Family Islands National Park is an Australian national park comprising a group of continental islands lying a short distance off the coast, about midway between Cairns and Townsville, in Far North Queensland. Most of the area has been designated as part of the national park. The islands were given their collective name and also English names by Captain Cook when he sailed through the area in 1770. They were part of the mainland until roughly 8,000 years ago when the sea level rose.
