Thanks for your reply.
I filed it online but I send the related documents by mail. And I also received the receipt document both by email and mail.....
If you have a good look at online Immi applications you'll see that they tell you to upload your documents and then not send them by mail as well, this being I have assumed with TRA = temporary residency application and not a Trades Recognition Australia application.
But just as you can choose to be not totally clear in using abbreviations which can be ambiguous, by ignoring the proper procedure if it has been an application at Immi you have:
. created extra work at Immi
[ that's even if they choose to bother ]
. potentially created a situation where you'll not be able to get anything online
. and at the worst you may have jeopardised your application.
Document receipting is a more or less automatic system.
It'll not necessarily mean a lot of documents have been matched up to your online application.
If it is Immi, it might be a good idea if you get on the phone with immigration and/or contact them by email and in apologetic manner explain how for whatever reason, be it ignorance or whatever you have mailed in documents for an online application and you now realise you have done the wrong thing.
And make a plea for help if it is possible.
