Sydney – Safe Deposit Boxes
Guardian Vaults is Sydney’s premier private safety deposit box facility.
Our flagship Sydney vault is located at Lower Ground, 151 Castlereagh Street, Sydney NSW 2000 — in the heart of the CBD, steps from the Westfield Sydney and accessible via multiple train and bus routes.
We are now also assuming management of Westpac’s former safe custody facility at 341 George Street, Sydney as part of our national agreement with Westpac Banking Corporation — bringing a second Sydney location under the Guardian Vaults umbrella.
Whether you’re a new client looking for secure storage, or an existing Westpac customer looking to continue your lease, Guardian Vaults Sydney offers the most trusted, independently operated vault facilities in the city.
