Houtman Abrolhos
The Houtman Abrolhos is unusual in having a luxuriant and diverse living coral reef at such a high latitude. 194 species in 50 genera have been recorded there, all but two of which are tropical. This is a surprisingly high coral diversity, considering the high latitude of the reef, and the relatively low diversity of other biota. For a full list, see list of corals of the Houtman Abrolhos.
Muttonbird Island Nature Reserve
Muttonbird Island Nature Reserve is a nature reserve off the shore of Coffs Harbour, New South Wales, Australia, on the southern boundary of the Solitary Islands Marine Park. It is linked to the mainland by a causeway, which acts as the northern breakwater for the harbour. With over 5,500 breeding pairs, it is a major breeding ground for wedge-tailed shearwaters ("Puffinus pacificus"), known locally as muttonbirds, which migrate annually to the Philippines but return to breed on the island.
