The Treasury
Heritage grandeur meets COMO's minimalist calm. Think high ceilings, quiet hallways, natural stone and timber — nothing fussy, nothing loud. It's a city hotel that actually feels restorative.
Book Wildflower well ahead — it fills up fast, especially the 8-course dinner format
Why It Matters
It's the only Michelin Key hotel in Western Australia and arguably the finest city hotel in all of Australia. The building itself — a series of restored colonial-era government offices including the old Treasury and General Post Office — is extraordinary. Wildflower restaurant's six-season indigenous tasting menu is genuinely one-of-a-kind. And the COMO Shambhala spa, set inside the building's vaulted 19th-century cellars, is regularly rated the #1 hotel spa in Australia.
COMO The Treasury is a 48-room, five-star luxury hotel occupying the restored 19th-century State Buildings in the heart of Perth's CBD — soaring sandstone arches, stately colonnades, and all. Designed by the late Kerry Hill, every room feels spacious and calm, with handcrafted furnishings, travertine stone tiles, and oversized windows that pull in the Western Australian light. The hotel holds a 2025 Michelin Key, was named Australia's Leading Boutique Hotel at the 2024 World Travel Awards, and ranked #1 City Hotel in Australia by Travel + Leisure in 2023. And here's the thing: the dining program, anchored by the 3-Chef-Hat rooftop restaurant Wildflower, is reason enough to book a stay.
Where You'll Stay
11 room types available
Cabinet Suite
Once the actual Cabinet Room of the State government of Western Australia. The history is tangible — dormer windows, wood panel detailing, and a view over Stirling Gardens. This is the most character-laden suite in the building. No two guests have ever actually governed from here, but you'd be forgiven for feeling like it.
1 King Bed · 80 sqm
City Room
The entry-level room here is still a proper room — 45 sqm overlooking either Perth's cityscape or the hotel courtyard. Custom-made beds dressed in Egyptian cotton, large windows, and generous en suite bathrooms. Calm, uncluttered, and very Kerry Hill.
1 King or 2 Twin Beds · 45 sqmCOMO Suite
The flagship suite at 120 sqm, overlooking St Georges Terrace and Stirling Gardens. Separate living room, separate sitting room — proper apartment territory. Can accommodate up to four guests with two extra beds. This is the suite for entertaining or for those who genuinely need room to breathe.
1 King Bed · 120 sqm
Family Suite
Two full bedrooms connected by a foyer — the largest accommodation at 150 sqm, with west-facing windows that stay bright through the afternoon. Historic truss ceiling adds character. Options for up to four guests with additional beds. The most practical layout in the hotel for a family or two-room group.
2 King Beds or 1 King and 2 Twin Beds · 150 sqm
Heritage Balcony Room
East-facing rooms with French doors opening to either a Juliet or walk-out balcony above Cathedral Square — one of the better views at the hotel. Two of these rooms have working fireplaces, which are rare and worth requesting in the cooler months.
1 King or 2 Twin Beds · 55 sqmHeritage Room
A step up in size and drama at 55 sqm. Oversized windows flood the room with light and frame views of Cathedral Square, Stirling Gardens, or the city. Generously sized en suites come with a bathtub and separate shower. Some rooms have accessible roll-in en suites.
1 King or 2 Twin Beds · 55 sqmHeritage Suite
Occupying the former Treasurer's office — yes, the actual one — with a historic truss ceiling that makes the space feel genuinely special. Corner position with views toward Perth's Point Zero and Stirling Gardens. Spacious living area and generous bathroom.
1 King Bed · 80 sqmStudio Suite
Located in the Treasury Wing at 80 sqm, these suites are bathed in natural light with views toward Elizabeth Quay and Perth Town Hall. A spacious living area sets it apart from the rooms below. Good light, good views, and the kind of space that makes you want to stay in for a morning.
1 King Bed · 80 sqmTreasury Balcony Room
Corner rooms at 70 sqm with three sets of French doors opening onto north- and east-facing balconies. Expansive sitting areas and generous en suites. The dual-aspect balcony setup is a genuine upgrade.
1 King Bed · 70 sqmTreasury Room
At 75 sqm these are genuinely spacious rooms with generous sitting areas overlooking Cathedral Square, Stirling Gardens, or the city — some with partial Swan River views. The sitting area accommodates an extra bed or cot, making this a solid family option without going full suite.
1 King or 2 Twin Beds · 75 sqmTreasury Suite
Two suites with a residential feel — separate bedroom and sitting room, partial Swan River views, and either a fireplace or truss ceiling depending on the unit. At 80 sqm the layout feels genuinely like an apartment rather than a hotel room.
