For great photo opportunities of the Opera House, take a walk over the Sydney Harbour bridge -signposted from The Rocks/Circular Quay. Then use your Day or Weekly 'My Multi' ticket to travel back over the bridge by train. I was going to do the Harbour Bridge climb, but after walking across the bridge, I decided the view from the footway was almost as good and I saved myself AU$180 into the bargain!
The entrance to the footway is a 10 minute walk west (left) from Circular Quay (don't be tempted to walk towards the bridge at ground level-the entrance is much further back).
