When just one piece of evidence is presented, the possibility of the Portuguese discovering Australia seems highly unlikely. However when all evidence is taken into consideration, the theory seems more plausible. Recently evidence has started to appear all over Australia that supports the claim. That Captain Cook was not the first European explorer to set foot on Australia. Some people have claimed to have found evidence that the Portuguese discovered the east coast of Australia in the 1520s.
Such evidence includes a Portuguese Brass Cannon found in Western Australia, The Mahogany ship, Bitangabee Bay, Dauphin map, De Jodes world Atlas and La Trobes keys.
The Portuguese Brass Cannon that was found on the Western Coast of Australia is not an acceptable piece of evidence. The Portuguese brass cannon was found in 1916 on an island in the North coast of Western Australia with a date (1512) carved on to the barrel.

The major flaw with this piece of evidence is the fact that the ship has been missing in...
