Offshoot of the popular TV show finds the teen witch (Melissa Joan Hart) on a trip with her friend (Tara Charendoff). There she finds romance with a merman.

Sabrina travels to Australia's Great Barrier Reef with her best friend 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 a local marine biologist, Dr. Julian Martin, determined to find the colony as his claim to fame. While Sabrina finds romance 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.—matt-282

This time around, perky witch-in-training Sabrina heads to Australia in the company of her British friend, Gwen. No sooner has the magical heroine arrived than she meets and falls for a muscular merman named Barnaby, who lives in a secret mermaid colony. Motivated by both love and a sense of ecological duty, Sabrina dedicates herself to saving the colony from discovery by a headline-chasing biologist, and from pollution caused by local fat-cat industrialists. Meanwhile, Sabrina's talking cat, Salem (actually a warlock who has been transformed into a cat), embarks upon a romantic adventure of his own with a similarly enchanted female feline named Hillary.
