I am also wondering the same thing. I sent in my application to Sydney CIO on March 15th and still no AOR, no nothing! How long does it usually take for FSW3 applicants to hear back? and how long does the whole process take?
Congrats on getting your AOR! I am wondering about the reason for the delay. Did you apply as a foreign worker or an international student? Also did you apply with points for arranged employment. I am just trying to find out if one is faster than the other.
