Twins and higher order multiples of all types and ages are welcome to register. Already, more than 33,000 pairs of Australian twins have joined the registry, making it the largest volunteer registry of its kind in the world. Even so, only about 17% of all twins living in Australia are currently members. If you are a twin, or the parent of twins under the age of 18 living in Australia, we would be pleased to have you register.

If you are under 18 we require your parent or guardian to register you and your twin. Please use the junior twin registration form.

If you are 18 and over you are able to register yourself and your twin. Please use the adult twin registration form.

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