Ohh cool cool

Nice to know people are in the same boat!
and do you guys have any idea what I should do if I applied for a TFN, but it just hasn't arrived yet?
From the uni:
Note: as TFNs are usually provided within 28 days of application, it is essential that you apply early to ensure you have your TFN on or before the census date. If you are applying for a TFN for the purpose of obtaining a HECS-HELP loan and it is within one month before the relevant census date, you should request the Tax Office to issue you a Certificate of application for a TFN. If you haven't received your TFN within 10 days before the census date, you should provide this certificate to your provider as proof that you have applied, and then quote your TFN once you receive a Tax file number advice from the Tax Office.
So since it hasn't arrived yet, you need to get that "Certificate of application for a TFN" from the tax office and provide it to the university so they know you have applied for one and will soon be receiving it.
