Round the Twist was a Logie Award-winning Australian children's television series about three children and their widowed father who live in a lighthouse and became involved in many magical adventures. The series is based on fantasy stories written by author Paul Jennings. Its first series was made in 1989. A second series, with many roles re-cast, was made in 1992. A third series, again re-cast, was made in 1999, followed by a fourth (with some roles again re-cast) in 2000.
Many external scenes were shot around the region of the Split Point Lighthouse in Aireys Inlet, Victoria, Australia.
The show's distinctive theme song, with the lyrics "have you ever... ever felt like this?..." was sung by Tamsin West, who played the lead female role of Linda in the first series. It borrowed lines from popular nursery rhymes such as "There Was an Old Lady Who Swallowed a Fly", "Humpty Dumpty" and "Rain Rain Go Away".
