The statement that correctly describes a difference between the political systems of Australia and New Zealand is:
In Australia, citizens are required by law to vote in elections; in New Zealand, voting is not required.
This indicates that Australia has compulsory voting laws, whereas New Zealand does not mandate voting, making it voluntary.
The other statements contain inaccuracies:
- Both Australia and New Zealand are constitutional monarchies with parliamentary democracies.
- Australia is a federation with states and territories, while New Zealand is unitary.
- Australia has a written constitution, while New Zealand does not have a single, codified constitution.
