Highest peak of Oceania (Carstensz Pyramid)

What to remember

In the Indonesian province of Central Papua, on the island of New Guinea, Puncak Jaya, also called the Carstensz Pyramid, rises to 4,884 m, or 16,024 ft. If New Guinea is counted as part of the Australian continent, it is that continent's highest mountain.

The case rests on geology: New Guinea shares the Sahul continental shelf with Australia. In the Italian Reinhold Messner's version of the Seven Summits, Puncak Jaya replaces the Mount Kosciuszko chosen by Richard Bass.

Both versions are in use, so the challenge has two answers for this continent.
