That would all be natives. Apart from Great China in Asia, no navy fleet or any ship r capable of reaching aus prior to 1300s. Only until 1400s+ would europeans have ships capable of reaching aus.
Also there have always been ppl before 1788, thats not even the first recorded date of australia being discovered.
Way back in 1600 the dutch has already discovered australia.
Age of discovery started around mid 1350s first by Chinese, who did not travel far south enough to discover aus, that died down in just a few decades. The europeans then continued afterwards with real ocean travelling ships first made around then.
Without colonisation, those dna spread would unlikely to happen. So whatever testing, those r either natives or europeans, there will be no others.
