How far did Austronesian languages extend from Madagascar to Easter Island before European colonial expansion?

Before the European colonial expansions of the past five centuries, Austronesian languages were more widely distributed than any others, spanning an astonishing 206 degrees of longitude.1

They extended from Madagascar, located just off the southeast coast of Africa, to Easter Island (Rapa Nui), which lies approximately 2,200 miles west of Chile in South America. While the majority of these languages are spoken within 10 degrees of the Equator, their reach extended as far north as 25° N latitude in Taiwan and as far south as 47° S latitude on New Zealand’s South Island.12
