the English, Europeans & other immigrants (such as my parents) invaded Australia due to the hardships of their lives in Europe & elsewhere
but today, the world has moved on and technological development can sustain humanity very well
imo, no one really "owns" Australia; it is shared
but as alot of land dispossession & psychological dislocation occured to the Aboriginal people (who do share the same traits as Sri Lankan, Malaysian, Indian natives, etc), we have a moral duty to try to get them back on their feet
