The reef is located at 360 40’ 51.1” S, 1740 45’ 19.6” E in 6.2 m at minimum spring low tides. This also comprises twelve units with four of the smaller Bay Ball units planted as the central core. There are four Bay Balls around the perimeter; a Pallet Ball at the Eastern point of the octagon; and one further Pallet Ball on the Southern margin. There are slate plates attached to a vertical surface of both these Pallet Balls. Another Pallet Ball is placed on the western side. The last Pallet Ball forms a tail to the south since inclement weather prevented it being placed in geometrical perfection. All the spacings are again about 1.0 metre.
