After Pizza reef we dived Osbourne shoals.  Always a favourite this one.  We anchored close to the cave at the N end of the reef but had to drag the anchor across the sand to get it to the reef.  Wind was up so we know the anchor had to be well secured.  We headed south along the all and all the way to the southern end of the reef.  Here my air was at turning point.  We found a giant cuttle under a ledge at this end and it kept us entertained, also following us back for a while.  I did see a devilfish but it disappeared before I could get my camera to bear. 

Viz was not as good as at Pizza but still a good 8-10m.
