The Helidon Spa Water Company & The Helidon Spa Park
In 2007, Joan Webster literally wrote the book about the history of Helidon Spa. Two books are printed in the single volume. Most of the history on this website used this book as the reference and source of photos.
Full credit to Joan Webster for her dedication to documenting the history of the area. A copy can be found at the Gatton & District Historical Society and another copy at the Gatton Library, which is in the Lockyer Valley Cultural Centre, 34 Lake Apex Drive, Gatton.
