It's more telling to look at trends before and after the passing of legislation, which has been the focus of my argument.
Same goes with the trends I discussed. When handguns were banned from DC, they experienced a ridiculous increase in violent crime and murder rates. That has only declined since the repeal of their ban. Coincidence or not, the areas with the most strict gun control laws within the USA have not had in any way, shape, or form any reduction in crime because of it. Chicago and Washington DC are two of the most dangerous places in the country and make up a significant portion of the overall violent crime rate - until recently it was virtually impossible to own a handgun in both areas. Vermont has allowed anybody legally allowed to own a handgun to carry one without a license. Vermont consistently has a very low crime rate.
Answer this question for me, and I will continue to ask it until I get one. If less than 1% of legal gun owners commit a violent crime with their gun, and less than 0.1% is committed by CCW holders, then what good would limitations on legal gun owners do to the overall violent crime rate when a vast majority of guns used in crimes are smuggled in from other countries? (most recent study indicated that a small percentage of guns used in crimes were stolen from legal gun owners).
Why has the US experienced a significant decline in overall crime rates despite a loosening of gun laws and an increase in gun ownership?
Why should another assault weapons ban be introduced when the last one did nothing to prevent violent crime? (not one academic study claimed that it did, and plenty claimed it did nothing).
Why do countless other countries and areas that enact strict gun control experience an increase in violent crime? (UK, Australia, Brazil, South Africa, Washington DC, Chicago etc.) while the passage of CCW laws in many states resulted in a serious reduction of violent crime?
Why has every mass shooting with the exception 2 resulting in the deaths of 4 people or more in the past 50 years taken place in "gun free zones?" Shouldn't these laws be doing something?
Or is it that criminals don't give a flying **** about laws and do as they please?
Right wingers don't oppose having the government act, it's on how they act. They don't want the government encroaching on aspects that they don't need to encroach on - with issues of mental health and school security, that is a different story.
