Also note Kiwis on a SCV don't pay capital gains tax in Australia, nor do they have to declare foreign income.
I sought tax advice on this as well

You are a temporary resident if:

• you hold a temporary visa granted under the Migration Act 1958
• you are not an Australian resident within the meaning of the Social Security Act 1991
• your spouse (if applicable) is not an Australian resident within the meaning of the Social Security Act 1991.

Its an amazing benefit!
