Moreton Bay - Geography

Geography

The bay extends some 125 km from Caloundra in the north almost to Surfers Paradise in the south. The bay's southern navigation entrance is the Gold Coast Seaway. The bay is 35 km across at its widest point.

It is separated from the Pacific Ocean by a chain of three sand islands - Moreton Island in the north, North Stradbroke Island, and South Stradbroke Island in the south. Tipplers Passage is the main channel on the western coast of South Stradbroke Island. The Gold Coast Seaway is at the southern extent of Moreton Bay, before the Gold Coast Broadwater.

The bay itself contains around 360 islands in total. This includes the populated Russell, Macleay, Lamb and Karragarra Islands collectively known as the Southern Moreton Bay Islands. Residential development has also occurred on Coochiemudlo Island and Bribie Island. In the past Peel Island has been used as a sisal plantation, quarantine station, asylum and a leper colony.

Moreton Bay is generally shallow and sandy, though a substantive channel is maintained to allow access to the Port of Brisbane at Fisherman Islands at the mouth of the Brisbane River, for international shipping. As well as the Brisbane River, the Pimpama River, Logan River, Albert River, Pine River, Tingalpa Creek and the Schulz Canal all empty into Moreton Bay. Within Moreton Bay are the smaller bays of Waterloo Bay, Redland Bay, Raby Bay, Deception Bay and Bramble Bay.

The bay contains a number of island villages such as the settlement on the bayside of Moreton Island, Tangalooma and on North Stradbroke, Dunwich and Amity Point. Prominent coastal communities and mainland suburbs situated on the bay include Deception Bay, Scarborough, Redcliffe, Margate, Woody Point, Brighton, Sandgate, Cleveland, Raby Bay and Victoria Point and Redland Bay. Other attractions in the bay include Pumicestone Passage and numerous boat ramps, marinas and jetties, including the Shorncliffe pier.

Moreton Bay has at least 102 shipwrecks of which 26 have their exact location known.

Famous quotes containing the word geography:

    Ktaadn, near which we were to pass the next day, is said to mean “Highest Land.” So much geography is there in their names.
    Henry David Thoreau (1817–1862)

    The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.
    Willard Van Orman Quine (b. 1908)

    Yet America is a poem in our eyes; its ample geography dazzles the imagination, and it will not wait long for metres.
    Ralph Waldo Emerson (1803–1882)
