Try Barracuda Point its where all the ocean currents merge at the end of the island,it really is the wildest drift diving (8kts+ at 30m)but not many of the operators go there. Ive just started a new job so dont get holidays till next year so I am counting the days but if your ever in Sydney I would be only too happy to show u all the great spots in Botany Bay (weedy sea dragons ,blue gropers that eat out of your hands and the grey nurse sharks up real close)or if you plan a trip to oz let me know and I can hook u up with the best operators.If you go anywhaere u want the best guys to look after u. regards Peter
