Quite surprisingly, at the very heart of a bustling city of 4 million, one can find many quiet spots, all within a stone's throw of the office (located on the northern end of the city, just before the Harbour Bridge). In case you're ever in Sydney and need some where quiet, here's a couple of my favourite...
1) Under the Aon Building there are some shops selling great coffee and a really peaceful space overlooking Hickson Street Wharf.
2) Courtyard of St Patrick's. BTW this little church has a fantastic collection of statues located round the internal wall of the building.
~3) Park at Lang Street
~4) Wynyard Park and statue of Reverend J.D. Lang, the minister who founded the Scot's Church.
