The Geebung Baptist church was initiated with a stump capping ceremony on Saturday 7 February 1925; prior to this services had been held in the war memorial hall. On Saturday 14 February 1926, the church was opened in a ceremony attended by 150 people. It was made of weatherboard and could seat about 100 people. The church (including fencing, the organ, the seating etc) cost £543/12/0 having spent £80 for the land. A new church was built about the 1960s. In May 2012 the Geebung Baptist congregation merged with the Sandgate Baptist congregation, selling their existing churches and establishing a new church, Connect Baptist Church at Deagon. In August 2013, the Geebung Baptist church was purchased by the Tonga Houʻeiki Church for $1.5 million, although the decision to purchase was controversial within the church.
