Factual error: During the opening titles, when the camera is zooming throughout the plains, you can hear a rattlesnake in the background. There are no rattlesnakes in Australia.

Other: When "Krebbs" the koala is discussing with his other friends in the cell. If you look closely, you can notice a blink in the outline in the "Krebbs" nose. It's a clear ink & paint mistake of the blur line.

Factual error: When Bernard, Miss Bianca, and Jake are on their way to rescue Cody, they ride fireflies at night. Fireflies are only native to North America.

Continuity: When McLeach discovers Cody in the hole, McLeach reaches in with his shotgun to help Cody out. It would have to be a very large gun to reach into the bottom of the hole, yet when Cody is pulled out, the gun is shown to be quite small.
