Responsible Service of Alcohol - It's a course you have to undertake before you can serve alcohol.
Here is some info about it in Victoria - I am not sure if your RSA is valid across all states or if it is state by state, it might say in there:

Easy to get, I went to sydneybarschool.com.au, signed up for $40, went to class for a few hours. They mostly tell you not to serve drunk people or underage people. The teachers usually tell you the answers to the test. Nothing to fret about, but necessary for pretty much all hospitality jobs. There's also the RSG for bars that have pokies. over 8 years ago
