The only thing I'm waiting for is my PCC from Singapore (it's a specific process which I could not have even started before a CO was assigned to me), and I'm starting to panic as it will take longer than the given 28 days to obtain the PCC. I've been emailing my CO to keep her updated of this (no reply, surprise surprise) and also called the main number (DIBP call centre) to check if it's ok to get an extension to the 28 days.
I've read in several forum threads that the extension is usually granted as long as i let my CO know and send her a copy of receipt that i've applied for the PCC, but I wanted to hear it from the horse's mouth as Singapore Police are unable to confirm for me (not 100%) as to whether they will actually send me a receipt once they started processing my application for the police check.
So I called and spoke to a lovely gent who assured me that the 28 days get normally extended provided this is not 4th-5th time i'm asking for the extension. He also said that since i don't have a receipt, it's ok that i just sent other docs to my CO indicating that i've applied for the PCC (such as the receipt that the police station gave me after they had taken my fingerprints).
Hope this helps others in a similar situation & I'll post an update once things get moving along for me, hopefully just a few more weeks
