Australia is a huge country, It can contain the Whole Europe!
Size of Australia is 7.68M KM2!
Population is 23.1 M, if everyone stand alone the coastal line, no one can not see any people at all.....
I have been only a few places, Sydney, Port Lincoln, Adelaide.... All I can say about Australia is big! Big Road, Big cars, I saw a lot of Holden (Australian). But I have not been to there many years, there may have a lot changes. Wish One day, I could travel to this Big Country once more!
