Where are you in Australia?
I know some good meetings in Melbourne, if that helps.
If you want to know what AA is all about and you don't fancy fronting up to a meeting yet, there is a book they wrote called funnily enough, Alcoholics Anonymous.
There are plenty of Pdf versions available on line.
Read that, it's the basic text book of AA and contains information to help you identify your drinking and outlines the plan on how to recover from alcoholism.
Easy and free
