The homicide rate in Australia is particularly low. But in terms of overall homicide rate the United States is higher than the vast majority of other developed countries, and indeed most developing countries.
Most of the world sees the United States as a dangerous country.
For example, using the source you've just given, the US homicide rate is over 5 times the homicide rate of the United Kingdom, France and Germany, and over 10 times that of Norway.
Granted, you're more likely to die in a car accident than to be murdered in the US, but that's no reassurance; this is partly because the vehicle accident mortality rate is so high in the US, at over four times the rate in the UK. And your comment about dying in a plane crash is completely wrong: the air travel mortality rate is very close to zero, with under 200 deaths for over 800 annual million air travellers; a rate of less than 0.025 per 100,000 per annum.
