Magnetic Island
A landscape as unique as it is beautiful, Magnetic Island is a World Heritage listed National Park within the Great Barrier Reef marine park. Situated only 8km from Townsville, Magnetic Island is the ideal place to relax, unwind and immerse yourself in the romance of a genuine natural paradise. A continental island composed mostly of granite; it was once part of the mainland before the sea level rose about 7500 years ago. The highest point on the island is Mount Cook reaching 497 m (1,631 ft) above sea level.
The name of the island came about because of the apparent “magnetic” effect it had on Captain Cook’s ship compass as he passed the island when sailing up the east coast of Australia in 1770. People have since explored the general area of Magnetic Island with various instruments to discover what might have caused the effect that Cook reported, but nothing has been discovered.
The island’s interesting past has included hoop pine logging, a quarantine station for the port of Townsville, early tourism in the 19th century, pineapple farming and coastal defences during World War II. Magnetic Island’s WWII forts are listed on the Queensland Heritage Register and are among the best examples of such fortifications on Queensland’s east coast.
The Wulgurukaba people, the “canoe people”, lived on the island and nearby mainland for thousands of years. Shell middens, stone tools and art sites are physical reminders of their strong connection with the island.
As you explore Magnetic Island, you’ll come across a number of interpretive signs, designed to tell you about certain relevant aspect of the Island’s ecology and landscape, flora and fauna, cultural heritage, maritime wreck and walking tracks. Visit the Magnetic Island History and Craft Centre in the old Picnic Bay School for more information about the island’s heritage and to view a wonderful collection of old photographs and artefacts.
Natural Heritage and Walks
The island is a haven for wildlife. Two-thirds of Magnetic Island is protected National Park, millions of trees inhabit the island’s landscape, including hoop pines, native kapok and strands of sweet smelling eucalypts that are home to northern Australia’s largest colony of wild koalas. Many other remarkable species of wildlife also inhabit Magnetic Island, such as rock wallabies, the shy echidna, possums and over 100 species of bird life, including the distinctive curlews.
With a network of 25km of walking trails over the island, there is a track to suit all fitness levels. The most popular trail is the Forts Walk. The 2km track leads to a defence based that was built to protect Townsville during WWII. This historical site is comprised of two gun emplacements, an observation tower and a command post that boasts panoramic views over the island and Coral Sea.
Marine Life
More than 150 species of fish inhabit the reefs around Magnetic Island, awarding snorkellers the opportunity for an intimate and exclusive reef encounter. Off the shores of Cockle, Picnic, Nelly, Geoffrey, Arthur and Florence Bays fringing reefs of hard and soft corals support numerous small fish and invertebrates. The waters surrounding Magnetic Island also nourish extensive Sea grass meadows, essential as fish nurseries and providing habitat for the sea turtles and dugongs. During the summer months, sea turtles nest on some of the Island’s beaches. Humpback whales migrate between their Antarctic feeding grounds and the Great Barrier Reef between Aug-Oct, where they mate and breed in the warm waters. Magnetic Island is blessed with front row seats to this inspiring phenomenon.
Scuba and Snorkeling
As a part of the World Heritage listed Great Barrier Reef Marine Park, Magnetic Island has an impressive variety of dive sites and snorkelling opportunities to suit any style. The fringing coral reefs and profuse marine life are easy and comfortable to explore in the warm and moderately shallow waters. The beaches provide a simple entry point for a relaxed offshore snorkel or dive. Boat diving is just as straightforward with the various secluded bays providing ample anchorage points. For the more serious diver, the Island’s waters boast an extensive array of shipwrecks.
A must see experience for the skilled and student diver while on Magnetic Island is a trip to the famous “Yongala” wreck off Cape Bowling Green. Cited as the best wreck dive site in Australia and one of the top five in the world, the site is 90 metres long and lies in approximately 30 metres of water. Visit an important part of Australia’s history while enjoying the incredible range of coral and marine life that inhabit the wreck.
Beaches and Bays
Where the rocky headlands meet the sea, many secluded beaches have formed, some so private, they can only be reached on foot or by boat. These hidden treasures include: the charming Rocky Bay, a very private oasis resting between rugged headlands; Radical Bay, the Island’s pride and a yachties paradise; sparkling Balding Bay, a holiday maker’s haven; Arthur and Florence Bay, abounding in colourful reef life; and the striking, remote Five Beach Bay perfect for the boating and snorkelling enthusiast. Not to be forgotten is the outstanding West Point; this hidden gem is accessible via dirt road and is a popular spot for fishing.
For a more social experience, Magnetic Island’s four residential bays each feature stunning beaches that are all easily accessible and suitable for the whole family. Picnic Bay Beach is the quieter option, with its rustic charm and a jetty perfect for the keen fisherman. Nelly Bay Beach is ideal for a casual afternoon stroll and provides a glorious backdrop for the new Magnetic Harbour.
