Nobby's breakwater or breakwall is a massive low wall built out from the lighthouse at Newcastle Harbour. Its a very striking landmark and popular for walkers. http://www.visitnewcastle.com.au/ Did the flicker pictures work. In two you can see us walking back towards the lighthouse. The books though were left right at the end of the breakwater itself. Two on large boulders and two wedged between posts in the small watchtower.
