The third minister appointed to the district was Rev. Harry Gowing. He was married and it seems that during his stay the Sunday School was commenced. It was held every Sunday afternoon at 3pm. Special children's services were held once a month. It was not until the 30's that the Sunday School was held in the mornings. Services continued at Otford in private homes and at outlying centers. With the construction of the Tuberculosis sanitarium at Waterfall (Garawarra) in 1911, the Anglican minister of Helensburgh served as one of the chaplains. This involved taking Sunday services and numerous funerals.

When work began on the deviation in Otford, around 1914, Mr. James' shop lay in the way of the new line. A new shop and residence was constructed for Mr. James by the railways and the old shop moves and used as a site office. At the completion of the deviation the building and land was handed back to the community as a local hall. It became the center for Sunday church services until it was burnt down some 50 years later. It was used by the Progress Association who constructed a tennis court in front of the hall. It had the name Mr. James' hall.

In 1909 an Anglican church was constructed in Waterfall and given the name St. Paul's. It was a small weatherboard building situated in McKell Ave. up from the school. it contained hand hewn furniture and was lit by kerosene lamps. Because the village of Waterfall never had a large population, the church struggled to survive. The electric light was installed in 1948.
