The Constitution of Australia provides for three arms of the Federal Government being;

• Legislature – also known as Parliament of Australia, responsible for debating and voting on new laws to be introduced.
• Executive – also known as the Australian Government, responsible for enacting and upholding the laws established by the legislature.
• Judiciary – also known as the High Court of Australia and Federal Courts, is responsible for enforcing Australia’s laws and ensuring that the legislature and executive do not act beyond the powers granted to them by the Constitution or Parliament. 

Some of the central features of the government of Australia are not set down in the Constitution of Australia but are based on custom and convention.

Sections 51 and 52 of the Constitution of Australia describe the law-making powers of the federal parliament.
