Which bodies are involved in Australia's incomplete separation of powers?

In Australia, the separation of powers is a fundamental principle which divides government authority into three distinct branches: the legislature (Parliament), the executive (government), and the judiciary (courts). The correct choice includes all three bodies, reflecting the understanding that while they are intended to operate independently, some overlap exists, leading to an incomplete separation of powers.

This structure is designed to prevent the concentration of power in one branch and to provide checks and balances among them. For example, the executive is drawn from the legislature — the Prime Minister and cabinet are members of Parliament, which demonstrates the interconnectedness of these bodies. The judiciary, while independent, often interprets laws created by the legislature and ensures that executive actions comply with the law.

Understanding the roles of each branch is crucial to comprehending how Australian democracy functions. The inclusion of only two branches, as suggested in some other choices, disregards the significant role that the legislature plays, while local councils and governors primarily operate at a more local level and do not encapsulate this national framework.
