This ABC TV movie was a spinoff of the network's popular sitcom Sabrina the Teenage Witch, with Melissa Joan Hart (who also co-produced) again essaying the title role. This time around, perky witch-in-training Sabrina heads to Australia in the company of her British friend, Gwen (Tara Charendoff). No sooner has the magical heroine arrived than she meets and falls for a muscular merman named Barnaby (Scott Michaelson), 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 (Peter O'Brien), 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. Sabrina Down Under was originally broadcast as an episode of ABC's Wonderful World of Disney anthology on September 26, 1999.
