DEPT HOME AFFAIRS:

From 1 July 2023, New Zealand citizens who have been living in Australia for four years or more will be eligible to apply directly for Australian citizenship. They will no longer need to first apply for and be granted a permanent visa. This means all New Zealand citizens who hold a permanent visa or a Special Category (subclass 444) visa (SCV) are eligible to apply directly for citizenship (by conferral).

These changes only apply to citizenship applications submitted on or after 1 July 2023. If you are a New Zealand citizen, you can check on the day you want to apply to confirm your eligibility.
