I have trouble with Australia Coordinates.
In the flat world; The distance between the meridians increases towards the South Pole.So doesn't Australia have to be wider in the flat earth?
For Australia; longitudes range from 113.65 to 153.61. (153-113 = 40 pieces of meridians)
Distance between meridians in Equator is approximately 111 kilometers.If we calculate accordingly; => 40 x 111 =4440 km
But This number must increase further for Flat Earth.Because The distance between the meridians in Australia is greater than Equator.

However If you google it, The distance between the east and west of Australia is 4030 kilometers.In this way, After the equator, The distance between the meridians have to decrease towards the South Pole.

It works in the Northern hemisphere as well. It is an easy test of the globe, equal latitudes will have equal distances as their opposite latitude in the other hemisphere.  This is proposed by Rowbotham as a test of the globe if I recall as well.
