It was written by Niki Nie, then a 17-year-old girl from America, who was sailing from Vanuatu to the Marshall Islands when she threw the letter overboard, unsure of where it would end up.

In the letter, Ms Nie said the bottle was thrown on January 8, 2019 as she "crossed from the southern hemisphere to the northern hemisphere".

The bottle floated more than 2,500 kilometres across the Pacific Ocean and landed in Mr Amos's hands almost two years later.
