First Fleet
The First Fleet was commanded by Commodore Arthur Phillip, who was given instructions authorising him to make regulations and land grants in the colony. The ships arrived at Botany Bay between 18 and 20 January 1788; HMS "Supply" arrived on 18 January, "Alexander", "Scarborough" and "Friendship" arrived on 19 January, and the remaining ships on 20 January.
Catholic Church in Australia
The permanent presence of Catholicism in Australia however, came with the arrival of the First Fleet of British convict ships at Sydney in 1788. One-tenth of all the convicts who came to Australia on the First Fleet were Catholic, and at least half of them were born in Ireland. A small proportion of British marines were also Catholic.
