The+Geelong+Keys

The Geelong Keys were a set of five keys discovered in 1845 or 1846 in the time of Governor Charles La Trobe at Corio Bay in Victoria, Australia. They were embedded in the stone of the beach in such a way as to make him believe that they had been there for 100–150 years. Since the earliest proven English exploration of the area was by Matthew Flinders in 1802, writer Kenneth McIntyre suggested the keys may have originated with some earlier European explorers of the region, possibly Portuguese explorations.
