A huge number of everyday legal questions in Australia come down to a single number: how old do you need to be? The trouble is that the answer changes depending on the topic, and sometimes depending on which state or territory you are in, which makes it easy to end up with outdated or simply wrong information.
This guide brings the most commonly searched legal age questions together in one place, with the current, correct answer for each, and a note wherever the rule varies by state rather than applying nationally.
The Quick Reference List
Here is the short version before the detail below. Where an age varies by state, this reflects the most common position rather than every possible variation.
- Age of consent: 16 in most states, 17 in South Australia and Tasmania
- Legal drinking age: 18 nationally
- Legal voting age: 18 federally, currently 18 in every state and territory
- Age to buy or use vapes and cigarettes: 18 nationally, with nicotine vapes now restricted to a prescription pathway
- Minimum working age: no single national age, generally around 14 to 15 depending on the state and type of work
- Age to get a tattoo without parental consent: 18 in most states
- Age of majority, or the age you are legally an adult: 18 nationally
- Legal gambling age: 18 nationally
- Driving age for a learner’s permit: generally 15 to 16 depending on the state
Age of Consent
The age of consent in Australia is 16 in New South Wales, Victoria, Queensland, Western Australia, the Northern Territory, and the Australian Capital Territory. South Australia and Tasmania set it slightly higher, at 17.
According to the Australian Institute of Family Studies, every state also has close-in-age defences intended to avoid criminalising consensual activity between peers who are close in age to one another.
Drinking, Vaping, and Smoking Ages
Legal Drinking Age
The legal drinking age is 18 across the entire country, covering both purchasing alcohol and consuming it in a public place. This is set consistently through state liquor licensing legislation, and the Department of Health, Disability and Ageing outlines the broader legal framework behind it.
Vaping and Cigarettes
The purchasing age for vapes and cigarettes is 18 nationally, but the rules around vaping specifically have changed significantly.
Since reforms that took effect from mid-2024 and tightened further from mid-2025, the Australian Government’s vaping reforms mean vapes, including non-nicotine ones, are now generally only available through pharmacies, with nicotine vapes requiring a prescription outside a limited over-the-counter pathway for adults.
General retail sale through convenience stores and tobacconists is no longer permitted.
Driving, Working, and Voting Ages
Learner’s Permit Age
There is no single national driving age. Most states, including New South Wales, Victoria, Queensland, the ACT, Tasmania, and the Northern Territory, allow learner’s permits from 16, while Western Australia and South Australia allow it slightly earlier.
Each state’s transport authority sets its own graduated licensing requirements from there, including minimum supervised hours before a provisional licence is issued.
Minimum Working Age
There is also no single national minimum working age. According to the Fair Work Ombudsman, rules are set at the state level, with restrictions on hours, the type of work permitted, and school attendance requirements applying to younger workers in every state, even where no strict statutory minimum age is set out.
Voting Age
The voting age is 18 federally, governed by the Commonwealth Electoral Act, and 18 remains the age in every state and territory election as well. There is active public and political discussion in 2025 and 2026 about potentially lowering the voting age to 16, similar to changes made in some other countries, but no change has passed into law, so 18 remains the current legal position.
Tattoos, Moving Out, and Kids in the Front Seat
Tattoo Age
Most states set 18 as the age to get a tattoo without parental or guardian consent, with several states, including New South Wales, Victoria, Queensland, and Western Australia, allowing tattooing of a minor only with written consent, and some restricting visible-area tattoos for minors even where consent is given.
Age of Majority and Moving Out
The age of majority, meaning full legal adult capacity to enter contracts and similar arrangements in your own name, is 18 nationally and consistent across every state.
A young person can sometimes leave home earlier with parental agreement or under specific arrangements, but full independent legal capacity begins at 18.
Children in the Front Seat
Front seat rules are tied to child restraint requirements and vary in their exact detail by state.
As a representative example, NSW road rules on child car seats generally require children under seven to use an approved child restraint or booster seat, with front seat travel restricted for younger children in most vehicles, before general front seat rules apply from around age seven onward.
Why So Many of These Rules Differ by State
It can seem strange that a country with one federal government has such a patchwork of age-based rules, but this reflects how Australia’s legal system is structured.
Criminal law, road rules, and matters like tattooing and working conditions for minors are largely state and territory responsibilities, while things like voting in federal elections and national alcohol and tobacco control frameworks sit with the Commonwealth.
This division means that whenever a rule genuinely matters for your situation, whether that is a parenting decision, a workplace question, or something with legal consequences, it is worth checking the specific rule for your own state rather than assuming a nationally quoted age automatically applies everywhere.
Many of these rules have also changed in the past few years, particularly around vaping and youth justice more broadly, so even a correct answer from a couple of years ago may no longer be current.
A Note on How These Rules Can Change
Age-based legal rules are not fixed forever. The vaping reforms discussed above are a recent example of a rule shifting quickly in response to public health concerns, and the ongoing debate about lowering the voting age shows that even long-standing thresholds like 18 are not necessarily permanent.
If you are relying on one of these ages for something important, checking the current position with an official government source, rather than an older article or a general assumption, is always the safer approach.
Conclusion
Most legal age questions in Australia come back to 18 for national matters like drinking, voting, and gambling, but driving, working, and tattoo rules are set state by state, and are worth double checking against your own state’s current rules if you need precision for a specific situation.
