The Tank Stream was the source of fresh water for the first European settlers and now it is about 4 meters under the city and not readily accessible to the general public. So we rocked up at our assigned time at Australia Square( which is a Harry Seidler building, which is actually round!)
I love Australia Square, the building is so modern even after 50 years and it has a very swish restaurant at the top ( called O bar) where you can have a drink or a meal and the whole restaurant revolves 360 degrees, a great way to see the city sitting down! We went there for dinner a couple of years back when Vivid Sydney was on.
Anyway back to underground, we had to get into gear, gumboots, hard hats, hi viz vests and safety harness, attend a safety briefing and watch a video on the history of the tunnel and then we were off!

dressed to go! |
Down a ladder and then we were below the city, It was quite low and we had to be careful not to bang our heads, there was quite a lot of water as there had been a bit of rain yesterday ( so much so that they had to cancel yesterday's tours, too dangerous).
The whole thing was done by convict labour, and you can see the pick marks where they were working at the sandstone. They kept to the original course of the stream which has meant that the sandstone has not weathered too much.
