St John's Catholic Church, completed in 1837, is the oldest Catholic church in Australia. The building is a simple Georgian colonial structure in locally quarried sandstone — modest by European standards but of considerable historical significance given its age and continuity of use. The church is still an active parish and holds regular services.
The church stands on a slight rise overlooking the village, giving it a quiet presence above the main street. The interior is plain but well-maintained, with original wooden pews and a small pipe organ. The graveyard around the church contains headstones from the convict era and beyond. A short visit is worthwhile for the building itself and the context it provides about the Irish convict experience in early Tasmania.
