Critical reception
In The Herald the reviewer called the novel "an excellent yarn of its kind, in which Mr Upfield has turned to the big game fishing grounds off the south coast of New South Wales, which he knows so well...Bony is sent for. He unravels the mystery in his usual efficient fashion and gives Mr Upfield an opportunity to provide a novel and realistic background. His public should be well pleased with Swordfish Reef."

K. A. in The Argus noted: "Mr Upfield has the knack of telling a detective tale and we salute him again for showing us how to introduce a true Australian atmosphere in a way that enhances his reputation."

In The Bulletin the reviewer concluded that "the descriptive passages, especially those relating to the catching of swordfish, are very well done, and in bringing Bonaparte from his usual haunts in the interior of the continent to its seashore Upfield has produced a book worth reading for its freshness and vigor."

Television adaptation
The novel was adapted for television in 1973 in a one-hour episode, titled "Boney and the Albatross", of the Boney series. It was directed by Peter Maxwell, from a script by Ross Napier.
