Providing alcohol to under 18s

We know that it’s illegal for bar staff or bottle shops to serve or sell alcohol to people under 18, but what if they’re in a private home under adult supervision?

What is Secondary supply?

‘Secondary supply’ is a legal term used to describe an adult providing alcohol to someone under 18.

In Australia, it’s against the law to serve alcohol in a private home to anyone under 18, unless you’re the young person’s parent or guardian or, in the case of most states and territories, you have permission from the parent/guardian.

Secondary supply is the most common way that young people obtain alcohol, with 43% of underage people getting alcohol from their parents.1

Alcohol-related harms in young people

Australia’s drinking guidelines say to reduce the risk of injury and other harms to health, anyone under 18 years of age should avoid alcohol altogether.


Because drinking alcohol can affect how the brain develops in young people up until the age of 25.

This includes areas of the brain associated with attention, memory, and decision-making abilities.2, 3 Drinking alcohol while these areas are still developing could increase the risk of:

  • memory problems
  • learning difficulties
  • mental health issues
  • dependence.3-6

In fact, the earlier a young person starts drinking, and the more frequently they drink, the more likely they are to develop an alcohol dependence later in life.4, 5

While young people today are less likely to drink alcohol than previous generations, they’re actually more likely to ’binge drink’ and take risks which can result in injuries, alcohol poisoning and potentially death.7,8

The highest alcohol-related injury presentations in Australian emergency departments are for 15 to 19-year-olds.9

Current secondary supply laws in Australia

In Australia, it isn’t illegal for a person under 18 to drink alcohol on private property.

However, in most states and territories, the person who supplied them with the alcohol could be breaking the law – unless they’re the young person’s parent or guardian, or the parent or guardian has provided consent.

In all states and territories, it’s illegal to supply people under 18 with alcohol if responsible supervision is not provided.

Responsible supervision is generally determined by:

  • if the adult supplying the alcohol is intoxicated (when a person's speech, balance, coordination, or behaviour is noticeably affected by alcohol)
  • if the young person is intoxicated
  • the age of the young person
  • the type and amount of alcohol supplied and over what period of time
  • if the young person has eaten food with the alcohol
  • how the young person is supervised by the adult supplying the alcohol.
