The film is known as Bernard and Bianca in the Land of the Kangaroos in countries where the phrase "Down Under" is not as well known or is deemed as offensive. It also became the first fully digital feature film for Disney and the world.
Another Rescuers movie was planned for 1996, but after the deaths of Eva Gabor and John Candy, this and all future Rescuers movies were scrapped. Also, the disappointing box-office performance of the film discouraged the Walt Disney Company from releasing later sequels theatrically, with the exception of Return to Neverland and The Jungle Book 2, both of which proved to be box office successes.
In the Australian outback, a young boy named Cody is told by his friend, a kangaroo called Faloo, about a trapped Great Golden Eagle called Marahute, who is trapped on top of a cliff and that he is the only one who can set her free. After climbing the cliff, Cody rescues the eagle by cutting her bounds. In the process, he is accidentally knocked off the cliff but Marahute swoops down and catches him on her back just before he hits the ground. Befriending Marahute, Cody is taken on a ride through the air before been taken to her nest, where he is shown her three eggs that are close to hatching, and given a feather by her as a token of gratitude for freeing her. Later, the boy falls in a pit-trap by wanted local poacher McLeach. When McLeach finds one of the eagle's feathers in the boy's backpack he is instantly overcome with excitement, for he knows that to capture such a grandiose bird would make him rich. McLeach kidnaps the boy and attempts to force out of him the whereabouts of the rare eagle.
Meanwhile, a message is sent to New York to the Rescue Aid Society headquarters, and Bernard and Bianca, the RAS' elite field agents, are assigned to the mission, interrupting Bernard's attempt to propose marriage to Bianca. They go to find Orville, the albatross who aided them previously, but instead find Wilbur, Orville's brother. Bernard and Bianca convince Wilbur to fly them to Australia to save Cody. In Australia, they meet Jake, a kangaroo rat who is the RAS' local regional operative. Jake later flirts with Bianca, much to Bernard's chagrin. He serves as their guide and protector in search of the boy. Wilbur is immobilized when his spinal column is bent out of its natural shape, convincing Jake to consign him to the hospital.
Wilbur is taken to a wrecked ambulance where several medical mice “help” him with his back. They rope and put him in a harness which made Wilbur unsure about being left there, when Dr. Mouse orders the Nurse Mice the put a cane in his back, Wilbur begins to panic causing the head doctor to have him sedated. Three nurse mice load two syringes with tranquilizer into a double-barreled shotgun and shoot him in the rear. At McLeach's ranch, Cody has been thrown into a cage with several of McLeach's captured animals after refusing to give up Marahute's whereabouts. Cody tries to free the animals but is thwarted by Joanna, McLeach's pet goanna. Back at the hospital truck Wilbur wakes up painfully to find a vice on his head and a heart monitor attached to his beak, much to his fear and worry. While the head doctor gets ready he orders a set of forceps, sharpe teethed scrissors and a spur, and as the Nurse mice passed each off the “operation tools” Wilbur’s became more and more afraid (which made the heart monitor beep more faster every time his fear increases), but then the spur seemed to be rusted tight so Dr. Mouse orders for a “Epidermal Tissue Disrupter” which turns out to be a chainsaw. Wilbur panics, breaks free and runs for his life. Dr. Mouse and the nurses try to return him to the bed, while Wilbur tries to escape through a window, but then the mice who try to pull him back in and he falls flat back into the ambulance and his back is suddenly straightened up but the doctor’s back is damaged, and Wilbur sets out to find Bernard and Bianca. Back at McLeach' hideout he overheard the rangers talk about Cody and call of the search. McLeach decides to eat some eggs. This excites Joanna and she steals all the eggs while he tries to figure out a way to make Cody give the eagle. He realizes the eagles eggs are Cody' weakness. McLeach secretly lies to Cody telling him that someone else has shot Marahute, tricking Cody into leading him to Marahute's nest.
