Her first job after university was at the Tick Biology Station in West Burleigh, Queensland, where she collected data on the
tick life cycle for livestock management applications. Within a few months she was hired as a microscopist on the Australian
Hookworm Campaign. In the 1930s, she designed educational displays at the State Wheat Board in
Toowoomba, where her husband was an office manager. The book featured McKeon's own ink and watercolor illustrations, and was based on years of collecting invertebrates and plant life from her home at Point Vernon in
Hervey Bay. Her methodical gathering helped to build research collections of specimens at, among institutions, the
Queensland Herbarium. ==Personal life==
