The territory was originally planned to incorporate the entire landmass of Australia, however Kalmar explorers mapped and claimed the eastern coast while Luxembourg was still gathering a full exploration team together. The ensuing stand-off between the two camps allowed both Aragon and Byzantium to make claims and back them up by force. The Australia Treaty of 1868 divided the continent and avoided a general war.
Most of the kingdom's population is concentrated in or around the two main cities of Sophiastad (on the West coast) and New Aarschot near the Danish Australia border. Sophiastad is often regarded as the most isolated city in the world.
The region is well endowed with minerals, indeed the discovery of gold in 1924 would provide much of the impetus for settlement, and the extraction of them powers most of the local economy. Expanding water pipelines to reach the isolated mining towns is a major concern of the local government but promises even further economic benefits. New Brabanters have garnered a reputation as rough and ready no-nonsense types who regard the rest of the empire as full of useless granaatappels but this has, in the eyes of higher government in Antwerp, made them 'boastful, selfish and combative'. This can be seen most clearly in the ongoing struggle to achieve full citizenship and voting rights for the native Australian people in New Brabant.
