Like our friends in the northern hemisphere, we also have our world maps with North facing upwards (although I believe there is no real reason why we shouldn't have south upwards and north downwards)

We do however centre our world maps on Australia's longitutal position (which is basically the same as Japan and far east Asia) so that the Atlantic Ocean is at the ends of our maps.

We don't enlarge Australia.

'Upsidedown' maps are sometimes produced as a novelty, perhaps to raise the point I made earlier in a humourous way
