Set just 34 kilometres off the coast of Mackay, Keswick Island — a spectacular 517-hectare property nestled in Queensland's southern Whitsundays — is officially on offer through Colliers International.
The listing includes 117 hectares of land lease and 25 hectares of marine lease, with development approvals already secured for a mixed-use precinct encompassing high-end residences, a marina, and ecotourism stays.
With roughly $30 million already poured into foundational infrastructure — from sealed roads and solar systems to a functional airstrip — the groundwork for a transformational project has been laid.
Queensland’s tourism engine is running hot in the lead-up to the 2032 Olympic Games.
The Whitsundays welcomed nearly 900,000 visitors in 2024, generating $1.7 billion in tourism spend — more than double its 2019 haul.
Keswick Island’s rare zoning mix — covering tourism, residential, aviation and marine — is drawing serious attention from developers keen to anchor themselves to the region’s growth.
The site’s timing aligns with Australia’s THRIVE 2030 strategy, which targets $230 billion in visitor expenditure by decades' end.
From its rugged peaks to white-sand coves and the vibrant coral reefs that surround it, Keswick Island is more than a blueprint — it’s a living canvas for sustainability and luxury.
Expressions of interest close on 12 August, and with natural wonders ranging from migrating whales to dolphin pods, the appeal is elemental.
“It’s an extraordinary opportunity to craft something enduring in one of the world’s most breathtaking settings,” said Sam Abel, Executive, Hotels Australia at Colliers.
