Freckled Duck

I will be arriving in Melbourne on Nov 16 and plan to spend a couple of weeks birding in Victoria.  I know how valuable local knowledge can be, and one of many species I will be hunting is Freckled Duck.  I noted a couple of sightings from W Victoria on Eremaea, and I will eventually be headed that way.  I plan to spend Nov 18th at Werribee.  Am also searching for Blue-billed Duck.  Any recent sightings appreciated.
