Michael McFadyen's Scuba Diving - Crocodile Head
Most places with descriptive names have a pretty good basis for their naming. You know, Perpendicular Point (it is perpendicular), Pigeon House Mountain (it looks like a pigeon house), Botany Bay (there was heaps of new flora and fauna), Broken Bay (this is what it looks like from sea), The Three Brothers (the mountains look like brothers) etc etc. At Jervis Bay there are some dive sites or locations that have similar names. These include The Whorehouse (it really does resemble one I am told), Drum and Drumsticks (they look exactly like these items), Pyramid Rock (it is like a little pyramid) and The Docks (the rocks look remarkably like a series of wharves).
However, Crocodile Head, located about 1.6 kilometres north of Perpendicular Head does not, as far as I can ascertain, even from above, look like a Crocodile. Despite this, the name sticks and is given to the dive sites in and around this location.
The head consists of a large L-shaped arch that extends from below the surface right up above the surface to a height of perhaps 20 metres. This can be swum right through in extremely calm seas.
It is normal to anchor on the southern side of the head, about 15 to 20 metres off the shore. A dive normally starts by swimming over to the wall and then follow it to the right and around to the north. After swimming past the entrance to the arch you will come across a cave that extends back a fair bit. This is very interesting to explore. You can see luderick and black reef leatherjackets outside the cave. The depth in this area can reach 24 metres or so. From here, return back and you will see the other entrance to the arch. This one can normally be entered, depending on the condition of the seas.
In this shallow area (5 to 7 metres), there can be prolific fishlife, including bream. Have a good look around if the conditions permit.
To the west of the shallow entrance there are a number of small caves (there may be one to the east as well, I cannot remember now). These are home to eastern blue devilfish. On dives here I have seen up to seven devilfish on the one dive.
After seeing the caves, explore back away from the wall as you return back to the anchor. The bottom is made up of boulders that have many nooks and crannies.
An excellent dive, normally with very good visibility and fishlife.
