The Decriminalisation of Sex Work in New South Wales was a bi-partisan decision in 1995 following the Wood Royal Commission into Police corruption. Political leaders looked at the evidence and found that criminalisation of sex work caused corruption, limited sex workers access to justice and industrial rights, denied the community transparent and accountable regulation of sex work, and had a negative impact on public health. Decriminalisation of Sex Work in New South Wales is now an international best practice model both emulated and celebrated. Justice, public health, transparent regulation and human rights outcomes are optimum, all due to Decriminalisation. Decriminalisation is recommended by the Joint United Nations Programme on HIV/AIDS. In 2014 The Lancet concluded “Decriminalisation of sex work would have the greatest effect on the course of HIV epidemics across all settings, averting 33–46% of HIV infections in the next decade.” New South Wales has been ahead of the trend for over two decades. The Government of New South Wales wants to repeal Decriminalisation, despite the evidence that justice, health, policing and human rights outcomes are best met by Decriminalisation. Decriminalisation is the best option for sex workers. We the undersigned call on the NSW government to save decriminalisation for sex worker health and safety.
