Captain David Brown came to Paterson in the early 1830's. He may have formerly been the Captain of the Pandora, a coastal trader.
David Brown was the first proprietor of the Bush Inn. The Inn was built of stone and was situated about half a mile north of Paterson township on the Gresford road on the south bank of Browne's Creek. It was built well out of flood reach. A well appointed two story building with a shingle roof, it had six rooms upstairs; two large rooms below used as dining room and kitchen, three smaller rooms and a large bar room. .
David Brown was granted a publican's licence for the Bush Inn in June 1839.

.... From the Maitland Mercury 19 December 1846 - On Thursday after noon, the beautiful little schooner, built by Mr. David Brown, of the Paterson, made her first entrance into that river. In consequence of the additional interest of a boat race, the township was thronged with visitors. Shortly after one o'clock the gentlemen connected with the vessel arrived, and all the arrangements having been made, the props were knocked away, and the little vessel glided gracefully into the dancing waters which were thenceforth to be her home. The vessel was named with the usual formulae, by the Rev. W. Ross, the Paterson Packet Victoria. She is schooner rigged of about 70 tons burthen, and intended for the Paterson and Sydney trade. Upwards of 200 persons were present on the occasion, all seeming to take the liveliest interest in the proceedings. After the ceremony, about twenty of those present sat down to a capital lunch provided by mine host of the Paterson Hotel, Mr. Brown when every respect to creature comfort was duly paid
The Sydney Herald recorded the dimensions of the Paterson Packet - The vessel does great credit to Mr. Brown, by whom she was designed; her model is very good. The following are her dimensions: keel, 44 feet; length over all, 55ft 6 inches; beam, 17 feet 4 inches; depth of hold, 7 ft 3 inches; and measures about 62 tons O.M. She is well adapted for the river trade, drawing little water and carrying a large cargo and proves to be a fast sailer as well as a good sea boa
David Brown used this vessel to trade between Newcastle and Sydney. During his absence Mrs. Brown managed the Inn.

In December a public Dinner of the brethren of the loyal Paterson Union lodge was given to their late host David Brown at the Lodge Room in the Bush Inn. It was organised as a token of their esteem for his services as host of the Lodge for the last eight years. The room was tastefully decorated with evergreens and flowers for tie occasion. The table groaned under the good things prepared. The chair was taken by Mr. J. Duke; the vice chair was occupied by Mr. Stanbridge senior.

Flood at the Paterson
The Paterson and Allyn River experienced a destructive flood in April 1861. The river broke the banks in three different places within the vicinity of the town; a little below the Queen's Wharf, a little below the Scotch Church and near the Bush Inn; but did little damage. The Commercial Road leading from the town at the end of the Scotch Church ground was about eight feet under water and the same road a little beyond the Bush Inn was ten feet under water.
