The Moon vs Australia
The Moon is 3,475 km across. Mainland Australia is about 4,000 km from west to east, so the Moon's disc would not quite cover it. The Moon is still far bigger in total: its surface area is nearly five times Australia's.

What measurements does this comparison use?
The reference values used here are 3,474.8 km for The Moon (Diameter, average) and 7,692,024 km² for Australia (Area). The table links to background sources; natural objects and manufactured variants can differ from these reference values.
How should I read the drawing?
Australia spans about 1.1× as much as The Moon across the longest side of each drawing. This is a linear scale comparison, not a comparison of mass or volume. For maps, the table reports area; doubling a map’s width and height multiplies its area by four.
