What are the three things in Australia today that show influence of British ancestry?

1. Language: The official language of Australia is English, which is a legacy of British colonization. Most Australians speak English as their first language, although there are also a number of other languages spoken in the country, including Chinese, Italian, and Greek.

2. Government: The Australian government is based on the Westminster system, which was developed in the United Kingdom. The head of state is the British monarch, who is represented in Australia by a governor-general. The Australian parliament is made up of the Senate and the House of Representatives, which are elected by the Australian people.

3. Legal system: The Australian legal system is based on the common law system, which was developed in England. This means that Australian courts make their decisions based on past legal precedents, rather than on a written code of law.
