Hi Kimmo,
Yes, the email states which team is processing the application. There wasn't much in the initial email. Just a "Please see the attached information". With the email came three word documents. One was titled 'Client Service Information' and was an explanation why they are collecting data from applicants and what they are doing with it. The second one was a letter, which told me that the department has begun considering my application and that they are requesting more information from me within the next 28 days. It also talked about an attached checklist (which wasn't attached) and there was another attachment that described in more detail the information that I am supposed to provide.
There is a link on this website that I have used to upload my documents: http://www.immi.gov.au/e_visa/general-skilled-migration-attachments.htm. The system is very basic. There is a drop-down menu where you can choose which type of document you want to upload (domestic PCC, foreign PCC, Form 80, relationship evidence, passport, etc.), a field where you can write a very short description and an upload button. Once you have uploaded your document it appears in a table alongside the description you wrote. A bummer is that you cannot update or edit it once it is online, so any mistakes you make (typos, wrong document) stay online.
By the way, our medicals were done on Monday and on Wednesday the system already showed them as finalised. That was quick!
