Cape Byron Marine Park is one of four marine parks in New South Wales, Australia, and is the most recently sanctioned. The Cape Byron Marine Park is located in Northern NSW and extends from the Brunswick River to Lennox Head. The marine park extends out to which dictates the border between state and federal jurisdiction. The marine park covers an area of and includes a variety of marine terrain including beaches, rocky shores, open ocean and the tidal waters of the Brunswick River and its tributaries, the Belongil Creek and Tallow Creek. The Cape Byron Marine Park was declared in 2002 and the zoning plan was implemented in April 2006. Of the 15 distinct marine ecosystems identified within the Tweed-Moreton bioregion, the Cape Byron Marine Park supports 10 of these. The Cape Byron Marine Park caters to both commercial and recreational uses including fishing, swimming, diving, walking, and other beach activities. Ecology Cape Byron Marine Park is situated in Northern New South Wales which experiences a sub-tropical climate. The monthly average sea temperature fluctuates between 27.1 degrees in February and 21.6 degrees in July. The Cape Byron Marine Park is also impacted by the East Australian Current (EAC), which transports warm water currents into temperate zones. The presence of the EAC plays an important role in transporting tropical flora and fauna into Southern Hemisphere temperate zones. The Cape Byron Marine Park is located on the Eastern Overlap Zone where warm waters form the north converge with cooler waters from the south. The local marine habitats include exposed and sheltered sandy beaches, rocky shores, rocky reefs, submerged pinnacles, small rocky islands, coral communities, riverine estuaries, coastal creeks and lakes, and sandy seabed habitats. The major ecosystems in the Cape Byron Marine Park are estuaries, rocky shores and platforms, sub tidal reefs and emergent rocks and islands, sandy beaches, and open oceans. Estuaries are located where freshwater creeks and rivers meet the sea. There are three estuaries in the Cape Byron Marine Park which are of two basic types - mature barrier estuaries (Brunswick River) and saline lagoons and coastal creeks (Belongil Creek and Tallow Creek). Rocky shores and platforms are found at various sites within the Cape Byron Marine Park, including Lennox Head, Broken Head and Cape Byron. The notable rocky shores/platforms are the moat at Lennox head, the intertidal boulder foreshore at Lennox Point, the flat rock around Broken Head.
