To join a group, you need to receive an invite code and have a personal Sportsbet account. You can then head to the Bet With Mates section and enter the code to join your group. You may receive an invite code by SMS with a link to join, or simply be given the code itself via the group Admin. 

To join a group, you'll need a valid Join Code, and successfully transfer your Buy-In amount from your Sportsbet personal account to the group account. You must be over 18 and an Australian resident to create a Sportsbet account.
