As long as you have your australian passport, it shouldn't be a worry for you. If you are not a permanent resident, read this: http://www.australia-migration.com/page/Resident_Return_Visa/91 about 6 years ago
If you are an Australian permanent resident (however not a citizen) you'll need to have a copy of a RRV in your passport.
If the visa in your passport has expired, you can get a new one before departing Australia. You can get a new residence visa easily by going to one of the Department of Immigration Offices, it's a fairly straight forward process - all you need is your passport (and your old passport is your expired visa is in that rather than your current passport). I've renewed mine a few times and it's always been fairly hasslefree process.
I'm not sure what the fee for renewal is at the moment, however if you check http://www.immi.gov.au/e_visa/rrv.htm there's heaps of info how to go about this. about 6 years ago
