What are the surround countries of Oceania?

Oceania is a vast region that primarily consists of numerous islands scattered across the Pacific Ocean. It does not have surrounding countries in the traditional sense, as it is made up of island nations, territories, and regions. However, it is bordered by larger landmasses like Australia to the west, New Zealand to the southwest, and various island nations in the Pacific such as Papua New Guinea and the Solomon Islands to the north. To the east, it extends towards the Americas, specifically the western coast of North and South America.
