Thanks guys.
The timelines are 8 weeks 6 days. HOWEVER!
I chased this application, and both myself and my MA sent emails of complaint due to it being dragged out. It was hand held through the last few hurdles so not a normal processing at all.
This application should have taken a few weeks at most to be honest. It was a second application and low risk.
Brisbane appear to have a backlog, and they spoke of tighter checks being implemented resulting in a slowdown for all visa classes.
