You are right. If they work in batch then next will be March/April batch. However, i have seen in other thread that they have asked RPRF and other ADR to the batch of oct/nov applicant. also they asked for BIL to the January/February applicant.So, Sydney office is issuing COPRs for 2019 applicants with approved status. Even in past, COPRs had been issued batch wise mostly and now they are priortizing applications which are already approved( that makes sense)... Don't you think guys in the next batch of COPR, there will applicants from March/April/May 2019? As few applicants of these months recieved ghost updates, there could be a possibility that they have passed security verification..
