Some reasons why New Zealand and Australia are wealthier than Papa New Guinea

NZ and Australia are richer and more wealthy because they live in a whole different community. They have animals that help them by pulling things and sometimes they can be transportation. Also they have way more plants which helps them grow more food and they have tech and buildings because in the olden days they would have british prisoners and so they would stay there and basically live their life there. They also have much smarter wealthier people. That is why they have buildings and tech. There are more non-white people and a long time ago they were much less wealthy people and they learned how to survive with sticks and stuff, so they didn't want to live differently so they didn't bother making buildings and tech. Also Papa New Guinea is in the jungles and there aren't many people there so it would be hard for them to build lots of buildings and make things because for one the people don't know how to make buildings and two they live in a whole different place. This is why Papa New Guinea is much less wealthier than NZ and Australia.
