Yes unfortunately you are cutting it very fine and you almost certainly won't have an AOR which you need for your bridging visa application (first you go into the pool, then you wait for an ITA but you may need 471 points to get invited, then you submit all of your documents, then you get an AOR letter which for most is automatic, some have to wait). Do you have your qualification from WES or another organisation as this takes the longest - minimum 7 weeks for me? Do you have work? Unfortunately IEC cannot be extended.
Sorry for the bad news, but as others have said, 2 weeks is pretty impossible. You will likely lose your worker status and have to apply to be a visitor, wait for your AOR, and then submit your application for bridging visa but I still think that in the meantime you will only have implied status as a visitor, not a worker as implied status is based on your previous status.
