No legal age for leaving children home alone
There’s no one law in Australia that says how old your child has to be before you can leave them alone.
In Queensland, if you leave a child under 12 years of age for an unreasonable amount of time without supervision and care, you have committed a criminal offence. But the legislation also says that whether the time is unreasonable depends on all the relevant circumstances.
Elsewhere in Australia, the law says you’re legally obliged to make sure that your child is safe and that your child’s needs are met. You can be charged with an offence if your child is left in a dangerous situation, not fed, clothed or provided with accommodation.
The police or child protection services can remove children from situations where they’re at risk of serious harm.
This means that you need to use your own judgment about leaving children home alone. This involves thinking about whether your child could cope if something happened while you were out or you weren’t able to get back.
For example, it’s never safe to leave a baby or toddler home alone. But you might feel OK leaving a pre-teen child alone for half an hour if they can follow household safety rules and know who to contact in an emergency.
Even if your child is mature enough to be home alone, you’re still responsible for their wellbeing and safety at all times.
