sentences:  Dredging of the first channel through the Brisbane River and into the Brisbane Port began in 1862.Though the path was originally planned by Lieutenant G. P. Heath, RN, who was then appointed Marine Surveyor and was later to be appointed the Portmaster for Queensland, the path was later changed as the Superintendent of the dredge, Thomas Francis, located what he believed to be a better path.After much debate and a Select Committee of the Queensland Legislative Assembly, it was decided to continue with the path suggested by Francis.
