In your second paragraph...Not true...you thnk the aboriginals of OZ, are the indegenous people of Australia...they came from somewhere or you think they materialized out of thin air...never the less it does not discount the fact that theay are the indegenous people of the OZ...
Greeks were the first to inhabit many of the areas of Cyprus which until then were uninhabited. Same with a few others, like the Phoenicians. If we had "Phoenician Cypriots" today they would also be native.
Since then those people, and those those that came after, either just to settle or as populations transferred here by a ruler, were all eventually assimilated into Cypriots.
The TCs were not allowed to be assimilated, although the process had already started when they suddenly told them that they are special and if they fight against the rest of Cypriots several privileges will be granted to them as a reward.
