Oceania by the numbers

Oceania has 14 countries, a combined population of about 44,083,578 โ€” roughly 0.6% of everyone on Earth โ€” across 8,488,031 square kilometres. That works out at 5.2 people per square kilometre against a world average of 59.4.

  • Countries: 14
  • Total population: ~44,083,578
  • Total area: 8,488,031 kmยฒ
  • Average density: 5.2 people per kmยฒ
  • Most populous: Australia (26,177,413)
  • Largest by area: Australia (7,692,024 kmยฒ)
  • Most densely populated: Nauru (603 per kmยฒ)
  • Least densely populated: Australia (3.4 per kmยฒ)

The biggest and the smallest

By population the five largest are Australia (26,177,413), Papua New Guinea (10,142,619), New Zealand (5,124,100), Fiji (929,766) and Solomon Islands (724,273).

The smallest by population are Tuvalu (11,312), Nauru (12,668) and Palau (18,055) โ€” and those are exactly the ones people forget when trying to name every country on the continent.

By land area the order is different: Australia, Papua New Guinea, New Zealand, Solomon Islands and Fiji lead, while Nauru, Tuvalu and Marshall Islands are the smallest. Population and area rankings rarely agree, and noticing where they diverge is one of the fastest ways to build a real feel for a continent rather than a list of names.

Languages and currencies

The most widely used official languages here are English (14 countries), Fijian (1 country), Hindi (1 country), Gilbertese (1 country) and Marshallese (1 country).

Several countries share a currency: AUD, used by 4 and USD, used by 3. Shared currencies usually mark a monetary union or a long-standing peg, and they are worth knowing because one answer often unlocks several.

Learn Oceania properly

Working one continent at a time beats shuffling the whole world, because your memory for places is spatial and neighbouring countries reinforce each other. For Oceania the three angles worth covering are the map, the flags and the capitals.

Do all three for the same continent before moving on. Each one reinforces the other two, which is far more efficient than learning flags globally, then capitals globally, then the map globally.
