a. British ancestors.

Most Australians are descended from British people. This is because the original people, the Pacific Islander population, was not very large by the time the Europeans arrived. Moreover, this people were decimated by disease and invasion, and this greatly reduced their numbers. Once Australia was colonised, Great Britain engaged in a massive migration campaign by sending their criminals to the island.
