“One of the wonderful things about Sydney Open is it gives you the chance to explore and appreciate places that are normally off limits or that you might have been walking past every day and wanted to see inside.

Focus Tours held on Saturday 3rd November offer exclusive access to 20 nominated sites. These tours cover residential, history aged or limited capacity areas and provide an in-depth insight into the architecture and are led in most cases by their architects or owners.

On Sunday, the City Pass enables ticket holders to get up close and personal with 50 of Sydney’s buildings including the Sydney Fire Station, the King Street Courts, the Great Synagogue and the glorious National Mutual building.
