While in Hamburg, Kavel was informed of the possibility of migrating to Australia. He travelled to London, England, to meet with George Fife Angas, the chairman of the South Australia Company, which was searching for emigrants to settle the land acquisitions it had in South Australia. Kavel was received favourably by Angas, who sent his chief clerk, Charles Flaxman, to Prussia to meet with Kavel's group and to prepare them for emigration. Kavel remained in London, ministering to the German community.
