Someone colonizing Australia!

What if England wasn't the only country to fully colonize Australia?

America, 1752
The Americans sail across the Indian Ocean to look fro trade and new spices. They sail west in order to search for countries near India and Asia for colonization and embassies to be set up. Fifteen fleets carrying a wide variety of people, from soldiers and civilians to African slaves to be used for trading and labor. Some of the ships eventually landed in what would be modern day Malaysia and Indonesia.

However, some ships sailed onward after setting up a small garrison with military barracks. They sailed farther south to land in what would be known as Western Australia, they quickly started to unload. The Americans did not fully have contact with the native aboriginal people until after setting up the base of operations. Most thought of the people as not much different from Africans. This cause many aborigines were enslaved much like the Africans were, however this did not last long as both the aboriginal and Africans started a rebellion.

This rebellion caused the exodus of the European-Americans from their garrisons into the heart of Australia. In turn for the rebellion, the slaves introduced the native people the works of European and African derived clothing and culture, as well as advanced weapons and livestock. The exodus however, didn't hurt the other Americans. They simply built more garrisons and eventually established small townships.

Soon ships sailed back to Europe form Australia with news of what lied there and more people reported back to their own country about what they saw. This prompted more and more people to travel across the Indian Ocean to Australia and the southeastern islands. Soon nearly all of America inhabited the center mediation of Northern and Southern Australia. While the Africans and aborigines established a new kingdom in Western Australia.

China, 1804
It was not long until news of this spread to the Chinese, the Emperor of China sought to boost the resources of China and create a stronger nation. One extremely large vessel called the "Yellow Dragon" along with many more smaller ships sailed through the Pacific Ocean south and eventually reaching the continent. They settled in what we call Queensland and established a number of small colonies.

They called this land Huang-tǔdì and quickly established agriculture in the fish eastern region of Australia. The Chinese introduced bamboo and silk to this land as crops and resources. The Chinese also congregated with the natives, however they generally ignored them with a few exceptions being for trade and guidance on how to deal with terrain.

The Chinese eventually diverged into multiple provinces within Huang-tudi and each adapting a special style of clothing to distinguish them from others. The Chinese however conflicted deeply with the American settlers. As a result the "Chinese-Caucasian War" started, a war that started over resources and dominance over much of the land.

The Chinese won the war, but much of the land inhabited by the European-Americans was still left dominated by Europeans. A treaty that segregated land from America and China came into being and the two countries established a pecking order in the New World of Australia. Agriculture was a deep success in China's Australia. The major crops being wheat, corn and gaoliang, however more plants were introduced. Livestock was also introduced, but was not as common. Elephants were traded between America and china as they thought they would be best at heavy-lifting and piloting the arid terrain and rhinoceros were introduced by Chinese to be hunted for sport.

Russia, 1860
Russia also colonized a part of Australia, Tasmania and Victoria. The Russian were much more brutal with the natives and sent them back to Russia to be examined and converted to Russian culture. Russians weren't as interested in Australia as they had already colonized New Zealand and began transporting resources back and forth from Russia, New Zealand and Australia.

An animal that they particularly took an interest and liking to was the Tasmanian devil and Thylacine. The thylacine became some what of a mythological creature with new stories popping up featuring them. Russians allied with America and china, foreign a loose medium from both countries. They however despised the Western Dark-skins. Russia also started to study much of the wildlife of Australia and New Zealand, this caused a high interchange of fauna between landmasses.

Coming Together, early 1900s
Back in their home-countries, most of the Australian settlers where all but forgotten about and even fewer people cared after a while. Eventually the Chinese colonies made a deal with the Western Afro-Aborigines and Americans to converge into one empire. Each former territory would become a state or province to the new country dubbed "Zamasia". Zamasian soon took control and dominated the Russians of Tasmania, Victoria and New Zealand, absorbing them into their country.

Culture
The official language in Zamasia is English, however many words used the English language of Zamasia are derived from Chinese and Aboriginal languages. Zamasia is a democracy, run by a executive, legislative and judicial branch. Representation is not based on representation, but rather each province/state receives one single vote and up to four representatives from each territory having seats in the Upper House. Each elected president goes through a ritual and festival originally derived form ancient Chinese culture.

Building architect is largely split between each state, Huang-tudi is mostly made of Chinese-style buildings and houses, in the North-south state of Franklin, the architect is consistent of European and native American-like architect. In the far southern tip, the architect is primarily Russian and Asian based, while in Western Zamasia, seemly primitive villages dominate the province.

Corporal punishment was banned in Zamasia in the mid-1900s to the dismay of the US and China. The legal age of drinking is 19 years and the legal age for consent for sex is generally from about 13 to 15 years of age. Most parents hold a strong value that children are to respect and obey their parents and that they should enforce strong values on their children.

Christianity and Buddhism are the majority religions, while native aboriginal religion, Judaism, Islamic and atheism are the minority.

Ethnicity
Thirty percent of Zamasia consist of Anglo-Europeans, while another consists of Han-Chinese and the other 28% being Africans and aborigines. Miscegenation in the latest years has largely changed this, with White-Chinese and African-Aborigine mixes being the most common. Only about two percent of the population consists of Arabian people.

Ecological Effect
Many species have been introduced, feral cattle and wild boar were intruded by British soldiers. Cougars and white-tailed deer were brought by Americans, cougars actually serve as a new keystone species as they control the population of boar and cattle. Asian elephants and Indian rhinoceros were introduced by Chinese, these animals quickly adapted to their habitat. Camels were also introduced later as beats of burden and formed their own feral populations competing with horses and red kangaroos.
