From September to April migratory wader birds from as far away as Siberia and Alaska look at the island as a place of rest during the long journey home. The wooded island habitat supports small mammals such as possums and some reptiles. Between August and November whales make their passage north past the island and are often seen from the beaches. Wild dolphins are regularly seen with some curious enough to come close to shore. The western side of the island is a beach combers delight with starfish glistening on the waters edge beckoning closer inspection.
Permanent residents are concerned about erosion which many believe is a man made problem.
Some residents claim artifical reefs and dredging of the shipping channel are interrupting the natural sand movement of the island and depriving the beaches of the natural tidal sand replenishment. Moreton Island is criss crossed with swamps and fresh water creeks with many of those leading down to the ocean. An expanse of sand dunes in the islands interior known as The Desert is a popular attraction with visitors.
