On commencement at the centre you will be issued with a statement of fees due. It will state full fees until DEEWR has processed your CCB/CCR and returned the information to the centre. This may take several weeks and full fees need to be paid until the reduction can be made, when the adjustment will automatically be made on your next statement. Statements will continue to be issued fortnightly in advance and payments are due fortnightly.  Payments must be made by ezidebit which is an automatic direct debit system. Any change of financial income will alter your CCB/CCR entitlements. Please advise Centerlink  if this occurs.
