One Country, Six Systems: Why Australian Courts Aren't Named Equally
Australian courts have different names across states primarily because they were established as separate, independent colonial legal systems long before Australia became a single nation.
When the Australian colonies federated in 1901, they kept their existing court structures and names rather than creating a unified national system. This is why a "lower court" in Sydney is called something different than the one in Melbourne.
1. Colonial History and Independence
Before 1901, each Australian colony (like New South Wales or Victoria) was essentially its own "mini-country" with its own parliament and laws. They modeled their courts on the British system but often chose different titles based on the specific English traditions they wanted to emphasize or the legislation they passed.

3. The Federation Compromise
When the Australian Constitution was written, the founders decided on a "dual" court system. Instead of the Federal government taking over all the state courts, they allowed the states to keep their own systems (State Jurisdiction) while creating a separate path for Federal matters.1
This preserved the "State Identity" of the courts. It also explains why Western Australia has its own Family Court of Western Australia, whereas every other state uses the Federal system for family law—WA simply chose not to hand over that specific power to the Commonwealth.
