Pastor Kavel was not initially one of this group. Frederick William’s revised edition of the worship agenda, which was released in 1829, was voluntary for usage in congregations, as was the first edition. Pastor Kavel used this worship order until 1834 when, under the influence of the writings of Johann Gottfried Scheibel, he ceased and joined the ranks of the dissenters. Kavel wrote to the King in January 1835, informing him that he would no longer use the worship agenda. On Easter Monday 1835, Kavel was removed from the ministry and was prohibited from practising as a pastor. His congregation likewise were prohibited from using the church premises, and participating in any worship services presided by suspended Pastors.
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.
The congregation in Klemzig went through a number of setbacks in their application to emigrate. Requiring permission from the government, they were informed that their request for emigration had been denied in 1837. Representatives who were sent to appeal against the denial were arrested and imprisoned. It was only at the end of 1837 that the group was finally given permission to emigrate.
Financially, the migration was expensive. George Angas had lobbied the South Australia Company to provide funding for the Lutheran dissenters, arguing that the character of the people was the ideal type for the new settlement in South Australia. However, due to financial problems within the Company, the request by Angas, which had initially been approved, was now denied. Many of the Prussian migrants had also encountered financial hardship due to the extended emigration application process. A migration to Australia now appeared to be impossible.
George Angas decided to personally provide funding to Kavel and the Klemzig group. Four ships were chartered on their behalf: the Prince George, the Bengalee, the Zebra and the Catharina. The Prince George and the Bengalee left Hamburg on 8 July 1838 with about 250 of the emigrants. They travelled to Plymouth, where they picked up Pastor Kavel, and then continued on their journey until they arrived in Port Adelaide on 20 November 1838. The Zebra left in August 1838 with 187 on board and arrived in Holdfast Bay on 28 December. Eleven people, six adults and five children, died on the trip. The Catharina left in September 1838 and arrived in January 1839. In all, this group of ships transported 596 migrants from Prussia to Australia.Klemzig. On the arrival of the third ship, the Zebra, the town Hahndorf was established. A third settlement of the Prussian migrants was established by many of the passengers of the Catharina at Glen Osmond.
On 23 and 24 May 1839, Kavel convened a meeting of the elders of the three villages. At this meeting, the constitution of the new Australian Lutheran synod was adopted. At the following synodical gathering in 1840, a letter was drafted and subsequently sent to the “Old Lutherans” in Prussia. Its purpose was to encourage others to emigrate and, most importantly, have a second pastor immigrate to Australia. On 28 October 1841, 224 further Prussian immigrants arrived in Adelaide on the Skjold, among them Pastor Gotthard Fritzsche. This group formed the main part of the settlements at Lobethal and Bethanien. In 1842, Langmeil was settled. Kavel remained in South Australia until his death.
