If you are a Kiwi in Australia, you hold a temporary visa.  This means you do not get to access many things that would be available to you if you were an Australian permanent resident or citizen.

If you are going to live in Australia for the foreseeable future or know that this is where you are going to live until you are old and grey, you should get Australian citizenship so that you can have all the benefits of a citizen, including access to important welfare payments.  You also will know that your status in Australia is secure.

Doing the admin now will save you a lot of headaches in the future!
