Following the British Government's establishment of a penal settlement where the city of Brisbane now stands, an embargo was placed on the occupation of land within fifty miles of the ‘closed' penal establishment. Several officers of the colony made journeys of exploration up the Brisbane River, passing through the area which would become Fernvale. After Alan Cunningham's discovery in 1828 of Cunninghams Gap a wave of squatters travelled from Sydney via the inland areas of New England and the Darling Downs, bringing sheep to settle on the rich pastures of the Brisbane Valley, taking up runs of tens of thousands of acres.
