Magnetic Island (called Yunbenun by the Wulguru people) is an island located about 8 kilometers (5 miles) off the coast of Townsville, Queensland, Australia. This mountainous island covers 52 square kilometers (20 square miles) and is considered a suburb of Townsville.
You can reach the island by ferry from Townsville Breakwater to Nelly Bay Harbour. A large part of the island, about 39.5 square kilometers (15.2 square miles), is a National Park and a special place for birds. There are many walking tracks that connect the different bays and lead to popular spots like the World War II forts.
Magnetic Island is a popular holiday spot with many hotels and resorts. The local government, Townsville City Council, manages the island's public services. The island is part of the electoral district of Townsville for the Queensland Parliament and the Federal seat of Herbert.
The island has five main towns: Arcadia, Horseshoe Bay, Nelly Bay, Picnic Bay, and West Point. Important natural spots include Rocky Bay, Picnic Bay, Hawkings Point, Nelly Bay, Geoffrey Bay, Bremner Point, Horseshoe Bay, and Cockle Bay Reef.
In 2021, about 2,475 people lived on Magnetic Island.

What's in a Name?
The traditional name for the island is Yunbenun, given by the Wulguru people. The first European to see the island was Captain James Cook in 1770. He named it Magnetical Island because his ship's compass seemed to be affected by a magnetic pull coming from the island. Even today, people have explored the area, but no one has found what caused Cook's compass to act strangely. Locals often call the island "Maggie Isle," "Maggie Island," or "The Island."
Island History
Early Island Life
Yunbenun is the traditional home of the Wulgurukaba people. Long before Europeans arrived, Aboriginal people lived on the island, often moving between seasonal camps in different bays. They used canoes to travel between the island and the mainland. There are stories of ancient burial sites and you can still find Aboriginal middens (old shell heaps) and cave drawings in some bays. Local Wulguru stories tell of a long connection to the island and yearly trips to the mainland to avoid visitors from Papua New Guinea and the Torres Strait who traveled south using the northern trade winds. These visits became less common after missionaries arrived in the Torres Straits in 1871.
European Arrival and Growth
As the nearby town of Townsville grew in the mid-1800s, Magnetic Island became important for its hoop pine timber and granite. The granite was used to build the Port of Townsville and the Customs House.
Picnic Bay got its name because it was a popular picnic spot for European visitors from the mainland in the 1800s. The island also became a place to collect stone and coral for building on the mainland. Some gold was even mined there in 1886.
In 1875, the island was chosen as a quarantine station, a place where people arriving by ship could stay to prevent the spread of diseases. It took ten more years to build the proper facilities at West Point.
In 1896, Cyclone Sigma hit the island and Townsville, causing a lot of damage and sadly, many deaths. The ship Lalla Rookh was found on Magnetic Island after the storm.
By 1890, a resort had opened in Picnic Bay. In 1898, Robert Hayles Sr saw the island's potential for tourism. He started a regular ferry service to the island in 1901 with his ship, the Bee. Even after the Bee was wrecked, his sons built a new ship, the Phoenix. The Hayles company continued to provide ferry services to Magnetic Island until 1988.
World War II Role
During World War II, Magnetic Island became a key defense spot. It was close to Townsville, an important military base, and offered great views over Cleveland Bay, where many ships gathered. Because of this, the Magnetic Battery, also known as "The Forts," was built. This was an artillery battery and observation post located in the hills near Florence, Horseshoe, and Arthur Bays. Picnic Bay also became a popular place for soldiers to rest and relax.
After the War
The island slowly grew after World War II. In 1953, Centaur House, a special place for nurses to recover and rest, opened in Geoffrey Bay.
In December 1971, Cyclone Althea directly hit Magnetic Island. The storm caused huge damage, with 90% of the island's houses either damaged or destroyed. However, the island quickly recovered.
In 2012, some parts of the island were given back to the Wulgurukaba Yunbenun Aboriginal Corporation.
Magnetic Island Today
In 2009, during the Q150 celebrations (Queensland's 150th anniversary), Magnetic Island was named one of the Q150 Icons of Queensland. It was recognized for being a wonderful "Natural attraction."
Island Population
In 2021, Magnetic Island had a population of 2,475 people.

Nature and Fun Things to Do

Magnetic Island is a fantastic place for wildlife. About 76% of the island is part of the Magnetic Island National Park. This park covers the steep, hilly center and the rugged north-western side. The highest point on the island is Mount Cook, which is 497 meters (1,631 feet) above sea level. A special project has recorded over 3,500 observations of 1,126 different species on Magnetic Island. The most commonly seen animal is the koala, and the most common marine animal is the Goldstripe butterflyfish.
Magnetic Island is also famous for its great fishing. You can catch fish like mackerel, giant trevally, queenfish, coral trout, blackspot tuskfish, tuna, fingermark, red emperor, and sea perch.
As of 2013, there were over 800 koalas living on the island. This is the most northern place where koalas naturally live.
The parts of the island not in the National Park can be developed, with local approval. In 2018, the island was experiencing a good economic period.
The remains of the ship SS City of Adelaide can be found off Cockle Bay. It's a popular spot for tourists to visit.
