The article looks at the 75th anniversary celebrations of the Alice Springs School of the Air, which began lessons in 1951 and became the first school of its kind in the world. Covering more than 1.3 million square kilometres across Central Australia, the school has provided education to children living in isolated stations and remote communities. Former student Jane Hayes recalled the challenges of early radio-based lessons, where students sometimes struggled to hear teachers over interference from overseas radio traffic. The story traces the school’s origins to a 1944 proposal by Flying Doctor Service member Adelaide Miethke, who envisioned using two-way radios to educate children in the outback. While technology has transformed remote learning over the decades, the school continues to play a vital role for bush families, maintaining its reputation as “the world’s largest classroom.”
