When did you apply?
In my case, the Sydney office only acknowledge receipt of my citizenship application after 3 months since I actually submitted. It takes them a while to go through the pile of new submissions. If you only applied very recently chances are that your papers may not necessarily be lost.
I filed and mailed my application in mid-July 2013. I only got a notice of receipt of my application in mid-October 2013. Prior to that checking the status of application on-line did not reveal any information. Only after an acknowledgment letter has been sent to you will you be able to check the status of your application.
