Hydaelyn at large (is there a compilation of info yet?)

[Enkidoh]

From what I understand, Meracydia is the Australia-equivalent in Hydaelyn - it's an island continent in the south that is regarded as a mysterious 'great south land' (although it should be noted that the ACN class apparently originates from there, meaning the inhabitants are not 'primitive' by any stretch, given ACN uses geometry and esoteric mathematics to generate their spells.

In some respects, FFXIV is following FFXI's lead which also used Earth's continents as a loose basis for it's geography (FFXI's world of Vana'diel featured a Europe/UK/Africa-inspired region similar to Eorzea called 'the Middle Lands' where the original game started and was based aroud, with a barely inhabited continent to the West that was regarded somewhat like North and South America immediately after European contact, a mysterious Australia-like continent to the south, a continent to the East that featured a Persian-inspired 'near East' and an Japan-inspired 'Far East', and a frozen continent to the north that was heavily Norse inspired (specifically, it's filled with barbaric races of giants and Toliken-inspired orcs).

So far, all the information about Hydaelyn seems to strongly suggest that it's geography is set out in a similar manner.
