I am not sure why you need to contact them before 3 yrs is up. Is it because you need to be in Oz for at least 2 yrs in the 5 in order to renew? If that is the case, you would probably raise flags with them in terms of your renewal.
Here is a trick I did when I was in Australia ... My British passport had to be renewed, so I got another one - it was roughly 3 yrs or so into my PR. In Sydney (by the Rocks), I went to the State Department I asked if I could renew. They said my PR was still valid under my old Passport, but I said I would feel happier if they stamped my new Passport - they gave me a renewal. Maybe you could quickly scamper over there and have it renewed.
But more to your point ... I guess you will have to weigh up which is more important - Oz PR or USA GC.
Where to go to get official info?

You can drill down to get the USA link. Also, I would urge you to talk with an Aussie attorney.
Hope this help.
