This document summarizes marine radio communication procedures in Australia. It outlines that maritime communication stations in Wiluna and Charleville monitor distress frequencies on HF radio and do not monitor MF, VHF, or 27 MHz frequencies. Coast radio stations operated by states and territories provide HF and VHF coverage up to 200 nautical miles offshore. They monitor distress frequencies on HF and VHF 16, and broadcast navigation warnings and weather reports. Proper radio channels and procedures are described for distress, safety, routine calls, and ship to ship communication.
