Around 7.5km west of Port Campbell, en route to Peterborough, London Bridge has indeed fallen down. It was once a double-arched rock platform linked to the mainland, but in January 1990 the bridge collapsed, leaving two terrified tourists marooned on the world’s newest island – they were eventually rescued by helicopter. It remains a spectacular sight nevertheless. At dusk keep an eye out for penguins, which are often spotted on the beach, generally about 40m away.
