There was a Rev Benjamin Dyer who preached in Tassie during the 1820s. During that time there were others more famous. They were Rev Richard Johnson who came out on the first fleet to N.S.W, William Broughton, Thomas Scott and Samuel Marsden. The first Diocese in Tasmania was formed in 1842.
I very much doubt that Benjamin Dyer was the first preacher in Tasmania, but certainly one of the earliest. Rev Richard Johnson is my bet.
