8,400 Dung Beetles Travel by Express Post to Save Farms

When Tom O'Malley walked into his local post office in Tasmania, he could hear his packages buzzing from 10 meters away. Inside were 8,400 live dung beetles, freshly arrived by express post from South Australia.

The unusual delivery is part of a brilliant agricultural exchange that started almost by accident five years ago. South Australian farmer Matthew Robertson read an article O'Malley wrote about blue bomber beetles and reached out with an idea.

Robertson had thousands of Bubas bison beetles that work hard during winter and spring but go dormant in summer. O'Malley had an abundance of blue bombers active during summer and autumn but quiet in winter. Why not swap?

The exchange solved a real problem for farmers. Livestock manure needs to be broken down and mixed into soil throughout the year, but each beetle species only works part-time. By combining different species, farms get continuous coverage across all seasons.

Dairy farmer Matthew Gunningham received 1,000 Bubas bison beetles at his organic farm in northwestern Tasmania. "Dung beetles just really do an enormous amount of good," he said.

The beetles tunnel through manure and drag it deep into the soil, improving drainage and aeration. This process makes nutrients available to plants much faster than manure sitting on the surface. For organic farmers with limited chemical inputs, beetles are natural productivity boosters.

This marks Gunningham's third year receiving beetles, and he's watching the population establish itself. The species will eventually reproduce enough to sustain themselves without annual deliveries.

Getting thousands of beetles ready for their postal journey requires serious dedication. O'Malley spends six consecutive Sundays working 12 to 15 hours each, trapping, counting, washing and packing beetles.

He sets traps at dusk with cow dung on top. Beetles fly in thinking they've found a giant cow patty, tunnel through mesh and drop into collection containers. Each beetle gets washed in three to four consecutive buckets of water until spotless.

The cleaned beetles go into plastic boxes with air holes, cable-tied shut and packed inside postal boxes with clear labels. O'Malley drops them at the post office Monday mornings so they arrive in South Australia before the weekend.

"We send it and keep our fingers crossed that it doesn't get lost or damaged," he said. The beetles are then at the mercy of Australia's postal service.

The Ripple Effect

What began as two people connecting over a newsletter article has grown into a model for agricultural cooperation. Farmers across northwestern Tasmania now benefit from year-round manure management, leading to healthier soil and more productive pastures.

The exchange demonstrates how sharing resources between regions creates wins for everyone involved. Robertson gets summer-active beetles, Tasmanian farmers get winter workers, and the soil gets richer throughout the year.

O'Malley plans to continue releases until Bubas bison fully establishes in Tasmania's livestock-dense areas. Each shipment builds toward self-sustaining populations that will help farms for generations.

Sometimes the best solutions come from neighbors helping neighbors, even when those neighbors live across an ocean.
