http://www.marinetraffic.com/ais/  This web site monitors beaconing AIS 
ship traffic on 161 & 162 Mhz. Just drag the map to where you want it. 
Then zoom in until you see the ship symbols. Click on the symbol if 
you're keen to see the ships details.

 
http://www.dxinfocentre.com/tropo_aus.html  I would think most hams 
using VHF for what ever reason would know about this site. Especially 
the VHF & UHF SSB die hards. Notice the intense ducting in the North 
West. This can be verified against the number of ships being received 
well over the horizon by the one lone AIS receiving station here in the 
Pilbara.
