In a scenario where the Polynesians colonized Australia around the same time that New Zealand was colonized historically by the Polynesians (so around 1200-1300), what would a Polynesian Australia look like? How would Polynesians deal with the conditions of Australia (granted, they'd mostly stay in the relatively fertile east coast of the continent) and interact with the Aborigines? What would the society and culture of such a Polynesian Australia look like? Assuming minimal butterflies, how would colonization of a Polynesian Australia proceed?
