Bro
Has your file ever left Sydney office so far? Or your file was actually transferred to Sydney by another VO? My case is processed in Sydney from the very beginning until now (SS). It has never been transferred to any other VO. Not only my R10 was done there, my eligibility was also marked as "passed" by Sydney CIO according to my notes and call agents.
I have heard that in some cases our files will be transferred to CPC Ottava for final review and PPR is sent by Ottava, but I have also seen a small number of people getting their PPR directly from Sydney CIO
