The Sundays collected its 2026 resort-of-the-year designation from Australian Traveller eleven months before opening day. The AUD 400 million Hamilton Island property—scheduled for December 2025 soft launch—places 120 rooms across beachfront and escarpment sites, with staffed children's programming running parallel to adult-only pool zones and a standalone spa building. Developer InterContinental Hotel Group allocated the capital through its Regent brand relaunch vehicle, targeting the 34 percent of Australian luxury travelers who skip five-star properties because existing resorts offer no credible childcare infrastructure.
The Whitsundays corridor logged 487,000 overnight visitors in the twelve months through June 2024, per Tourism Research Australia. Of those, fewer than 9 percent stayed in properties classified above four-star, even as the region's proximity to the Great Barrier Reef and 74 tropical islands positions it against Maldives and Seychelles itineraries for long-haul Pacific travelers. The Sundays' model separates child and adult experiences without visual or acoustic bleed—dedicated Kids' Club operates 9 a.m. to 9 p.m. daily with marine-biology programming, while the adults-only infinity pool sits 400 meters uphill with no sightlines to family areas. Three restaurants divide by occasion: casual beachfront, fine-dining pavilion, in-villa service. The property employs one staff member per 1.2 guests, matching Aman and One&Only ratios.
The pre-opening award signals a structural shift luxury operators have debated since Rosewood's 2019 guest surveys revealed 41 percent of ultra-high-net-worth respondents traveled with children under twelve but booked family-branded properties—Montage, Ritz-Carlton Reserve's family tiers—over flagship adults-oriented resorts. The Sundays attempts both. Its eighteen villas include four-bedroom configurations with separate children's wings and nanny quarters, priced at AUD 8,500 per night in peak season. That sits 22 percent below comparable Maldives villas but 65 percent above Hamilton Island's existing luxury ceiling. The property also debuts with a fifteen-slip superyacht marina, anticipating the 43-meter-plus vessels that anchor off Whitehaven Beach but lack secure overnight berths. Marina rates will start at AUD 1,200 per night, with fuel, provisioning, and crew-transfer services bundled.
Allocators should watch The Sundays' occupancy trajectory through its first eighteen months—the period when early adopters either validate the family-luxury hybrid or expose it as a hedge that satisfies neither segment. If the property sustains 70 percent-plus occupancy with AUD 2,400 average daily rates, expect IHG to deploy the format across its Regent and Six Senses portfolios, particularly in Fiji, French Polynesia, and the Red Sea projects scheduled for 2027-2028. Competitors are already positioning: Accor announced a AUD 290 million Raffles for the Whitsundays in March 2024, and Rosewood holds conditional development approvals for a 95-key Cairns property. The family-luxury category could absorb AUD 1.5 billion in Australian capital by decade-end if The Sundays proves unit economics.
InterContinental committed the Regent brand to just twelve properties globally when it relaunched the nameplate in 2018. The Sundays is number seven, following openings in Phu Quoc, Santa Monica, and Porto Montenegro. The Hamilton Island bet places 33 percent of the brand's total room inventory in a single corridor that logged near-zero international visitation during the thirty-two months borders stayed closed. That makes December occupancy figures worth the watch.
