From AADSAS's instructions:
"Log into your AADSAS application to check the status of your FRP application, determine if your request has been approved or denied, or if you are required to submit additional supporting documentation to complete your application.
...
You will receive an email notification instructing you that a decision has been made and to check the decision in your online AADSAS application. This is the only time you will receive an email notification regarding your FRP application. It will be the responsibility of the applicant to check the status of their application for additional information and possible deadline dates.
The standard processing time for an FRP application is 4 6 weeks. However, this time can be extended if supporting documentation is required after the initial review of the application."
