Adrossan Jetty is an easy shallow dive which is good for beginners and sometimes picked as an alternative for OW certification dives.
The jetty is rather shallow, roughly 1-2 meters, until the end steps, where it drops off to around 4-5 meters. There is plenty of crabs and other macro sealife, along with nudis and ornate cow fish that like to swim around. Rays are also commonly sighted in the seagrass.
The jetty is quite sandy up until about halfway, where seagrass and some broken structure starts becoming more prevalent. Some pylons at the start are in a cross section which may be an obstacle for newer divers.
