Egypt dwarfs Oceania: about 1,003,707 km² km² against 8,600,000 km² km². At true size Egypt is about 8.6× larger — the whole of Oceania fits into Egypt roughly 8 times.
The old Mercator map treated both about equally (1.3× vs 1× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Egypt fits 8× into Oceania.
