German authorities said the bottle was one of thousands thrown overboard during a 69-year-long oceanographic experiment to research global ocean currents and discover more efficient shipping routes. The last bottle with a note to be found was in Denmark in 1934. If it was "Ost" (east) then the bottle was tossed overboard around 900kms west of Mandurah in WA.
The boat, called the Paula, was a three-masted sailing ship that left Cardiff in Wales, most likely carrying coal to Makassar, which is now Indonesia.

Experts from the Western Australian Museum later authenticated it as a message from a German ship.
It emerged the bottle was made in the Netherlands in the 19th century.
Only 662 message slips were returned and none of the bottles.
"I could easily make out the day and month, June 12th but the year was harder to decipher." claimed Kym.
The handwriting on the journal, and the message in the bottle, also matched, he added.
The bottle found on Wedge Island was found "mostly exposed without any form of cork or closure, and was about a quarter full of damp sand", and the bottle appeared to have lain "buried or mostly buried", partially filled with damp sand, Dr Anderson added.
