The Australian colony was a Martian colony there was developed to shelter the people of the former earth country of Australia. It was made up of the series of geodesic domes that were named after former cities in Australia on the planet Earth. Part of this colony also included an outback habitat that re-created the natural habitat and ecosystem that existed in Australia. It included koalas kangaroos and Bushbabies. Australia managed to preserve its complicated ecosystem on Mars. By the 26 century, the colony was renamed new Australia and had a population of 400,000 making one of the most populated colonies on Mars after the colony of new China which had estimated population of 700 million.
