Forty Five is a small Lady Elliot Island mooring off the west side, set as a lone bommie southwest of the Lighthouse Bommies. It is a short-boat-access reef dive with coral gardens, sea fans, and a strong chance of manta rays, turtles, rays, and dense reef fish moving through the structure. On calm clear days it works best as a slow, close-reef scan rather than a fast wide swim.
