All applications, by default, are sent to CIO, Sydney. CIO office checks for completeness, encash fee, makes a decision on eligibility (PER or NER). When an application has received a positive determination, it will then be sent to the respective visa office mentioned in your application by the applicant. You will not find any thread about timeline with Sydney. If you look at the spreadsheet, the first two events of Fee encashment and PER are give by CIO and later a 2nd AOR is sent by the visa office to the applicant to acknowledge the receipt of the application in their visa office. CIO is then out of the picture.
Looks like you used a representative to file your application and hence not aware of the process.
