Gulgong is a 19th-century gold rush town in the Central Tablelands and the wider Central West regions of the Australian state of New South Wales. The town is situated within the Mid-Western Regional Council local government area. It is located about north west of Sydney, and about 30 km north of Mudgee along the Castlereagh Highway. At the 2016 Census, Gulgong had a population of 2,521. Today, much of the 19th-century character of the town remains, contributing to its appeal as a tourist destination. Of special interest is the Prince of Wales Opera House, a survivor with a rich history. An attraction of note is the Gulgong Pioneer Museum, which has a huge collection of thematically-displayed exhibits, ranging from kitchen utensils to complete buildings that have been relocated to a "street" on the site. Apart from tourism and hospitality, local industries include wine production, wool, wheat growing and coal mining. Yarrobil National Park is located north west of Gulgong. History The name "Gulgong" is derived from the word used by the traditional inhabitants, the Wiradjuri, for "deep waterhole". Lieutenant William Lawson passed through the area in November 1820 and again in 1821 and reported good grazing land in the region. This prompted the brothers George and Henry Cox, sons of William Cox, to take up land to the south of the Gudgegong River, while Lawson applied for land grants to the north. Others soon followed, taking up land with river frontage along the Gudgegong. Among the first to take formal possession was Richard Rouse who was granted land in 1825 by Governor Brisbane. Gulgong came into existence after gold was discovered at Red Hill in 1870. The township was surveyed in August 1870. By the end of that year there were 800 people on the diggings, which yielded over 32 tons of gold in the 1870s. The population had increased to 12,000 by the time the British author Anthony Trollope visited in October 1871. The population of the town reached 20,000 in 1873. The Gulgong gold field was one of the last to be developed as "poor man's diggings", that is by individuals without substantial capital investment. Novelist and bush poet Henry Lawson lived briefly in Gulgong as a child in the early 1870s, while his father sought instant wealth as a miner. A montage of goldrush-era Gulgong street scenes was used as a backdrop to the portrait of Lawson
