Thank you for the post!
After a long wait I gave immi a call this morning and found out my request was approved.
The ceremony letter is on the way being sent out and I am going to a departmental ceremony on 4th Feb, well before the payment due date for next semester, 14th Feb.
Best of luck to you too, I hope you will have a wonderful moment at the ceremony.
ps. After checking with the immigration on the phone, the ceremony letter arrived in the mailbox two hours later !!
