No it doesn't, however other parts of the legislation insist that in order to be considered as a 'spouse' you need to be living together. If she is in Norway, and you are in Australia for a few years, then DIMA will likely ask some questions.
Visa issues aside - most people find that living apart for a few years is very difficult.
From this publication on the Norwegian Directorate of Immigration website: citizenship.pdf
"A Norwegian national who applies for and is granted nationality in another state automatically loses his-her Norwegian nationality".
You should read form 968i:
It is possible to get a Resident Return visa (RRV) without meeting the "2 years in 5 residence requirement" however it is possible to get an RRV on concessional grounds if you meet the "substantial ties" requirement and the "5 year rule".
Both of these are explained on form 968i. As far as I understand, some DIMIA offices overseas (notably London and Berlin) are fairly lenient in applying the RRV criteria where there is an Australian spouse or dependent child involved, however this could always change.
And the rules for RRVs are not set in stone, they could be changed anytime.
