Once a bustling underwater attraction, the Middle Island Observatory on Great Keppel Island has fallen into obscurity. But here's where it gets controversial... Was it the lack of maintenance, or the changing tides of tourism that led to its demise? The observatory, a marvel of engineering in the 1980s, was a rare kind of tourist attraction. Built from an old Navy dive chamber, it was the largest in Australia when it opened in 1980. It was the dream of Yeppoon man Jim Nimmo, with the support of his wife Sheena. The structure was filled with 500 tonnes of ballast, made of copper and ilmenite, and designed to prevent corrosion with an electrical current. It was a unique experience, with a souvenir shop on the ocean floor and windows for tourists to watch marine life. But the observatory's story is not without its bittersweet moments. A young man's ashes were laid to rest there, and a wedding was held underwater, adding a poignant touch to its history. However, the observatory's future is uncertain. The state government rescinded the leases from the former Great Keppel Island Resort owners, Tower Holdings, in 2023. A demolition company was awarded a tender to clean up the island, and as part of the works, an assessment was to be undertaken of the observatory. The condition of the underwater observatory is still under assessment, and its fate hangs in the balance. Will it be preserved as a historic landmark, or will it be torn down? The controversy surrounding the observatory's future is sure to spark debate, and we invite you to share your thoughts in the comments.
