Recent data indicates a dramatic surge in the Australian black market for tobacco and nicotine products, with at least 75% of all sales now being illegal. This trend represents a significant increase from just 12% in 2017, with nicotine consumption jumping by nearly 40% between 2017 and 2025. Experts, including former deputy chief medical officer Dr. Nick Coatsworth, attribute this spike primarily to escalating tobacco taxes, which have tripled the cost of legal cigarettes over the past decade. The high price of legal products, around $50 per pack, drives consumers to illicit alternatives costing under $25, benefiting organized crime. This shift is projected to cost the government billions in lost excise revenue over the next four years and poses a threat to Australia's previously world-leading tobacco control efforts, potentially escalating into a public health crisis.
