Adelaide Marriott
Heritage-meets-contemporary. The lobby and public spaces lean into the GPO's history with dark tones and archival photography, while the tower rooms are clean and modern. More polished business hotel than boutique inn, but the art program and building story give it genuine personality.
Marriott Bonvoy Platinum, Titanium, and Ambassador Elite members get complimentary M Club Lounge access — this is worth getting status for, the evening canapé spread is genuinely good.
Why It Matters
Adelaide's first Marriott opened in a landmark 150-year-old General Post Office building, with every piece of artwork in the hotel made by a South Australian artist. The M Club Lounge is frequently cited as one of the better hotel executive lounges in Australia. Several reviewers have noted it punches above its category — closer to a JW Marriott in fit-out.
Adelaide's Victorian-era General Post Office building — built in 1874 — forms the historic base of this hotel, with a sleek modern tower cantilevered above it. The result is 285 rooms with more architectural character than most chain hotels can claim, anchored by a curated art collection spotlighting South Australian artists and First Nations works that reference the GPO's long history in telegraphy, stamps, and meteorology. It's located right on Victoria Square in the heart of the CBD, steps from Rundle Mall and a 15-minute drive from the airport.
