Isn't it Victoria that have the life means life as in never to be released law? Came in last year i think
Introduced in 1991 after the Julian Knight shootings ... judge can set a life sentence without a non-parole period - that is, not eligible for parole.
A fair indication of sentence (for an extreme abduction, rape and murder) might be Christopher Wayne Hudson who got 35 years non-parole 'life sentence' for a fairly sadistic murder in Melbourne's CBD or Barrie Watts (Murder of Sian Kingi - Wikipedia, the free encyclopedia) for the abduction, rape and murder of a 12-yo schoolgirl
You may be thinking of recent changes to impose compulsory life sentences for certain crimes
