Main article: Bulahdelah tornado

An intense tornado, which occurred near the town of Bulahdelah (100 kilometres (62.1 mi) north-northeast of Newcastle), New South Wales on 1 January 1970, is thought to be the most destructive tornado ever documented in Australia.[3] It is thought to have reached F4 or F5 intensity on the Fujita scale, however, no official rating has been made public.[4][5] The tornado left a damage path 22 kilometres (14 mi) long and 1–1.6 km (0.6–1 mi) wide through the Bulahdelah State Forest.[3] It is estimated that the tornado destroyed over one million trees.[3] A caravan was destroyed and a 2-ton (2,000 kg) tractor was lifted into the air, landing upside down. The tornado was reported by witnesses as a swirling black cloud surrounded by flying debris, and producing a thunderous roaring sound.[6] The weather system that produced the tornado was a classic set-up for violent tornadoes, something somewhat rarely seen outside of the United States, Canada, Bangladesh, and adjacent areas of India.
