Osbourne shoals is a lovely dive on a good day.  This was not a good day for me.  I was wearing my dry suit and was underweighted at the start of the dive.  It was also my first dive since the Coolidge and it did bring me back to earth on the differences between Sydney and Vanuatu diving.  The vis was a few metres and it was very surgy as well.  I did not venture far from the anchor, fearing I would start to ascend uncontrolled and end up on the surface prematurely.  I did get a few pics though.
