Deep creek is on the eastern side of Hindmarsh Island and also requires local knowledge for safe access. Due to the extensive shallow water as shown in the picture the approach is made by passing channel marker 93 to starboard and then turning to starboard towards the creek. There is a pole marking the outside of the creek (and some shallow water) and a direct transit between the two markers keeping the entrance marker to port will allow a safe entry into the creek.

 Once inside the entrance the creek splits into two branches both of which are only navigable for a couple of hundred metres. The starboard branch has a number of poles that would enable a whole flotilla to moor up in complete safety.
