Sydney Tower
 Sydney Tower is Sydney's tallest building and the third tallest in Australia (with the Q1 building on the Gold Coast and the Eureka Tower in Melbourne being the tallest). However by non-floor height or spire height it is the second tallest in Australia. It is also the second tallest observation tower in the Southern Hemisphere (after Auckland's Sky Tower though Sydney Tower Eye's main observation deck is almost 50 m (164 ft) higher than that of Auckland's Sky Tower).
