Set in the beautiful but isolated Kakadu National Park in the Northern Territory, Wildlife Ranger traces the duties and lifestyle of a national park ranger, including protection of and research into the diverse range of flora and fauna in the area. The program follows two rangers plying the boat along the waterways in the wet season to check out a remote rookery. This allows the viewer a close inspection of this unique environment, both at ground level and through breathtaking aerial photography. The northern monsoonal forests, grasslands and wildlife are shown in all their beauty, colour and diversity. The program also touches on the problems of remoteness from major towns, illustrated with the arrival of the fortnightly mail plane from Darwin.
