Auriga Investment Group has struck a franchise agreement with Hilton Hotels & Resorts to bring the global brand back to South Australia, with a 251-room Hilton Adelaide East End to open within the Arcadia mixed-use project.
The 27-storey hotel, located at 299 Pirie Street, will be operated by Trilogy Hotels, the independent hotel management company founded in late 2023 by hospitality veterans Scott Boyes, Tony Ryan and Grant Alchin.
The deal marks Hilton's re-entry into the South Australian market after Hilton announced last year that it was exiting its long-standing Victoria Square property after it was acquired by Thai hotel group Amora Hotels and Resorts.
The move also boosts Trilogy's rapidly expanding portfolio, which now totals more than 3,700 rooms across 22 hotels.
"The return of Hilton to Adelaide is both a symbolic and strategic milestone,” says Tushar Raniga, director of development for Hilton Australasia.
“This project allows us to reintroduce Hilton Hotels & Resorts as a modern, design-led flagship aligned with Adelaide’s growth and evolving skyline.
"Auriga’s vision and the site’s exceptional location make this an ideal opportunity to re-establish Hilton’s presence in South Australia in partnership with Trilogy Hotels.”
The Arcadia project received State Commission Assessment Panel approval in February 2025 as a dual-tower development incorporating hotel and residential components.
The Hilton Adelaide East End is expected to be operating in 2031 offering rooms from 31 to 140 square metres, with the property to include 303 square metres of meeting space, a pool, fitness centre and multiple food and beverage venues.
“For more than four decades, Hilton has played a defining role in Adelaide’s hospitality landscape, and Auriga is honoured to be part of its rebirth," says Eric Luk, director at Auriga Investment Group.
"Arcadia was conceived as a place where community, design and city life come together - a precinct that blends a new residential neighbourhood with a flagship Hilton hotel.
"Together, they will create a destination that draws locals back into the CBD and supports the year-round calendar of events that make Adelaide unique.
"This is a long-term investment in the city’s future, and we are committed to delivering a precinct that elevates Adelaide for generations to come.”
The project represents a significant milestone for Trilogy Hotels, which burst onto the scene in March 2024 when it secured management rights to four Schwartz Family Company properties - the Mercure Sydney, Ibis Sydney World Square, Mercure Canberra and Fairmont Resort Blue Mountains.
“Every great city needs a Hilton hotel, and we are honoured to have been appointed by Auriga Investments as operator of the new Hilton Adelaide East End," says Scott Boyes, CEO of Trilogy Hotels.
“This landmark project underscores Trilogy’s dedication to maximising performance for hotel owners while creating memorable stays for our guests.
"By combining Trilogy’s local expertise and disciplined operations, along with Hilton’s powerful loyalty program, the hotel will set a new benchmark for quality and service in Adelaide.”
Since its founding, Trilogy has pursued an aggressive growth strategy, building a pipeline that spans capital cities and regional markets.
Boyes, Ryan and Alchin each bring decades of experience from senior roles across major hotel groups, positioning Trilogy as an independent operator in an Australian market long dominated by global chains.
For Auriga Investment Group, the Hilton branding elevates a development that sits within Adelaide's East End precinct, one of the city's most sought-after hospitality and cultural corridors.
