Begin by researching and comparing different online poker rooms that accept players from Australia. Key criteria include a valid international license, positive player reviews, a good selection of games, and support for Australian-friendly deposit methods. Once you've chosen a site, locate the 'Sign Up' or 'Register' button, usually prominently displayed on the homepage.

You'll be asked to provide personal details such as your name, date of birth, address, and email address. It is vital to enter this information accurately, as it will be used to verify your identity later, especially when you request a withdrawal. Choose a secure username and password, and agree to the site's terms and conditions.

With funds in your account, you're ready to find a game. Open the poker client's game lobby. You can usually filter games by type (cash game, tournament, Sit & Go), variant (Hold'em, Omaha), and stake level. For beginners, it's recommended to start at the lowest stakes, often called 'micro-stakes', to learn without significant risk.

Click on a table to take a seat. In cash games, you'll buy chips for the table within the allowed minimum and maximum. In tournaments, you'll register and wait for the scheduled start time. Familiarise yourself with the software controls for betting, checking, and folding. Take advantage of play-money tables first if you want to practice the interface.
