Hotel Overview

Tucked behind a storied sandstone facade—once home to Sydney’s Fairfax newspaper empire and the venerable Bank of New South Wales—Paradox Sydney pens a fresh chapter on a timeless page. Vintage grandeur and contemporary luxury collide, crafting a stay that is sophisticated, spirited, and ever so slightly unexpected.
Just moments from the Opera House’s striking silhouette, Circular Quay’s bustling waterfront, and Martin Place’s upscale energy, Paradox Sydney positions you exactly where you want to be—and where you least expect. Slip effortlessly from business talks to boutique explorations, unwind at secret laneway bars, and lose track of time at exclusive culinary treasures.
At Paradox Sydney, luxury is the experiences stitched into every moment, from check-in to check-out. It is the impeccable service that always stays one step ahead, the dining that delights at any hour, and the spaces that adapt to every occasion.
Savour Sydney’s eclectic flavours from the break of dawn to the final starlight, or sip something special in one of our stylish bars. Our event spaces are well equipped—smart, adaptable, and primed to bring your grand plans or fleeting fancies to life. As the day softens, retreat to your room where comfort is instinctive, and every thoughtful touch feels like it was left just for you.
Stay strong in the hotel 24-hour wellness centre, where high-performance equipment keeps you on top of your game no matter the hour. Drift into tranquility at our indoor pool, let the hot tub work its soothing wonders, or step into the steam room and watch your worries evaporate. The expert therapists at Tanya Spa are on hand to smooth out the tension with every treatment.
Paradox Sydney is all about great experiences—with a lighter footprint. From cutting waste to conserving energy, we make it easy for you to enjoy your stay while being kind to the planet. Relax, unwind, and feel good knowing sustainability is part of your journey.
