Want to keep one account over time?
Gone by the end: the worry that a small slip in the form will cost you a withdrawal further down the line.
Locking in the password from the start
Your email address is the identifier for every future login, so the password beside it deserves more thought than the registration form invites. Use a passphrase of several unrelated words rather than a birthday or a name, and keep it out of any browser profile other than your own. If the password slips your mind, a secure reset link goes to that registered address, which is why the email itself must stay under your control. Changing it later means a fresh pass, so get it right at sign-up.
Using the same account on each device
The profile exists once, not once per device. Phones, tablets and the downloadable apps for iOS and Android, alongside the mobile browser, all sign in to the same account with the same email address and password, so your balance, pending picks and bonus progress follow you between them. Signing in on a new device asks for those same details and nothing more. Open the account on the machine you use most, then add the others, and skip the temptation of a second profile created for convenience.
Set limits first, documents early
New profiles settle quickly: the welcome offer is chosen in the cashier as you make the first deposit, which starts from A$6, and no code is typed anywhere. Limits and self-exclusion are open from day one, so set a deposit or loss ceiling before the first bet rather than after a bad night. Identity documents are checked at the latest before your first withdrawal, and that check runs up to 22 hours, so uploading them early saves a wait when a win arrives.
