As a permanent resident, you can live and work indefinitely in Australia. However your permanent resident visa allows you to leave and re-enter Australia multiple times during the initial 5 years from grant.

If you wish to leave Australia after the initial 5 year period, you must have Resident Return Visa (RRV) to enable you to return to Australia.

RRV should be obtained before you depart from Australia and if you leave without RRV, you may not be allowed to return to Australia.
