The Australian government is a federal parliamentary system with a constitutional monarchy. It is divided into three branches: the executive branch, the legislative branch, and the judicial branch. The executive branch is headed by the Prime Minister, who is the head of government, and the Governor-General, who represents the Queen of Australia. The legislative branch is made up of the Parliament, which consists of the House of Representatives and the Senate. The judicial branch is independent of the other two branches and is responsible for interpreting and applying the laws.
The Australian government's functions include making laws, implementing policies, managing the economy, providing public services, and representing Australia internationally. The government is responsible for areas such as defense, foreign affairs, immigration, education, health, and social welfare.
In contrast, the government of Papua New Guinea (PNG) is a unitary parliamentary democracy with a constitutional monarchy. It is also divided into three branches: the executive branch, the legislative branch, and the judicial branch. The executive branch is headed by the Prime Minister, who is the head of government, and the Governor-General, who represents the Queen of Papua New Guinea. The legislative branch is made up of the National Parliament, which consists of a single chamber. The judicial branch is independent of the other two branches and is responsible for interpreting and applying the laws.
The roles and functions of the PNG government are similar to those of the Australian government, including making laws, implementing policies, managing the economy, providing public services, and representing PNG internationally. However, there are some differences in the structure and operation of the two governments, such as the number of chambers in the parliament and the specific responsibilities of the executive branch.
