I feel your pain. I believe (my opinion only) that the checklist can ONLY be used by a registered migration agent. They submit DRC applications differently to our process online and attach this form: http://www.immi.gov.au/gateways/agents/pdf/ma-checklist-ens-visa.pdf
So if you were to attach that form to your application it probably would only be seen once the case officer is assigned after 5-7months in a queue.
Just my opinion though.
Yes, this is ridiculous. I agree Migration Agents can be great and necessary for many, but some people are now using agents and paying them a fortune just to only submit their application as DRC. [it reminds me of people paying farmers to sign off for their 2nd WHV visa] Though this is legal!
Took 8 months for my Nomination to come through and now waiting about two (so far) for my application (ENS186, non-drc, paramatta).
Expecting April 2013!
