## TL;DR

Oceania is a Pacific region often discussed through Australasia, Melanesia, Micronesia, and Polynesia. Its geography combines island arcs, large continental landmasses, oceanic distances, and climate exposure.

## Core Explanation

This repaired entry narrows the public facts to a regional definition, Papua New Guinea's linguistic diversity, and the climate risk facing small islands.

## Detailed Analysis

The previous version bundled many country facts into one source-backed claim and included a generic dispute statement. More detail on Australia, New Zealand, the Ring of Fire, and individual island states should be added with separate sources.
