Forbes continued the Presbyterian services commenced by Clow on 31 December 1837 in the "Pioneers Church" near the north west corner of William Street and Little Collins Street. The Church of England soon made exclusive claims to this communal building and so Forbes held services in Craig and Broadfoot's store in Collins Street until a temporary timber building called "The Scots' Church" was opened on the adjoining land loaned by David Fisher in July 1838. The site was between where the Olderfleet and Rialto buildings were subsequently erected (Lot 14 Section 2). It was essentially a large room with a fireplace.
