I was procrastinating online with Google Earth and stumbled across this island southwest of Pakbara:
If you've got Google Earth, take a look around and see what is the best looking island you can find and post up the coordinates for all to fantasise about.
If you don't have Google Earth you can download it here:
http://earth.google.com/ (you only need the free one -- Google doesn't need your money!)
Here's another one -- I'm on a roll here....
South of Ko Rong in Cambodia:
"South of Ko Rong, Cambodia"
That east-facing beach towards the north looks great!
