- CSIRO's invention of WiFi: Few Australian realise that the technology in their wireless gadgets was invented in Australia by the Australian Government's research lab.
- Integrated Communications Cap Lamp (ICCL): The ICCL is a belt worn battery pack to power the helmet light of miners. By using a compact and lightweight Lithium-Ion battery, the designers made room for extra communications and safety equipment on the same unit, such as an RFID tag, a radio, or a PED Text Pager. The PED Pager uses radio frequencies which penetrate rock and allow emergency messages to be sent to miners.
