Civilization Pacific Scenario

I've noticed that pacific civilizations are usually ignored in civilization games. Sure there was a Polynesian add-on in civ5 but it didn't do much justice. On top of that, I don't think there was an in-depth Australian aboriginal civilization. I've been planning a scenario for quite some time, here's the setup:

Civilizations

Aboriginal
Koori (Western Australia)
Noongar (Eastern Australia)

Asia
Indonesia

Melanesia
Papuan (New Guinea)
Fiji (Unplayable)

Polynesia
Maori (New Zealand)
Samoa
Hawaii (Unplayable)
Rapa Nui (Unplayable)

Unique Units
Koori- Crocodile Warrior
Noongar- Boomerang Soldier
Indonesia- Keris Swordsman, Elephant Cavalry
Papuan-
Maori-
Samoa-

I know there are a few Polynesian units but none of them have any Polynesian weapons. They are all necessary units as well (spearman, swordsman). Any suggestions for the Papuan units? Any civilizations that should be added?
