Blackstone has agreed to acquire Hamilton Island in Queensland, Australia, from the Oatley family. The agreement was announced on 23 December 2025 and remains subject to customary regulatory approvals.

Hamilton Island has been owned by the Oatley family since 2003. The property spans more than 2,800 acres across two islands, with about 70% of the land remaining undeveloped. The island includes five hotels, more than 20 restaurants and bars, retail outlets and an 18-hole golf course on neighbouring Dent Island.

The agreement also includes Hamilton Island Marina, which has 301 berths and can accommodate vessels of up to 60 metres. Its location within the Whitsunday Islands places it close to the Great Barrier Reef and surrounding waterways.

Hamilton Island supports a resident workforce and contributes to economic activity in the Whitsundays through its use of local suppliers and service providers. Marina activity, aviation services, accommodation and hospitality operations together support employment across the region.

Chris Heady, chairman of Asia Pacific and head of real estate Asia at Blackstone, said: “Hamilton Island is an exceptional destination, and we are honoured to build on the vision and dedication that the Oatley family has brought to investing in its transformation and add a standout asset to our portfolio. We are committed to investing in the long-term success of Hamilton Island, its people, and its local businesses and community.”

The Oatley family, Sandy, Ian and Rosalind, said in a joint statement: “We would like to thank our board and management for achieving this outcome, and welcome the new owners, Blackstone. Hamilton Island has a special place in the hearts of many Australians. We are delighted to have a partner of Blackstone’s calibre and resources to continue the legacy, while supporting our people and island community.”

On 6 January 2026, Clayton Utz announced that the firm was advising Blackstone on the acquisition. The Clayton Utz team was led by corporate M&A partners David Wilkie and Rory Moriarty, alongside senior associate Dane McKeen.

A statement issued by Ashurst on 8 January 2026 said the firm was advising the Oatley family on the transaction. The Ashurst team was led by partners Tony Damian and Anton Harris.
