My mother was born in Australia, near Sidney
That's awesome!  That's the largest island continent - its big!  Its the 6th largest country
However, I grew up in Canada and don't know much about Australia.
Until the British settled it, the indigenous Australians spoke more than 250 languages
Really, that's quite impressive that there is so many languages. What is the precentage of indigenous Australians today?
I don't know but the population shrunk from 1.25 million in 1788 to 50k in 1930 - mainly due to diseases like smallpox
