What is cultural colonialism in its relation to the Australian Aborigines?

You are using some words that nobody knows the meanings of.

Culture: When two or more people live in the same area they have to adopt some rules about who does what to whom. Any such rule is called a more', pronounced "mor-ay". The adjective form is moral, and the habit of following more's is morality. More's do not have to be right, only accepted. Another group on the other side of the river might have very different more's. A collection of more's defines a culture. The word comes from an ancient word for a plow. Related words are cult, cultivate, colon, and colony.

Colonialism: When a country sends people to create an outpost in a foreign land, that is called a colony. The American colonies were built in mostly uninhabited land because the tribes had been wiped out by an epidemic just before the pilgrims arrived. So "colonialism" in America refers to loneliness and hard work, In other lands, the colonists put the natives to work and grew wealthy as a result, so "colonialism" has a very different meaning, perhaps different in each country.

I have no information about Australian Aborigines.
