Hoping this issue has been resolved, but this may be helpful in any case:
In Vic and NSW documents (most of the time) auto register and as such they move from lodged to complete almost instantly.
However, there are some instances that they may not; manual examinations or requisitions, for example, will delay registration. In this case, it moves to complete after the registry 'register' the documents (and notify PEXA by sending the completed A9 to the Workspace). The delay depends on the reason why it’s not registered. As such, it is best that you contact the applicable titles office to follow up, as PEXA has no visibility on this aspect.
