The spiritual needs of Catholics in the Blackheath area were ministered to as early as 1842 by priests from St Bernard’s, Hartley. This arrangement existed until 1890 when the Blue Mountains parish, centred in Katoomba, was established. It serviced the needs of the congregations of Blackheath, Mt Victoria and Megalong until 1943.
The Sacred Heart Church was opened and blessed by Cardinal Moran on Australia Day, 1902. In May 1943, a new Parish District with its centre at Blackheath was created. The newly appointed resident priest assumed responsibility for a rather large area including Blackheath, Mt Victoria, Megalong Valley and a church hall at Medlow Bath.
