Tea tree is a small tree in the myrtle family that grows in wet ground on the northern coast of New South Wales and southern Queensland, Australia.

The essential oil is produced commercially on plantations in New South Wales.

Interest in tea tree oil emerged in the 1920s when Australian researchers found it had up to thirteen times greater antiseptic activity than carbolic acid, then a well-known germicide.
