A monitoring and site visit intervention to reduce sales to minors at packaged liquor outlets.

This intervention was associated with some of the lowest rates of underage alcohol purchasing reported to date. However, it may not be sustainable in the long term. It is recommended that: future studies randomise site visits to investigate their contribution to the observed reduction, cost effectiveness of the intervention is explored and legislative change to allow controlled purchase operations for alcohol is considered. SO WHAT?: Young people under 18 years of age should not be able to purchase alcohol from liquor licence outlets, and strong laws apply if a sale is detected. However, despite these rules, young people still report they can access alcohol in this manner. Whilst our intervention of site visits with the regulatory body saw decreases in sales to our pseudo-minors, we advocate for controlled purchase operations (similar to tobacco control) as a more sustainable and effective intervention to reduce sales to minors - while this is not yet legislated for packaged liquor outlets in Australia, it is deemed best practice in other countries.
