I'm not sure its the right answer. I kept trying "mount Cook" in NZ, which is 3724m. Thats more than a km higher than Australia's. Not sure if I'm missing something, I'm sure thats the highest in Oceania. And also there's a taller mountain in Papua new guinea, which is usually grouped as part of that continent
The tallest mountain is debated between some sources, so I accept both the tallest mountains in Australia and New Guinea. I did add more type-ins, though.
