There are many possible reasons why this may occur, but most of them can be easily fixed.
Have you completed your ID verification?
If you haven't, your account may be temporarily suspended due to ID Requirements. Please click here for more information on how to reopen it.
Are you trying to deposit with a Virgin Money, Suncorp, Bank of Queensland or Citibank Credit Card?
Bah bow. Sorry. Unfortunately, these financial institutions don't allow gaming transactions on their credit card accounts, which is simply outside of our control.
Debit card transactions may still work, but if you're with one of these institutions we recommend you hunt down an alternative payment method.
Note: If it's not any of the above and seems a bit more complicated, please get in touch with our Customer Service team.
