Kazakhstan dwarfs Oceania: about 2,712,747 km² km² against 8,600,000 km² km². At true size Kazakhstan is about 3.2× larger — the whole of Oceania fits into Kazakhstan roughly 3 times.
The old Mercator map treated both about equally (2.3× vs 1× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Kazakhstan fits 3× into Oceania.
