[10] Rev Dr Giustiniani, the Missionary selected by the Society, is highly approved of by the London and Dublin Committee, for his spirit and acquirements; he is a man singularly fitted to conduct the Mission.
Dr Giustiniani has been in the habit of preaching in London in English, German, French and Italian; he knows, also, the Hebrew, Syriac, Greek and Latin languages.
[11] Giustiniani's first church service was held at Guildford on 31 July 1836 that attracted an attendance of about 60 people in spite of "boisterous weather".
[16] This statement resulted in numerous letters to the Perth Gazette, particularly on the part of "A Publican",[a] criticising his "excess of zeal".
[19] This visit coincided with the murder of an Aboriginal person who was taking flour from a barn, by Ned Gallop, at the direction of his employer Arthur Trimmer, which Giustiniani investigated.
Governor Stirling gave Giustiniani a parcel of his own land at Woodbridge, Guildford, upon which to start a mission and school, which he intended to be along Moravian lines.
For example, in October 1837, Giustiniani defended three Aboriginal persons charged with the theft of flour, dough and butter in the district of the Upper Swan.
[17] In the Swan River Guardian and correspondence, Giustiniani began to openly name and accuse important settlers of acts of violence against Aboriginals.
[22] Giustiniani wrote a series of open letters to Lord Glenelg, critical of the treatment by settlers of the Aboriginals, including allegations of the "blood scene at York".
