In the Rare Books Room of the Monash University Library there is a small German pamphlet containing eight letters written by German settlers from New South Wales to their relatives and friends in Germany. The letters were published with the consent of the authors by the Transportation Agent for Australia in Stuttgart, J. F. Cast, in 1855. (Source) Margin no.20, 1988 p.1
Further information about the fate of the German settlers can be found in Margin no.22, [1990] pp.13-26
