I'm uploading India at present (have done west coast of India, Pakistan), 
and am in process of uploading and checking East Coast of India.

I've noticed that Australia has been completed in the last day or so.

Sometimes people keep that updated as they go, sometimes not.

It made my recent upload of Eastern India look terrible (loads of errors), 
but I've now deleted the low res tracing for the affected area.
