If your child is turning 18, it doesn’t just mark a significant milestone in their life. It marks one in yours too.
One minute you’re packing school lunches and reminding them to take a jumper. The next, they’re legally an adult, making their own healthcare decisions, managing their finances and preparing for the next exciting chapter of life.
It’s a proud moment, but if we’re honest, it can also feel a little overwhelming.
That’s exactly why we’ve created this Turning 18 Checklist. While your teen will gain exciting new freedoms, including voting, signing legal documents and, yes, legally buying their first drink, they’ll also take on a whole new set of responsibilities.

So, what can you do at 18?
Before we dive into the Turning 18 Checklist, it’s worth remembering that preparing your child for adulthood doesn’t begin on their 18th birthday; it starts years earlier.
Family psychologist Dr Ken Wilgus encourages parents to gradually step back as their teenagers grow, allowing them to take on more responsibility before they officially become adults.
His practical advice on navigating everything from independence and decision-making to dating and difficult conversations is well worth watching.
Turning 18 in Australia is about much more than celebrating with family and friends.
It means your teen officially becomes a legal adult. They can vote, sign contracts, make their own medical decisions and take greater responsibility for their finances, education and future.
For many parents, it can feel a little like pushing them out of the nest and hoping they remember everything you’ve spent the last 18 years teaching them. Thankfully, a little preparation goes a long way.
Our Turning 18 Checklist covers the legal, financial, health and practical steps every Australian family should consider before this exciting milestone.
Turning 18 Checklist: 25 Things You Need to Consider
Legal and Admin
1. Register to Vote
One of the first things on any Turning 18 Checklist should be enrolling to vote with the Australian Electoral Commission (AEC). Voting is an important part of Australian citizenship, so encourage your teen to enrol as soon as they’re eligible.
2. Update Their Identification
Whether it’s updating their driver’s licence or applying for an 18+ proof-of-age card, make sure all identification is current. Having up-to-date ID makes everything from opening bank accounts to travelling much easier.
3. Tax File Number (TFN)
If they don’t already have one, now’s the time to apply for a Tax File Number (TFN) through the Australian Taxation Office (ATO). A TFN is essential for employment and ensures they pay the correct amount of tax.
4. Superannuation
Many young adults don’t think much about super, but starting good habits early can make a huge difference later in life. Check that their employer is paying super correctly and consider consolidating multiple accounts if they’ve worked several casual jobs.
5. Update Their Bank Account
Many youth bank accounts automatically transition into adult accounts when your child turns 18. Review fees, interest rates, and account features together, and encourage them to start managing their own finances with confidence.
Mum Central Tip: This is a great opportunity to teach your teen how to read a bank statement, set a weekly budget and build healthy money habits.
Health
6. Apply for Their Own Medicare Card
A turning 18 checklist wouldn’t be complete without Medicare. If your teen is still listed on the family Medicare card, they can apply for one in their own name, giving them greater independence when accessing healthcare.
7. Health Care Card
If they’re eligible for Youth Allowance or other government assistance, they may also receive a Health Care Card, helping reduce the cost of medicines and some healthcare services.
8. Review Private Health Insurance
Many young adults remain covered under their parents’ private health insurance, but every insurer has different rules. Check whether they’ll continue to be covered and discuss whether they’ll eventually need their own policy.
Financial
9. Check Their Credit Report
Understanding credit is an important part of adulthood. Show your teen how credit reports work and explain why paying bills on time and borrowing responsibly can help build a healthy credit history.
10. Learn Budgeting and Saving
One of the most valuable life skills your child can develop is learning how to manage money.
Encourage them to:
- create a simple weekly budget
- save before they spend
- build an emergency fund
- avoid unnecessary debt
11. Start an Emergency Savings Fund
Unexpected expenses happen to everyone. Even putting aside a small amount each payday can help your teen feel more financially secure.
12. Youth Allowance
If your child is studying, training or looking for work, they may be eligible for Youth Allowance through Services NSW. Eligibility depends on factors such as study status and family income, making this an important item on your turning 18 checklist.
Personal
13. Update Emergency Contacts
Ensure emergency contacts are current and your teen knows who to contact if something unexpected happens.
14. Review Insurance
Depending on their lifestyle, it may be worth discussing car, travel, renters or income protection insurance.
15. Talk About Living Arrangements
Whether they’re staying at home, moving into student accommodation or renting their first place, take time to explain rental applications, bond payments, utility bills and tenant responsibilities.
16. Consider a Will
Although it may seem early, once your child turns 18 they’re legally responsible for making many important decisions. Having a basic Will is something to consider as part of long-term planning.
17. Check Their Passport
Planning a gap year or overseas holiday? Make sure their passport is valid before booking any trips.
Education and Career
18. Career Planning
Whether they’re entering the workforce, beginning an apprenticeship or heading to university, encourage them to explore their options and seek career advice if needed.
19. Consider a Gap Year
A gap year can be an excellent opportunity to travel, gain work experience, volunteer or simply recharge after the demands of Year 12.
20. Higher Education
Double-check that university, TAFE or other study applications have been completed and all important deadlines have been met.
21. Understand HECS-HELP
If university is on the cards, take time to explain how HECS-HELP works, including repayments and how the loan is managed through the Australian tax system.
Social
22. Join the Australian Organ Donor Register
Registering as an organ donor is a personal decision, but turning 18 is a good time to have that conversation. Many Australians choose to register when renewing or applying for a driver’s licence.
23. Join Clubs and Community Groups
Encourage your teen to join clubs, sporting groups or volunteer organisations. It’s a fantastic way to build confidence, friendships and valuable life experience.
Digital Life
24. Secure Their Online Presence
As your teen becomes more independent, protecting their digital identity is more important than ever.
Encourage them to:
- enable two-factor authentication
- use strong, unique passwords
- watch out for scams
- regularly review privacy settings
25. Store Important Digital Records Securely
Back up important documents securely and keep copies of identification, insurance information, and study documents somewhere safe and easy to access.
