Austronesian comprises 4 main groups:
- Atayalic
- Tsouic
- Paiwanic
- Malayo-Polynesian
The first three are all indigenous to Taiwan and are spoken only on the island of Taiwan. The 4th is spread way the heck all over creation.
Malayo-Polynesian is divided into two main groups:
A. Western M-P
B. Central-Eastern M-P
A. Western Malayo-Polynesian includes the languages of the Philippines, Malaysia, Madagascar, and most of Indonesia. It also includes Cham, which is unusual for being the only M-P language indigenous to the mainland of Asia. Malay is spoken on the mainland too, but it originated in the Riau Islands of Indonesia. It’s broken down like this (just the broad outlines, internally it gets very complex):
- Northern Philippines
- Southern Philippines
- Meso-Philippine (Tagalog goes here)
- South Mindanao
- Celebes
- Borneo (Malagasy goes here)
- Sama-Bajaw
- Sundic (Malay, Indonesian, Javanese, Sundanese, Balinese, Cham all go here)
B. Central-Eastern Malayo-Polynesian has one subgroup called “Oceanic,” for obvious reasons, that includes all the rest of the family. It breaks down like this:
- Central Malayo-Polynesian (Moluccan, Flores, etc. in the Lesser Sunda islands)
- Eastern Malayo-Polynesian:
a) South Halmahera - Northwest New Guinea
b) Oceanic
Since Oceanic includes the Polynesian languages you’re probably looking for, I’ll go into it a couple taxonomic levels deeper. The first 4 or 5 subgroups are in New Guinea.
I. Sarmi-Yotafa
II. Siassi
III. Markham
IV. Milne Bay-Central Province
V. Kimbe
VI. New Britain
VII. New Ireland-Tolai
VIII. Admiralty Islands
IX. Bougainville
X. Choiseul
XI. New Georgia
XII. Santa Isabel
XIII. Santa Cruz
XIV. Southern New Hebrides
XV. New Caledonia
XVI. Loyalty Islands
XVII. Remote Oceanic
The last of these subgroups includes the divisions
a. Micronesian
b. Southeast Solomons
c. Central & Northern New Hebrides
d. Central Pacific
This last one is subdivided further into 1. Rotuman-Fijian and 2. Polynesian. The latter includes more familiar languages like Hawaiian, Maori, Samoan, Tahitian, Tongan.
Why I listed so many obscure little taxons - it shows what a teeny little corner of the family is occupied by the Polynesian languages that are spread over an enormous area. It shows how rapidly the speakers of these languages covered the area, because they are so closely related they dispersed very recently. By contrast, look how 3/4 of the top-level taxons are concentrated in Taiwan. It shows how much older those are, to have stayed in one place for a long time and differentiated deeply. This list also shows that the “Melanesian” languages comprise many different old taxons, while Polynesian and Micronesian are only parts of a single one of those taxons at that level. Really puts things in perspective.

In fact, Ruhlen classified Austronesian not as a family on its own, but as only one sub-branch of a macrofamily called Austric, whose top-level divisions include
I. Miao-Yao (Hmong goes here)
II. Austroasiatic (Munda, Khasi, Khmer, and Vietnamese go here)
III. Austro-Tai - one sub-branch of this is Daic, which includes Thai and Lao, and the other sub-branch is Austronesian. But I will note that Austric, like other long-range macrofamilies, is a controversial phylum.
