However, the trial decided that the crimes of two of the mutineers, Wouter Loos (who had assumed leadership of the mutineers after Cornelisz was captured) and a cabin boy named Jan Pelgrom de Bye, were not serious enough to warrant their executions and they were instead marooned in mainland Australia on November 16, 1629 with a small amount of supplies after which they were never seen or heard from again. Their marooning made them the first European permanent residents of Australia; the location where they were marooned is uncertain but the most commonly-accepted point is at the mouth of the Wittecarra Creek near Kalbarri although the area around Port Gregory has also been suggested as a possibility.
