He was appointed to St Patrick’s parish in 1880, beginning a long association there with Peter Le Rennetel and Augustin Ginisty, the trio being dubbed the “French Shamrock”by their doting Irish parishioners. From its inception in Sydney in 1881, Piquet was prominent in the development of the St Vincent de Paul Society, and was its spiritual director for many years. He came to be extraordinarily popular as a confessor, and received constant summonses from dying Catholics who wanted him to help them make their peace with God. A short, intense little man, sporting in later life a well-kept white beard, he was typically seen darting through the streets of Sydney in response to some urgent call. To those who heard him preach, or sought his counsel and encouragement in the confessional, he projected warm humanity, deep sincerity, and a special something which people confidently attributed to familiarity with the ways of God; he was regarded by many Sydney Catholics as a living saint. In 1907 he was suspended and declared excommunicated by the archbishop of Sydney, Cardinal Patrick Moran, for his carelessness in observing Church marriage regulations, and protocols for the administration of other sacraments. Although quickly smoothed over, the incident reflected the unease felt by some Irish clergy at the more liberal pastoral approach adopted by the French Marists, particularly in the confessional. Appointed parish priest in 1912, he soon liquidated the parish debt, and constructed an impressive parish hall (1914-15) and senior boys’ school (1919). He was replaced as parish priest in 1920, partly because of poor health, but mainly because of his tendency to ignore directives from his Marist superiors. He remained on the staff at St Patrick’s as an assistant priest, and after 56 continuous years there, he died at Lewisham Hospital, Sydney, on 10 August, 1936.
