The Australian Constitution divides the power of government between the legislative (Parliament), executive (for example the Prime Minister and the Cabinet) and judicial powers (judges), to stop one person, or one group, from holding all the power.
Legislative power is the power to make laws. Parliament has the power to make and change the laws in Australia. Parliament is made up of representatives who are elected by the people of Australia.
Executive power is the power to put the laws into practice. The Executive includes the Prime Minister, Australian government ministers and the Governor-General. Ministers are responsible for government departments.
Judges have the power to interpret and apply the law. Courts and judges are independent of parliament and government.
These powers are written into the Australian Constitution.
