At the 2016 census, the locality had a population of 1,424. The main population centre, where 69% of the area's population lived in 2006, is the town of Bulahdelah.

The 292-metre-high (958 ft) mountain on which the south-eastern sector of the township is built was first named by the Aboriginal people of the area, the Worimi. They called their mountain "Boolah Dillah" (meaning: the Great Rock). In 1818 John Oxley, a crown surveyor added the word "Mountain" to its original name.The mountain is widely known by its long-term nickname, "the Alum Mountain", but is officially registered as Bulahdelah Mountain.After the discovery of alunite on the mountain, the mountain was mined from 1878 to 1927, and was managed by the Department of Mining from 1897 onwards. A refinery "The Alum Works" was created to facilitate the extraction of alum from the mined alunite. Another period of mining was then again from 1934 to 1952. Decreasing profitability meant mining had ceased by 1952 and in 1979 NSW State Forests took over management of the mountain.

Construction of the timber bridge across the Myall River was completed in 1892 and the bridge was formally opened on 28 July 1892. A 2-lane concrete bridge over Myall River was completed in 1969.In 1970 the Bulahdelah tornado swept through the nearby forests, just north of Bulahdelah in what was Australia's most destructive tornado on record.

On 3 May 2006 funding was approved (project approval was granted on 11 October 2007) for the relocation of the Bulahdelah section of Pacific Highway, to through the mid-slopes of Bulahdelah (the Alum) Mountain. Major construction of this highway deviation, known as the Bulahdelah Bypass, commenced in August 2010. The bypass was completed in July 2013.
