Some familiar sites for Tamsin to enjoy, her home for a year back a few years back.
St Mary's Church in Hyde park. One of the many Ibis hanging around in Sydney. Woolloomooloo Bay Circular Quay, city centre behind. You can "climb" the Harbor bridge for ~$200. or a far less known and advertized tourist venue is the viewing pylon which offers simlar views for $10.
All China towns seem the same ? For some reason Dixon Street food court stuck in my mind from my visit 8 years ago. The power house museum had some interesting exhibits on steam and nuclear power, space and computers. Its a great city to walk around.
