Oceania: A Region, Not a Continent—Key Differences

Oceania is distinct from the five other inhabited continents (Africa, Antarctica, Asia, Europe, North America, South America) in fundamental ways:

1. Not a Continent: It's a geographic region of ~10,000+ Pacific islands, including Australia, Zealandia (New Zealand), Melanesia, Micronesia, Polynesia.
2. Smallest Land Area: ~8.5M km² (Australia is ~7.7M km²).
3. Least Populated: ~44M people (<1% world). Australia ~26M; Papua New Guinea ~9M; New Zealand ~5M.
4. Extreme Linguistic Diversity: ~1,200+ languages (many endangered). Major: English, French, Indonesian, Tok Pisin, Hindi.
5. Unique Ecosystems: High endemism (kangaroos, birds of paradise, coral reefs). Climates: tropical to subantarctic.
6. Tourism Magnets: Great Barrier Reef, Uluru, Fiordland, Bora Bora, Moai statues.

Oceania's island geography drives its unique biogeography, cultures, and vulnerabilities (climate change).
