Already submitted Visa application on 7th August under 189, 85 points

Hi all,

I have 85 points and I had got my invite in august start. I already applied visa on 7th August and submitted my medicals on 9th September. Any Idea, how much time it will take now for visa grant or the next message from them?

On immi account it shows general timelines which says 9-14months. Is this really take so much on last stage?

If someone has any experience please let me know.

Thanks. Aradhana
