The cache is not located at the posted coordinates, but it is just less than 250 meters away. To find this cache, first you will have to guess where is this mystery door located in Sydney. You may have seen it already, otherwise I will provide a puzzle to locate it easily. Once you get to the door, you will be able to find the cache just 2 meters away to it's left. You will need a tool to open the cache container that you could find under the door (attached with a magnet). At GZ just untight the lid lightly until the screws are loose (no need to pull them out).
**The door has an inscription: Honi soit qui mal y pense an Anglo-Normal maxim that means, "May he be shamed who thinks badly of it". The saying's most famous use is as the motto of the British chivalric Order of the Garter, founded by Edward III in 1348, admission into which is currently ranked as the third most prestigious honour (inferior only to the Victoria Cross and George Cross) in England and the United Kingdom. It is dedicated to the image and arms of Saint George, England's patron saint.** (FYI - That was just some information about the door, and it is not part of the puzzle).
