that goes some way to explaining too why I was struggling to get shipping data. bugger.
in a perfect world the governing body of Koolan Port would maintain a schedule... as does Townsville, as does Darwon etc for ports under their wathc. but alas, I couldn't find it
here 
I'm not sure where
this or
this site get their data but it does look a lot like marinetraffic, so maybe it too has a short life.
This data I believer adds a huge amount of transparency to otherwise very aloof operators ... shareholders of both GRR and MGX have been well served by this data source. I wonder if the companies would sponsor a page. I suspect they'll hide behind security risk but in reality that can be breached by an anonymous subscription.
have a great day
