Given the variable visibility, it's worth checking recent dive reports before heading out, as a 20-metre vis day makes this site considerably more rewarding than a 5-metre one. Always perform a thorough surface check and use a DSMb on ascent given the boat traffic overhead.
Drive south to the Botany Bay National Park and pay the entrance fee. Follow the road to the Yena Gap area on the dirt road. Drive to the parking area and walk down the cliff face to the shoreline.
