I sent a blank email to immigration on Wednesday. They have some system issues with Decision Ready applications. It says
At the moment our system is not readily identifying applications declared as*“Decision Ready”*by a registered migration agent. As an interim measure we suggest that you send an email to the relevant processing office mailbox advising that the application is decision ready with the TRN number highlighted in the subject line. *Please ensure that the application is decision ready.
So contact your MA for this if you lodged a decision ready application.
