How to register

If you are over 18 years of age, you can register using the adult twin registration form.

Twins under 18years of age can be registered by a parent or guardian using the junior registration form.

To register by phone, please call us on 1800 037 021 (free call Australia wide).

We will send out a welcome pack to all newly registered pairs; if you do not receive a confirmation phone call from us and a welcome pack please contact us.

Why we need you

We all know that twins are special but many don’t realise the significant contribution they can make in the worldwide fight against many medical conditions such as asthma, diabetes and heart disease – and just how easy it is for twins to be involved and to make a real difference. Twins help us to better understand the impact of genetic and environmental factors on health and disease in a very special way. The Australian Twin Registry connects twins and researchers together. By joining the ATR you belong to a unique group that gives back to the community in the easiest and most useful way possible – with your time!

It doesn’t matter how old you are; if you are identical or fraternal, well or ill, boy, girl or opposite sex pair – all are welcome to join. Twins of all ages can join the registry and help but children must be registered by their parents if they are under 18 years of age.

Please note that there is no cost involved; it is free to join the ATR.

What being a member involves

Twins who register with the ATR are placed on our database and are contacted when there is an appropriate study and about research findings. We will also update you about ATR activities such as research seminars, twin events and membership benefits.

We always have new studies coming up – you may be interested in some and not others and that’s fine – you always have a choice whether to participate or not. Your involvement is voluntary and you can withdraw from a study or the ATR at any stage. Common activities include filling in questionnaires and health check-ups.

All projects that request to use the Australian Twin Registry are carefully reviewed. Approved projects must satisfy ethical guidelines and be of significant value to the area of proposed research. Information concerning individuals on the Registry is strictly confidential; personal details will not be given out without your consent.