Bernard, Bianca, and Jake, half-aware of what is happening, jump onto McLeach's Half-track to follow him. At Marahute's nest, the three mice try to warn Cody that he has been followed; just as they do, McLeach arrives and captures Cody, along with Marahute, Jake, and Bianca. Wilbur arrives at the nest, whereupon Bernard convinces him to sit on the eagle's eggs, which Bernard had saved from Joanna moments before. McLeach takes Cody and Marahute to Crocodile Falls, where he ties Cody up and hangs him over the eponymous crocodiles. Bernard, riding a type of wild pig called a "razorback", which he had tamed using a horse whispering technique earlier used by Jake, follows and disables McLeach's vehicle, preventing the use of its crane from putting Cody at risk. McLeach then tries to shoot the rope holding Cody above the water. To save Cody, Bernard tricks Joanna into crashing into McLeach, sending them both into the water. The crocodiles chase McLeach, while behind them the damaged rope holding Cody breaks apart. Although McLeach manages to fight off the crocodiles, only Joanna reaches the shoreline while McLeach goes over a much larger waterfall to his death.
Bernard dives into the water to save Cody but fails. Jake and Bianca free Marahute in time for her to retrieve Cody and Bernard. Bernard, desperate to avoid any further incidents, proposes to marry Bianca, who accepts eagerly while Jake salutes him with a newfound respect. All of them depart for Cody's home. Wilbur, whom they have neglected to relieve of his task, incubates the eggs until they hatch, much to his dismay.
The Rescuers Down Under is notable for Disney as its first traditionally-animated film to completely use the new computerized CAPS process. CAPS (Computer Animation Production System) was a computer-based production system developed by Pixar that was used for digital ink and paint and compositing. This allowed for a more efficient and sophisticated post-production of the Disney animated films and making the traditional practice of hand-painting cels obsolete. The animators' drawings and the background paintings were scanned into a computer, where the animation drawings are inked and painted by digital artists, and later combined with the scanned backgrounds in software that allows for camera positioning, camera movements, multiplane effects, and other techniques.
As a result, The Rescuers Down Under was the first feature film for which the entire final film elements were assembled and completed within a digital environment. However, the film's marketing approach did not call attention to the use of the CAPS process. It is Disney's second animated feature that does not include any musical numbers, the first being Disney's The Black Cauldron. The film also uses CGI elements throughout such as the field of flowers in the opening sequence, McLeach's truck, and perspective shots of Wilbur flying above Sydney Opera House and New York City.
A team of over 415 artists and technicians were required for the production of the film. Five members of the team traveled to the Australian Outback to observe, take photographs and draw sketches to properly illustrate the outback on film.
On its initial release, The Rescuers Down Under was preceded by a short subject starring Mickey Mouse in an adaptation of The Prince and the Pauper. This was the second new Mickey Mouse short made since the 1950s, the first having been Mickey's Christmas Carol, which accompanied the 1983 re-release of The Rescuers.
The Rescuers Down Under features three characters from the first film: Bianca, Bernard, and the Chairmouse.

The Rescuers Down Under was released in the Walt Disney Classics video series in 1991 on VHS like The Rescuers. However, unlike The Rescuers, the film did not make it to the Walt Disney Masterpiece Collection. It was released on DVD on August 1, 2000, as part of the Walt Disney Gold Classic Collection. A DVD/Blu-ray combo pack of the film with The Rescuers was released as a 2-Movie Collection on August 21, 2012.
The film received a mostly positive response. On Rotten Tomatoes, 68% of the critics reviews were positive. But despite the critical success, the film underperformed at the box-office, grossing only $47 million, making it the least successful box-office performance of any major release of the Disney Renaissance era.
- This is only the second Disney animated film to not be a musical, with the other one being The Black Cauldron (which only showed Fflewddur Fflam singing at one point).
- The Rescuers Down Under is the only sequel to be released during the Disney Renaissance.
- On the Disney Junior broadcast, the scene in which Percival McLeach asks Cody if Marahute was hiding at either Satan's Ridge or Nightmare Canyon was omitted due to the aforementioned location's name and the second clip of McLeach throwing a knife next to Cody was replaced with a repeated clip of Joanna splitting her cracker in halves, due to it being violent. Also, during the hospital scene with Wilbur, the clip showing a chainsaw was removed, possibly due to it being too scary for younger viewers.
- The read along and novel books do not show us the scenes of Joanna's waving, McLeach's falling, Bernard's engagement to Bianca, or Wilbur abandoned on the nest. This might be to avoid spoilers if some people have not seen the film yet.
- This was the last Disney film to be theatrically accompanied by a half-hour featurette until 2017's Pixar film Coco (which was theatrically accompanied by the Frozen short sequel Olaf's Frozen Adventure).
