Hi MP:
The RRV is not an actual sticker or something to be stamped. You only get the one sticker which is for PR. You also get a RRV condition in that same PR for 5 yrs, so you make any number of exits and entries from AU in that time period. What the meaning of RRV is that when you enter AU you are a returning resident and continue your existing PR.
Your first validation trip validates both your PR and your first 5 yr RRV.
What happens once the inital 5 yrs is up.
1. If you are in AU you continue as a PR
2. If you are outside of AU you must have applied for and gotten a new RRV for your passport (this will be a new sticker).
a. If you spent less than 2 yrs in AU in the last 5 then you can apply for and get a 3 month RRV.
b. If you spend greater than 2 yrs in AU in the last 5 then you can apply for and get a new 5 yr RRV.
Hope that clears things up.

Of course many people just get AU Citizenship after 4 yrs net residence in AU (apply for Citizenship) and therefore never have to care about AU visas ever again (as you are no longer a migrant, but a national of AU).
I have a general question on RRV. Does a fresh PR needs to get RRV stamped when he is returning from first validation trip. My assumption is you can make multiple trips to Aus without RRV within first 5 yrs of PR grant. Is it true?
