Cactoblastis Memorial Hall

Cactoblastis Memorial Hall is a timber-framed building in Boonarga with a pitched metal roof that sits on low supports near the Warrego Highway. Inside, a central dance room opens to side aisles, creating a simple layout that served community gatherings.

The hall was completed in 1936 to commemorate the arrival of cactus moths from South America that controlled spreading prickly pear plants. The insect became crucial to saving Queensland pasturelands from being overrun by the invasive plant.

The community of Boonarga sees the cactus moth as a symbol of rural survival and ingenuity that defined their region's past. The hall serves as a gathering place where this shared history continues to connect local residents through memory and pride.

The hall sits near the Warrego Highway and welcomes visitors interested in rural Queensland history. Check opening times in advance since hours can vary, and the building may be closed on certain days.

This is the only building in Australia dedicated to an insect species that rescued a region through natural pest control. Few places worldwide celebrate such an unusual ecological story with a dedicated memorial.
