During my permanent residence application, I was given 30days to submit additional documents, and they got back to me by the 15th day thereabout. By the end of the supposed 30days, I had my visa ready.
However, things have changed with AVO, and I honestly don't understand their trend.
The only thing delaying them on getting back to you might be the police clearance, which I presume you will get soon.
It's hard to be still, but you are closer than you think.
You will hear from them soon, we know that they are doing something, but they can be faster and communicate more with applicants, rather than the deafening silence.
