I have checked my status at 'https://www.ecom.immi.gov.au/inquiry/query/query.do?action=eVisa%20', too and it shows "Application being processed further" since 16th Dec 15 but all documents checkelist still shows required etc.
Also Immi account has not been updated yet as it still shows Application received., so m not sure what's going on.
Hope we heard something from CO soon or who knows we may get Grant soon.
And have a Happy New Year to All.
Hope this New year bring happiness in all waiting Applicants life, All the best to everyone.
