Thanks for asking.
I'll give you some of my observations, just from the questions I see here.
That Australia is an island, a continent and a country.
That the continent is not called Oceania. Oceania is a region.
That our weather is not the same all over the country.
That our seasons are the opposite of those in the Northern Hemisphere.
That like the USA we have more than one time zone.
Also that Sydney, even though it's our largest city, is not the capital city of Australia. Our capital city is Canberra.
That Australia and New Zealand are two different and separate countries.
Really it's basic information.
Foreigners can't be expected to know too much about our way of life unless they've been here or ask questions about it but basic world geography should be taught in the schools.
Yes, I also agree with what Ozmaniac has said.
Add on - that it's rare for any ordinary Aussie to own a gun or to have even handled a firearm of any kind.
Also, we don't tip everyone for everything.
Tipping is not a common practice.
