Sabrina Down Under

Sabrina Down Under is a 1999 television film produced for ABC. It is a sequel to "Sabrina Goes to Rome" and is a companion to the "Sabrina the Teenage Witch" television series.
The film features only two characters from the TV series: teenage witch Sabrina Spellman (played by Melissa Joan Hart), and talking cat Salem Saberhagen (voiced by Nick Bakay). Lindsay Sloane was also a regular actress in the TV series, but plays a different character in this film. Tara Charendoff reprises her role as Gwen from "Sabrina Goes to Rome". As the film is set in Australia, none of the scenes are filmed on the original set of the TV series.
The film was directed by Kenneth R. Koch, who helped to produce "Sabrina Goes to Rome". He also directed many episodes of the television series and was a prominent producer of the show.
Unlike "Sabrina Goes to Rome", which is included in the season 7 DVD release of the "Sabrina the Teenage Witch" TV series, "Sabrina Down Under" was not included in any of the season sets. It was later released on a stand-alone DVD on February 7, 2017. Prior to this, the film has been released on VHS, and is available to stream on Hulu.
Plot.
Sabrina travels to Australia's Great Barrier Reef with Gwen, a fellow witch from England, for a week-long vacation where they try to help protect a hidden mermaid colony whose habitat is threatened by ocean pollution, and by local marine biologist Dr. Julian Martin, who is determined to find the colony as his claim to fame. While Sabrina finds a friendship with Barnaby, a "merman" from the mermaid colony, Salem the cat finds a possible romance with another witch-turned-into-a-cat named Hilary, but finds Sabrina's problems interfering with his plans. In order to prevent Julian from launching a search for the mermaid colony, she casts a spell to create a storm to keep him in port, which succeeds except that a lightning bolt knocks Sabrina unconscious, and when she comes to she learns she has lost her powers, at least temporarily.
Books.
As part of the "Sabrina the Teenage Witch" book collection, a book titled "Sabrina the Teenage Witch: Sabrina Down Under" is available. The book is written by Ellen Titlebaum. It is unnumbered, as is the first film's book adaptation. The other books in the series are numbered in reading order.
Music.
On February 7, 2017, the film was released on DVD with changes to the musical score due to copyright issues.
