In the heart of Perth’s historic Cathedral Square, surrounded by galleries, gardens and some of the city’s best restaurants, COMO The Treasury offers a quietly luxurious base for exploring Western Australia’s capital. Housed within a carefully restored series of 19th-century state buildings, the hotel blends heritage character with COMO’s signature calm — minimalist interiors, a tranquil COMO Shambhala spa, and service that’s polished but never overbearing.
