The Gumbainggir people knew this island as Giidany Miirlarl, meaning Place of the Moon. It was joined to Coffs Harbour by the northern breakwater in 1935. The walk to the top (quite steep at the end) provides sweeping vistas. From late August to early April this eco treasure is occupied by some 12,000 pairs of wedge-tailed shearwaters, with their cute offspring visible in December and January.
